The objectives of this work are to determine the profiles of the countries that make up the European tomato consuming market and to observe if the economic-financial crisis (2007/2008) has influenced them. Both Lafay’s economic indicators were applied and country profiles and subprofiles were identified through a multilevel two-stage cluster analysis. The empirical analysis covers the period from 2005 to 2016, separated into two periods, pre-crisis (2005–2010) and post-crisis (2011–2016). Most countries obtained import and export profiles that coincide in both indices, Except in Italy. Only one post-crisis profile change was detected, this being for Greece, from an importer to an exporter. As a result of the initial two-stage clustering analysis (both in the pre-crisis and post-crisis period), three clusters were obtained. At the first level of clustering, Italy is identified with a producer profile and Spain and the Netherlands with an exporter profile. At the second level of clustering of the initial larger group, two clusters were identified, Germany and the United Kingdom with an importing sub-profile, and France and Belgium with an exporting sub-profile. In the transition from the pre-crisis to the post-crisis period, Portugal changed from a producer sub-profile to an exporter sub-profile.

Abstract The importance of segment of flowers and ornamental plants in agribusiness are growing. Researches that analyze the situation of different sector of this segment may contribute to establishing politics and actions to stimulate its development. In order to attend this purpose, the aim of this research was to analyze segments of the flower and ornamental plant production chain, focusing on producers and retailers. For that, two different surveys were applied, composed of direct and indirect questions. The application was performed online, using social media or in person, in the company location or in trend fairs. It was observed that the flower and ornamental plant production is mainly a familiar business. Another important issue is that the springtime consists of a new date for flower and ornamental plant commercialization. The number of retailers has been increasing, and this segment had some improvements as sales of different products and services. The flower and ornamental plant commercialization are still, in the majority, in physical location shops, besides of all the technologies available for online sales.

Testo completoAbstract (sommario):
Sugarcane honey (SCH) is a syrup produced on Madeira Island and recognized by its unique aroma, a complex attribute of quality with an important influence on the final consumer’s acceptance of the product, and determined by a complex mixture of a large number of volatile organic compounds (VOCs) generated during its traditional making process and storage. Therefore, the purpose of this study was to establish the volatile profile of genuine SCH produced by a regional certified producer for seven years and compare it with syrups from non-certified regional producers and with producers from different geographical regions (Spain, Egypt, Brazil and Australia), as a powerful strategy to define the volatomic fingerprint of SCH. Different volatile profiles were recognized for all samples, with 166 VOCs being identified belonging to different chemical classes, including furans, ketones, carboxylic acids, aldehydes and alcohols. Chemometric analysis allowed (i) the differentiation between all syrups, being more pronounced between SCH and other syrups; and (ii) the identification of 32 VOCs as potential markers for the traceability and authenticity of SCH on the global market.

Foot infections in patients with diabetes mellitus are a major cause of morbidity, can lead to gangrene and ultimately amputation of the limb. Aim of the study was to determine the type of microorganisms isolated from the Diabetic foot ulcer and antibiotic resistance pattern. We have included 50 patients having diabetic foot ulcers of Wagner's grade 1 or above in our study. Debrided tissue, pus, or swabs from the base of the ulcers were subjected to aerobic and anaerobic culture. The organisms were identified, and further antibiotic sensitivity was conducted. Seventy-two aerobic and 13 anaerobic organisms were isolated. Among the aerobic and anaerobic bacteria isolated, most predominant organisms were S. aureus and Bacteroides spp.; respectively. Of the S. aureus, 77.8% were methicillin resistant, while 42.1% of gram-negative Enterobacteriaceae were extended spectrum beta-lactamase (ESBL) positive. Klebsiella spp. was the highest ESBL producer. Acinetobacter spp. was the highest MBL producer. Most sensitive drugs for S. aureus were linezolid, vancomycin and amikacin. Gram-negative bacteria were mostly sensitive to piperacillin-tazobactam and amikacin. Pseudomonas spp. were usually sensitive to meropenem, piperacillin -tazobactam. Acinetobacter spp. was sensitive to colistin, tigecycline. As diabetic ulcers are often infected by multidrug-resistant bacteria, a knowledge of the common bacterial pathogens implicated as well as their sensitivity pattern helps the clinician to choose the proper antibiotic for a timely treatment.

Purpose This study aims to determine the physicochemical and fatty acids composition of Serra da Estrela cheese (SEC), as well as health-related lipid indices, like the atherogenic and thrombogenic indices, and to evaluate the influence of producer, geographical origin and production date. Design/methodology/approach All 24 SEC produced between November 2017 and March 2018 were collected at selected certified producers and analyzed by NIR spectrophotometer and by GC. Data were statistically evaluated by chemometric tools. Findings In all evaluated SEC, 23 fatty acids were quantified. Cheese origin influenced nutritional and health-related lipid indices). The cheeses were characterized by a relative high abundance of saturated fatty acids (67-76%), followed by a medium content of monounsaturated fatty acids (17-25%) and by low level of polyunsaturated fatty acids (5-7%). A putative positive association between cheese consumption and healthy lipid indices could be reached. Practical implications The contents of some medium and long chain fatty acids as well as of nutritional and health indices were influenced by cheese producer, geographical origin and production date pointing out the need for standardizing production procedures. Social implications The SEC plays a key role in the local economy, being an endogenous product with unique sensory characteristics and nutritional potential, for which the knowledge of the lipids profile and health indices is of utmost relevance. Originality/value SEC is an iconic Portuguese cheese with Protected Designation of Origin. Based on the results, like health-related lipid indices, evaluated for the first time, a positive association between cheese consumption and healthy lipid indices could be envisaged.

"Comparation of Phenotypic and Genotypic Profile of Carbapenemase Producing Escherichia coli". Folia Medica Indonesiana 54, n. 1 (5 aprile 2018): 10. http://dx.doi.org/10.20473/fmi.v54i1.8045.
Testo completoAbstract (sommario):
Carbapenemase-producing Escherichia coli (E. coli) has caused trouble in therapeutic antibiotic selection. Carbapenemase screening procedure in laboratories is usually based on inacurate semi-automatic system. Confirmation and classification of carbapenemases according to Ambler can be done with combination of phenotypic methods, i.e., Modified Hodge Test (MHT), Sodium Mercaptoacetic Acid (SMA), and 3-Aminophenylboronic Acid (PBA). This study aimed to compare profiles of carbapenemase-producing E. coli which were confirmed and classified phenotypically with the genotypic profiles. E. coli isolates from urine specimens which were potential as carbapenemase-producers according to semi-automatic system BD Phoenix were phenotypically tested with MHT, SMA, and PBA. Isolates were grouped as carbapenemase-producers and non carbapenemase-producers. Phenotypic carbapenemase-producer isolates were classified based on Ambler criteria. All isolates were then tested with Polymerase Chain Reaction (PCR) for the presence of OXA-48, IMP1, IMP2, GES, VIM, NDM, KPC genes. Out of 30 isolates, 6 isolates (20.0%) were MHT positive, and 25 isolates (83.3%) were SMA positive, which indicated that most isolates produced were carbapenemase Ambler B. PCR confirmed 12 isolates (40.0%) had VIM gene which were classified as carbapenemase Ambler B. Phenotypic confirmatory test had 100% sensitivity and 22.2% specificity. Classification with phenotypic confirmatory test had 91.7% match with PCR. Phenotypic confirmatory test detected more carbapenemase than PCR. This low specificity may be caused by inappropriate use of diagnostic gold standard. PCR should not be used for routine carbapenemase confirmation because of vast diversity of carbapenemases. Phenotypic confirmatory test can classify carbapenemase according to Ambler classification.

This research work investigated cellulase production potentials of the microbial profile of three sugarcane bagasse dumping sites at Zango area, Ilorin, Nigeria. The microbial isolates were screened for cellulase production with a view to select the best organism for eventual cellulase production. Pour Plate method was used for the isolation and a total of thirteen (13) different organisms including both fungal and bacterial species were isolated and screened. Six (6) fungal isolates identified as Mucor racemosus, Aspergillus niger, Aspergillus flavus, Neurospora sitophilus, Penicillium oxalicum and Penicillium citrinum were isolated, while seven (7) different bacterial species isolated include Clostridium cellobioparum, Clostridium thermocellum,Bacillus subtilis, Bacillus pumillus, Lactobacillus spp, Pseudomonas flavescens and Serratia spp. Generally, bacterial isolates were more in abundance than fungal species. However; fungal isolates were constant and were isolated through the experimental period of three weeks. All the isolates showed cellulase production potential in varying degrees as reflected in the clearance zone around their colonies. Fungal isolates produced more cellulase than the bacterial isolates. Mucor racemosus had the highest clearance zone (75.0 mm) among the fungal isolates while Clostridium cellobioparum (35.0 mm) were the best producer among bacterial isolates. The least producer among fungal isolates, Penicillium citrinum (40.0 mm), is a little more than the bacterial cellulase producer (35.0 mm) and is far greater than the least bacterium Serratia spp (14.0 mm).

This paper compares the pressure drop profiles of both horizontal well producer and injector in a 5spot waterflood pattern. Dimensionless pressure distributions for each pattern were utilised. All computations were limited to conditions of unit mobility ratio; i.e., before water breakthrough condition. Results show that a normal 5-spot flood pattern, with a horizontal well producer, offers higher pressure drops, but early water breakthrough tendencies, than as an injector for the same reservoir and wellbore conditions. An inverted pattern, under the same conditions, produces clean oil for a longer time, before water breakthrough possibilities.

Aspergillus spp. are a common contaminant of grapes and a major source of mycotoxins. China is the largest producer of grape in the world now, however, the toxigenic Aspergillus population on grape in this country is still largely unknown. In this study, a total of 345 strains were isolated from grapes of 13 main grapevine producing regions in China. Based on calmodulin gene sequences, eight species within Aspergillus section Nigri were identified. Among them, Aspergillus tubingensis (48.7%) was predominant, followed by Aspergillus welwitschiae (20.6%) and Aspergillus aculeatinus (11%). Average of contamination level was up to 64.19%, and we found the occurrence of section Nigri species on the surface of fresh grapes was significantly influenced by the climate (P<0.05). The subtropical monsoon climate showed the highest fungal detection rate (72.45%), followed by the temperate monsoon climate (49.82%), and the lowest frequency was found in the temperate continental climate (37.23%). Regarding mycotoxin-producing capacity, 4.4% of the total tested section Nigri isolates (137) were positive for ochratoxin A (OTA) production and 59.6% were fumonisin B2 (FB2) producers. Of those, Aspergillus carbonarius was the main OTA producer and A. welwitschiae and Aspergillus niger were the main FB2 producers with different toxigenic ability. Our results highlight the potential risk of OTA and FB2 contamination by A. carbonarius and A. welwitschiae on grape in China, respectively; management strategies should be considered for preventing and reducing the toxigenic Aspergillus and its mycotoxins.

Abstract As the profile of the arts-and-health sector grows and interdisciplinary projects with public outcomes become more common, it is useful to explore roles and ways of working at the interface between different disciplines. The authors analyze the complex role of producer, likely to become increasingly relevant in this landscape. While incorporating aspects of existing roles (e.g. hospital arts manager, cultural venue participatory producer, independent creative producer, public engagement manager), the producer has a very specific raison d'être and could be defined as “relational producer.” This role is not well understood and yet central to this field of practice.

Testo completoAbstract (sommario):
Summary Rigorous validation of a simulation model of the toe-to-heel air-injection (THAI) process has been performed using results obtained from a 3D combustion-cell experiment on Athabasca oil sands. The numerical model includes a new kinetics formulation, based on the Athabasca thermal-cracking kinetics scheme proposed by Phillips et al. (1985). The kinetics model excludes low-temperature oxidation because THAI operates in a high-temperature oxidation mode. Excellent agreement was obtained between the predicted and experimental oil-production rate, and there was generally a good match obtained for other dynamic variables, including the residual coke profile, produced oxygen, and peak combustion temperature. The numerical model provides a fundamental platform for upscaling to field scale that will enable fine-scale details of the process to be captured. Simulations were performed under dry in-situ combustion (ISC) conditions at the high air-injection fluxes used in the experiment. Under these conditions, vertical-plane temperature profiles in the sandpack confirm that the combustion front is quasivertical and forward leaning in the direction of the heel of the horizontal producer well. The shape of the combustion front was predicted more accurately from horizontal-plane profiles, showing that there was no oxygen in regions ahead of the combustion front. Oil displacement occurs mainly by gravity drainage, but pressure drawdown into the horizontal producer well below the mobile-oil zone (MOZ) is also significant. Various zones that develop during the ISC process include a steam zone located in the upstream part of the MOZ. All of the mobilized oil is produced from the MOZ, which is composed of two distinct oil regions. The first part contains oil produced by thermal cracking of the heavy residue and vaporized lighter oil. The main bulk of the oil produced in THAI comes from the second region of the MOZ, containing banked original oil. The oil that is eventually produced is partially upgraded oil because of the thermally upgraded and lighter oil fractions mixing with the original oil when they enter the horizontal producer well.

Rice husk is the waste from agriculture industries that has high potential to produce heat and electricity through the gasification process. Air suction mode is new development for updraft rice husk gasification, where blower are placed at output of gasifier. The objective of this research is to examine these new configuration at several equivalence ratio. The equivalence ratio was varied at 32% and 49% to study temperature profile on gasifier, producer gas volumetric flow rate, composition of producer gas, producer gas heating value, cold gas efficiency and carbon conversion. The time needed to consume rice husk and reach an oxidation temperature of more than 700oC for equivalence ratio of 49% is shorter than 32%. Producer gas rate production per unit weight of rice husk increase from 2.03 Nm3/kg and 2.36 Nm3/kg for equivalence ratio of 32% and 49%, respectively. Composition producer gas for equivalence ratio of 32% is 17.67% CO, 15.39% CO2, 2.87% CH4, 10.62% H2 and 53.45% N2 and 49% is 19.46% CO, 5.94% CO2, 0.90% CH4, 3.46% H2 and 70.24% N2. Producer gas heating value for equivalence ratio 32% and 49% is 4.73 MJ/Nm3 and 3.27 MJ/Nm3, respectively. Cold gas efficiency of the gasifier at equivalence ratio 32% is 69% and at 49% is 55%.

Background: In urinary tract infections, an important role is played by bacterial biofilms which are responsible for persistence infections together with the antimicrobial resistance. Higher resistance can be seen in biofilm forming uropathogens in comparison with free-floating bacteria. So, the present study was performed with a goal to find the prevalence of biofilm formation and also the antimicrobial resistant pattern of uropathogens.Methods: A descriptive method was conducted at Modern Technical College, Sanepa, Lalitpur in samples isolated from UTI suspected patients. The overall duration of this study was approximately 3 months. Total of 50 isolated E. coli was tested for biofilm formation and antimicrobial susceptibility testing was done by Kirby-Bauer disc diffusion method on Mueller Hinton agar as per CLSI guidelines.Results: From the 50 isolates of E. coli, 32 were biofilm producers (3 strong and 29 moderate) and 18 were weak/non-biofilm producers. Among the biofilm producers, cefotaxime was more resistant in 20 of the isolates followed by ceftriaxone in 16 and amoxyclav in 13, whereas amikacin was least resistant in 2 of the isolates.Conclusions: Among the isolated E. coli, biofilm-forming isolates showed higher antimicrobial resistance as compared to the non-biofilm producer. Thus, uropathogen should be routinely screened for biofilm formation.

Testo completoAbstract (sommario):
This study was carried out to analyze the suitability of the identification of four indigenous cellulose-producing acetic acid bacterial isolates (ANG29, KRE65, ANG32 and SAL53) based on the analysis of whole cellular protein profiles against identification based on phenotypic traits. Whole cellular protein profiles were determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) method. The whole cellular protein profiles obtained from sample isolates, were compared with reference isolates for species identification. The results showed that based on visual observations can be determined as much as 12 bands of protein with a molecular weight of 19,099 KDa up to 132.182 KDa. Based on the analysis of protein bands were detected visually, fourth indigenous cellulose- producing acetic acid bacterial isolates in the study had a higher similarity profile to the reference strain Gluconacetobacter xylinus BTCC 769 compared with other reference strains namely G. hansenii NBRC 14820T. This condition is consistent with the results of the identification of fourth cellulose producing acetic acid bacterial isolates based on phenotypic traits. Thus, the whole cellular protein profiles by SDS-PAGE technique can be used as a one of method to identification of cellulose producing acetic acid bacterial isolates.

Testo completoAbstract (sommario):
Muscovy duck is a type of waterfowl that has a relatively better growth and percentage compared to ducks. Duck meat has high-quality because of its low fat and savory flavor. Muscovy duck is relatively resistant to the disease and is able to use low-quality feed, but has the disadvantage of low egg production. The development of Muscovy duck as a producer of meat can be done through two approaches, namely the long-term and short-term. The long-term approach is carried out by selecting Muscovy duck which has high growth rate and high meet quality. The selection can be done in two ways, namely directly on the nature of growth and the quality of meat, and indirectly by choosing a marker of growth (morphology, biochemistry or diversity of DNA/ RNA). Short-term selection can be done by bringing in superior Muscovy duck from the outside to be developed by farmers and crossing male Muscovy duck with the layer Indian Runner ducks to produce Serati ducks.

Testo completoAbstract (sommario):
Escherichia coli is capable of producing several virulence factors involved in the pathophysiology of bovine mastitis. Cell surface structures such as flagella, pili, and other outer membrane adhesins are considered essential for biofilm formation on abiotic surfaces. The aim of this study was characterize the molecular profile of E. coli isolates obtained from mastitic milk by using the technique of pulsed-field gel electrophoresis (PFGE) and evaluating results within the pulsetypes formed with the presence of virulence genes involved in biofilm production. Twenty-seven E. coli biofilm-producing isolates were obtained from mastitic milk samples belonging to Brazilian Agricultural Research Corporation; these samples were analyzed by PFGE. We identified 9 (I to IX) different phylogenetic groups with a similarity of 90% and observed the presence of fimA (large subunit of the fimbriae type 1) and csgA gene (large subunit of curli fimbriae) in all isolates. Sixteen isolates had the gene fliC (flagellin). Evaluation of the genetic profile carried out through the PFGE showed that the bacteria do not share the same origin. It was not possible to associate the biofilm production capacity with the presence or absence of related genes. Therefore, strains of environmental mastitis-causing E. coli present different pathotypes.

Testo completoAbstract (sommario):
Streptomyces spp. have been major contributors of novel natural products that are used in many application areas. We found that the nojirimycin (NJ) producer JCM 3382 has antimicrobial activity against Staphylococcus aureus via cellular degradation. Genome analysis revealed 30 biosynthetic gene clusters, including those responsible for producing antibiotics, including an azasugar NJ. In-depth MS/MS analysis confirmed the production of 1-deoxynojirimycin (DNJ) along with NJ. In addition, the production of tambromycins, setomimycin, and linearmycins was verified by spectroscopic analyses, including LC-MS and NMR. The distribution of the clusters of genes coding for antibiotics in 2061 Streptomyces genomes suggested potential producers of tambromycin, setomimycin, and linearmycin. For a DNJ gene cluster, homologs of gabT1 and gutB1 were commonly found; however, yktC1 was identified in only 112 genomes. The presence of several types of clusters suggests that different strains may produce different types of azasugars. Chemical-profile-inspired comparative genome analysis may facilitate a more accurate assessment of the biosynthetic potential to produce secondary metabolites.

Testo completoAbstract (sommario):
It was obtained that the yeast Torulaspora globosa VKPM Y-953 is suitable for the production of biodiesel fuel. Zinc plays an important regulatory role in the metabolism of the studied strain. The study of the growth parameters and the fatty acid profile of the yeast T. globosa showed that the limitation of its growth by ethanol, at different concentrations of zinc in the medium, considerably influences the chemical composition and the energy content of yeast cells, but not their yield by weight (Yx/s). The increased concentrations of zinc in the medium, in combination with the yeast growth limitation by ethanol, elevated the content of lipids in the cells by 28% and diminished the content of proteins by 14%. At the same time, the limitation of yeast growth by zinc decreased Yx/s and energy (ηX/S) by 2.6 and 3.1 times, respectively. In this case, the content of lipids in cells fell by 72%, while that of proteins rose by 65%. The fatty acid profile of the T. globosa cells was used to estimate the main characteristics of biodiesel (iodine value, cetane number, density, and kinematic viscosity). The biomass of T. globosa can also be used in agriculture as a feed additive rich in essential amino acids.

Abstract. Residual soil water after harvest and prior to planting was measured to a depth of 2.4 m with neutron attenuation techniques for approximately 45 irrigated corn and 45 dryland wheat fields annually from 2010 through 2012 in the western one-third of Kansas. The sampling locations were in three-county transects in northwest, west central and southwest Kansas with generally five fields for each crop type for each county. Residual plant available soil water (PASW) in corn fields was generally much greater than in wheat fields (150%-160% greater) for any given sampling period illustrating the residual influence of irrigation. Although weather conditions varied between regions and years there was not a strong effect on PASW in irrigated corn fields but there was an effect in dryland wheat fields. Annual differences in fall irrigated corn PASW for the 21 individual fields that were available for sampling in all three years varied less than 50 mm/2.4 m soil profile implying considerable stability in an individual producer’s response (irrigation management and irrigation system capacity) to changing weather conditions as evidenced by the similar year-to-year PASW values. Drought conditions existed for much of the total period (fall 2010 through fall 2012) in southwest Kansas, yet the irrigated corn PASW was still relatively high (PASW value at approximately 62% of water stored at field capacity in a 2.4 m profile). So, the presence of drought may not be a good indicator of the amounts of residual soil water producers are leaving after irrigated corn harvest. Although differences in irrigated corn PASW varied greatly among producers (183% to 722% within a region), there were much smaller differences between regions and years with a variation from 8% to 22%. Irrigation system capacity (flowrate/area) had very little effect on residual fall PASW in the corn fields possibly indicating that producers with deficit capacity are pumping earlier and later into the season to help mitigate their lower irrigation capacity. Irrigated corn grain yields began to plateau when PASW reached a value of approximately 200 mm/2.4 m profile which would represent a water storage of approximately 56% of field capacity. The residual PASW in irrigated corn fields decreased about 1 mm for each 2 mm decrease in irrigation and cropping season precipitation illustrating the difficulties that can arise in managing for a target residual PASW. These results suggest that producers should be scheduling irrigation with science-based methods, rather than habits and previous experiences. Keywords: Corn, Field capacity, Soil moisture content, Soil water, Volumetric water content, Wheat.

The article introduces the notion of the European financial co-production, characterized by the mandatory cultural value of the script and empowerment of the minority co-producer through risk-sharing in financing. Eurimages, the Council of Europe’s film fund, inaugurated the first policies promoting European financial co-productions more than two decades ago by introducing the European Convention on Cinematographic Co-production. Many European film funds have followed the same policies on the national level, but the Danish Film Institute has been by far the most innovative. This article explores in more detail the DFI’s internationalization policy actions, particularly its minority co-production scheme, which democratized the practice of European co-production that traditionally had been the sole purview of a narrow circle of high-profile European producers. The shift enabled young Danish producers to engage in minority co-productions, popularizing co-production as a model among Danish producers of all calibres and triggering a dynamic knowledge transfer between co-producers.

<p>In this research, we combine data analyses with hotspots method to identify the spatio-temporal trend of São Paulo’s coffee cultivation area. Our hypothesis is that coffee cultivation area has been changing significantly in the study area since 1990. Therefore, the main goal of this research was to map the spatial pattern of coffee land use change. For coffee land use diagnostics, official data of cultivated area, hotspot analyses and growth rate were used. The results demonstrated that coffee cultivation area decreased and concentrated in smaller areas, which are traditionally recognized as “coffee quality regions”. The producer size analyses evidenced that, not only the localization, but also the producer profile changes as well. Smallholders increased but medium and large producers decreased significantly in the studied period. The coffee abandonment analyses demonstrated that, over the study period, 51.46% of the coffee area cultivated in the study region was abandoned. </p>

Urinary tract infections are the second common reason of medical consultations and antibiotics prescription. Escherichia coli is known to cause most urinary tract infections. The aim of this study was to characterize and determine the antibiotic resistance profile of E. coli extended-spectrum βlactamases (ESBL) producer strains isolated from urine samples. The urine samples collected came from hospitalized and non-hospitalized patient referred to Hubert Koutoukou Manga (HKM), National and University Hospital Center (Cotonou, Benin). The resistance to antibiotics was determined according to the disk diffusion method. The production of penicillinase and ESBLs was researched respectively by the acidimetric test and double disk synergy method. The presences of genes encoding βlactamases were detected by Polymerase Chain Reaction (PCR). Our data revealed that 60 % of E. coli strains (101) were isolated from female patients. Also, 69.31 % of the strains were isolated from non-hospitalized patients. The high resistance levels were recorded with amoxicillin (96.04 %) and amoxicillin + clavulanic acid (66.34 %). Twenty percent (20%) of strains were ESBLs. Among ESBLs strains, 70% comes from non-hospitalized patients. Eighty percent of E. coli strains produced penicillinase among which 25 % were ESBL producers. All the ESBL producers strains carried blaTEM gene whereas only 30 % carried the blaSHV gene. This study updates the data on the prevalence to antibiotic resistance of E. coli ESBL producers strains for better management of urinary tract infections.

SUMMARYPlasmid profile typing has been used to subdivide phage-type 49 ofSalmonella typhimurium, the most common phage type in humans in England and Wales since 1985. Twenty profile patterns have been identified in 350 strains examined.Four profile patterns have been identified in 143 isolates from patients infected in 33 epidemiologically unrelated incidents and two patterns have predominated, ST49:62 and ST49:62,1. These patterns were also common amongstS. typhimuriumphage-type 49 isolated from cattle and poultry; however ST49:62 was more common in bovines whereas ST49:62,1 predominated in poultry.S. typhimuriumphage-type 49 with a different profile pattern, ST49:62, 3, was responsible for a large outbreak in London in 1988 which was traced to mayonnaise made from eggs supplied by one producer. Plasmid profile typing can now be regarded as a method of supplementing phage typing in investigating outbreaks caused by this organism.

Brazil is the world’s third largest common bean (Phaseolus vulgaris L.) producer, and 60% of its population consumes this legume. Although organic farming is a sustainable alternative to nonorganic agriculture, its effect on chemical composition is still controversial. Therefore, the aim of this study was to investigate differences in the nutritional and phenolic compounds profiles between organically and nonorganically produced Brazilian black beans. Samples were obtained from the same harvest periods and from near geographical locations at metropolitan and coastal regions of Rio de Janeiro state, Brazil. No residues of 294 evaluated pesticides were detected in the samples. In both regions, organic beans had 17% fewer lipids, 10% less phytate and 20% more proteins when compared to nonorganic ones. Sixteen different phenolic compounds were identified as soluble and insoluble forms in black beans, with anthocyanins being the most abundant (on average, 66%). In both regions, soluble and total phenolic compounds contents in organic beans were consistently higher (on average, 25% and 28%, respectively) than in nonorganic ones. Our results show that organic farming improves the nutritional profile and increases the phenolic compounds content of black beans.

AbstractIncluding feed efficiency as a trait for selection has gained interest in the sheep industry because it can result in reduced feed inputs or improve stocking rates, both of which translate into increased profitability for the producer. It is of interest whether the feed efficiency status of a testing population of sheep could be predicted using rumen microbial profiles associated with divergent feed efficiency status in a training population of sheep. Two populations of ewes were fed the same diet, and each group was evaluated for feed efficiency. A total of 20 animals in the testing population were selected for prediction assessment using feed efficiency, including the 6 top-ranked, the 6 bottom-ranked, and 8 middle-ranked ewes stratified over the distribution. Rumen fluid samples were collected and DNA was extracted for sequencing. Using a rumen microbial profile associated with diverging feed efficiency created from the training population, multiple discriminant analyses were performed using the DISCRIM procedure of SAS to determine the probability of correctly identifying lambs in the testing population as low, medium, or high feed efficiency using their microbial profiles. A profile of 6 rumen microbial species were used to correctly (P < 0.001) predict all testing population ewes into their actual feed efficiency status. A regression analysis using the same microbial profile was used to predict feed efficiency values, which were strongly correlated (r = 0.71; P < 0.001) with actual feed efficiency values. These results indicate that specific rumen microbial species may play a role in feed efficiency, and that a microbial profile could be used to rank sheep for feed efficiency.

Summary This paper deals with the learning curve of a five-plus-year polymer-flooding pilot conducted in a mature waterflood that includes, for example, several works related to injector and producer wells and reservoir management. The scope of this paper is to describe the learning curve during the last 5 years rather than the reservoir response of the polymer-flooding technique; focus is on the aspects related to reduce cost per incremental barrel of oil for a possible extension to other waterflooded areas of the field. Diadema oil field is in the San Jorge Gulf basin in the southern portion of Argentina. The field is operated by CAPSA, an Argentinean oil-producer company; it has 480 producer and 270 injector wells (interwell spacing is 250 m on average). The company has developed waterflooding over more than 18 years (today, this technique represents 82% of oil production in the field) and produces approximately 1600 m3/d of oil and 40 000 m3/d of gross production (96% water cut) with 38 400 m3/d of water injection. The reservoir that is polymer-flooded is characterized by high permeability (average of 500 md), high heterogeneity (10 to 5,000 md), high porosity (30%), very stratified sandstone layers (4 to 12 m of net thickness) with poor lateral continuity (fluvial origin), and 20 °API oil (100 cp at reservoir conditions). Diadema's polymer-flooding pilot started in October 2007 on five water injectors (it includes 13 injectors today) with an injected rate of 1000 m3/d (today, 2000 m3/d). Polymer solution is made with produced water (15,000 ppm brine) and 1,500 ppm of hydrolyzed polyacrylamide polymer reaching 15- to 20-cp fluid-injection viscosity. Oil-production rate from the original “central” producers (wells that are aided with 100% of polymer injection) has increased 100% at the same time as average reduction in water cut is approximately 15%. The main aspects presented in this work are depth profile modification with crosslinked gel injected along with polymer, use of “curlers” to regulate injection in multiple wells with one injection pump without shearing the polymer, and an improved technology on producer wells with progressing-cavity pumps to decrease shut-in time and number of pump failures. The plan for the future is to extend this project to other areas with the acquired knowledge and to improve different aspects, such as water quality and optimization of polymer plant operation. These improvements will allow the company to reduce operating costs per incremental barrel of oil.

The previous study showed they have NRPS gene profiles that differ from each other. This study aims to determine the TLC Rf spots having inhibition activity against the growth of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922. The study was conducted using the 5 bacteria isolates, namely T19, T24, T25, T37 and T41. All isolates were fermented at room temperature for 14 days. Further the each broth culture was filtered and extracted using ethyl acetate. Components in the extract were separated by thin layer chromatography (TLC) with the mobile phase of chloroform-methanol (7: 3), followed by bioautography test against the S. aureus and E. coli to determine the chromatogram spots containing antibiotics. TLC results showed all isolates had different chromatogram profiles. The bioautography results showed that only isolate T25 can produce antibiotics against S. aureus. The antibiotic spot was at Rf 0.9 in the use of chloroform-methanol (7: 3) solvent system.

Objectives: This study aimed to identify the microbiological profile of various catheter tips, and multidrug resistance pattern of extended spectrum β-lactamase (ESBL) producing E. coli and Klebsiella spp. isolates.
Methods: A descriptive analysis of 263 catheter tip specimens processed for culture and antimicrobial susceptibility testing was carried out in B&B Hospital, Lalitpur. Five different types of catheter tips were analyzed for microbiological growth and antimicrobial susceptibility testing.
Results: Among catheter tips, the highest percentage of microbial growth was observed in tracheostomy tip. Monomicrobial growth was recorded in 82.9% catheter tips and polymicrobial growth was observed in 17.1% tip samples. Of 180 isolates, gram negative rods (76.6%) followed by yeast (19.4%) and gram-positive cocci (3.9%) were isolated. Gram negative Acinetobacter spp. (25%) and Pseudomonas spp. (23.3%) and gram-positive Enterococcus spp. (2.2%) were the most frequently isolated bacteria. However, carbapenam was the most effective antibiotic for both groups.
Conclusion: Of the total isolates tested, 61.4% were found to be multidrug resistant (MDR). Among gram negative rods, 22.2% E. coli and 27.3% Klebsiella spp. were confirmed as ESBL producer. It is recommended to apply standard protocol during insertion and removal of catheter which may help in managing nosocomial infection associated with catheters.

The Brazilian citriculture presents hegemony in the production and export of orange juice. The state of São Paulo is the largest national producer, accounting for 74% of the national production of this fruit. The State of Pará is responsible for 1.02% of the production of Orange in Brazil, of that amount the municipality of Captain Poço is responsible for 57% of the total produced. The objective of this research was to analyze the profile of different producers in compliance with the pesticide legislation. For the development of the work, a survey was carried out based on the Law of Agrochemicals—Law No. 7,802 of July 11, 1989 and the Law of Packaging—Law No. 9,974 of June 6, 2000, in the community of Cubiteua belonging to the municipality of Captain Poço/PA. The producers interviewed were chosen based on planted area and these were typified according to the amount of citrus planted. The percentage of respondents who know Federal Law 7,802/89, rectified by Law 9,974/00 and regulated by Decree No. 4,074/02, is equal to 8%. Both laws are not known to most producers, especially those with the smallest planted area, and as a consequence, they are not being met, leading to environmental, social, economic and human health problems.

Herein, we describe a case report of carbapenem-resistant Acinetobacter baumannii and Klebsiella pneumoniae isolates that were identified from the same patient at a Tertiary University Hospital Centre in Portugal. Antimicrobial susceptibility and the molecular characterization of resistance and virulence determinants were performed. PCR screening identified the presence of the resistance genes blaKPC-3, blaTEM-1 and blaSHV-1 in both isolates. The KPC-3 K. pneumoniae isolate belonged to the ST-14 high risk clone and accumulated an uncommon resistance and virulence profile additional to a horizontal dissemination capacity. In conclusion, the molecular screening led to the first identification of the A. baumannii KPC-3 producer in Portugal with a full antimicrobial resistance profile including tigecycline and colistin.

A Gram-stain-positive, spore-forming actinomycete strain (HKI0641T) was isolated from a soil sample collected in the Black Forest, Germany. During screening for antimicrobial natural products this bacterium was identified as a producer of the antibiotic telomycin. Morphological characteristics and chemotaxonomic data indicated that the strain belonged to the genus Micromonospora . The peptidoglycan of strain HKI0641T contained meso-diaminopimelic acid, and the fatty acid profile consisted predominantly of anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and C16 : 0. MK-10(H4), MK-10(H2) and MK-10 were identified as the major menaquinones. To determine the taxonomic positioning of strain HKI0641T, we computed a binary tanglegram of two rooted phylogenetic trees that were based upon 16S rRNA and gyrB gene sequences. The comparative analysis of the two common classification methods strongly supported the phylogenetic affiliation with the genus Micromonospora , but it also revealed discrepancies in the assignment at the level of the genomic species. 16S rRNA gene sequence analysis identified Micromonospora coxensis DSM 45161T (99.1 % sequence similarity) and Micromonospora marina DSM 45555T (99.0 %) as the nearest taxonomic neighbours, whereas the gyrB sequence of strain HKI0641T indicated a closer relationship to Micromonospora aurantiaca DSM 43813T (95.1 %). By means of DNA–DNA hybridization experiments, it was possible to resolve this issue and to clearly differentiate strain HKI0641T from other species of the genus Micromonospora . The type strains of the aforementioned species of the genus Micromonospora could be further distinguished from strain HKI0641T by several phenotypic properties, such as colony colour, NaCl tolerance and the utilization of carbon sources. The isolate was therefore assigned to a novel species of the genus Micromonospora , for which the name Micromonospora schwarzwaldensis sp. nov. is proposed. The type strain is HKI0641T ( = DSM 45708T = CIP 110415T).

Currently, there is a national concern regarding to the decrease of milkfish production from ponds in North Java due to a low quality of milkfish seed produced by small scale hatcheries in Bali, which is the main producer of milkfish seed. The quality of seed is strongly related to the quality of eggs (fertility), while quality of eggs produced depends on the management of brood stocks carried out by the hatcheries. Growth rate and growth hormone profiles are some of the biological aspects that could be used as a basis/benchmark to evaluate quality level of milkfish seed reared in ponds. The aim of this experiment was to evaluate growth rate and growth hormone profile performance between selected G-2 seed and small scale hatcheries seed as control population the growth rate. Research on grow-out of milkfish seed was conducted at the IMRAD ponds facility in Pejarakan, using milkfish seed produced by small scale hatcheries as well as selected second-generation (G-2) seed, each with the density of 5000 seed/pond (1 pond=0.5 ha). The seeds were fed with dry pellet and reared for 5 – 6 months. The results showed that the seed produced with standard operational procedure (SOP) by small scale hatcheries were having longer (F hit. = 13.68 > F tabel 1%) and heavier body washt (F hit. = 18.98 > F tabel 1%) better than selected G-2 seed and small scale hatcheries seed without SOP with high growth hormone concentration (F hit. = 4.95 > F tabel 5%).

The aims: Screen for the Extended-Spectrum Beta-Lactamase producing Klebsiella pneumonia from urinary tract infection UTI patients phenotypically and molecularly, also testing different sizes of silver nanoparticles as antibacterial for the resistance isolates. Methodology: Vitek Extended-Spectrum Beta-Lactamase test , molecular confirmed ESBL-producing isolates were checked by PCR for the presence of AmpC and blaCTX-M genes. Flat well microtiter plates were used for packing of antibacterial activity of silver nanoparticles . This study included 85 urine samples were collected from patients that admitted to the "Rizgary Hospital" in Erbil province from 15 June to 15 December 2018. Antibiotic sensitivity test of all isolates to (Ampicillin, Ampicillin/sulbactam Cefazolin, Ceftazidime Ceftriaxone, Cefepime, Imipenem, Nafcillin and Nitrofurantoin )antibiotics were tested by the disc-agar method as standardized by the National Committee for Clinical laboratory Standards (2006).Results: Out of 51 tested isolates of Klebsiella pneumonia, 11 (21.6%) were Extended-Spectrum Beta-Lactamase Producers. Their antibiotic resistance profile showed the rate of resistance isolates was (100%) to Ampicillin, Cefazolin, Ceftazidime and Ceftriaxone and ( 90%) to Cefepime .In addition the susceptibility to Imipenem was (72.7%) of isolates. The bands of the AmpC and bla CTX-M genes was noted in (42.9%) samples and the remain samples (57.1 %)were negative for both genes. The Minimum Inhibitory Concentration during incubation of Non ESBL producer - ESBL producer isolates in series concentrations of silver nanoparticles size (20 nm) was between (625 -2500) µg/ml and for size (90 nm), it was (1250) µg/ml for non ESBL producer and not affected ESBL producer isolates .The increased percentage rates of β-lactamase producing Klebsiella species were seen which was considered as an alarm, due to limitation in treatment options for UTI. It was appeared that Imipenem currently is the main available antibiotic for UTI treatment as a drug of choice. It was noticed that different sizes of silver nanoparticles showed antibacterial activity for ESBL producing isolates.

The eicosanoid profiles, sites of production, and response to bradykinin stimulation were determined in rabbit ileum and its various components by radioimmunoassay of various prostanoids and 5-lipoxygenase products in the incubation media. The profile of eicosanoid synthesis and secretion by the epithelial cell fraction was PGF2 alpha greater than 6-keto-PGF1 alpha greater than dihydro-keto-PCM = PGE2 greater than TxB2 much greater than 5-HETE greater than LTB4 and by the deepitheliated ileum was PGE2 = 6-keto-PGF1 alpha greater than PGF2 alpha greater than dihydro-keto-PGM greater than TxB2 much greater than LTB4 greater than 5-HETE. PGD2 was not sought in these studies. Rates of eicosanoid production by the deepitheliated ileum were over 200 times that of the epithelial cells. The epithelial cells accounted for 67% of the protein but only 0.2% of the PGE2 produced, while the lamina propria and submucosa contained only 12-30% of the protein but produced 80-90% of the PGE2. Bradykinin (1 microM), A23187 (10 microM), arachidonic acid (20 microM), and melittin (0.7 microM) stimulated PGE2 and 6-keto-PGF1 alpha production by 200% in deepitheliated (or subepithelial) ileum, but bradykinin failed to stimulate production of any eicosanoid by the epithelial cell fraction. Thus the subepithelium (predominantly the lamina propria) is the major eicosanoid producer of rabbit ileum and is the major site of bradykinin-stimulated eicosanoid synthesis and secretion. Eicosanoids released from subepithelial components may be important regulators of epithelial function.

Peanut cultivation has been used as a rotation crop in sugarcane renewal areas in São Paulo, state, Brazil. This practice guarantees agronomic and economic benefits to the region in a way complementary to the sugarcane crop. Small- and medium-sized rural producers have specialized in the cultivation of peanuts in the
of renewal sugarcane areas, with production mainly occurring via a lease contract system. Thus, the objective of this study is to analyze the economic viability of commercial and productive operations associated with the peanut cultivation in leased areas. From a delimitated production profile modal, it was possible to analyze economic viability by triangulating secondary and primary information for peanut cultivation in Jaboticabal, the city of greatest production of this oil-giving seed in Brazil. Using Net Present Value, Internal Rate of Return, Return on Investment and Point of Equilibrium techniques, it was possible to show that the peanut crop is operationally feasible. However, financial and economic viability only occurred when leases cost equal or less
than 50 sacks per hectare and when the producer was able to work with an area equal to or greater than 91 hectares (the break-even point). These results bring new economic information, supplementing that already in literature and provides data necessary for the rural producer to plan of production and size of investment.

The ability of Staphylococcus epidermidis to produce virulence factors, such as biofilm, added to its increased resistance to antimicrobials can cause infections that are difficult to treat. Many staphylococcal virulence factors are under the control of the accessory gene regulator (agr). The objective of this study was to establish the agr locus and susceptibility of biofilm-producing S. epidermidis specimens to antimicrobial agents, through PCR reactions, reverse transcription polymerase chain reaction (RT-PCR), and the determination of minimum inhibitory concentration (MIC), and to analyze the clonal profile of 300 strains isolated from blood culture specimens from inpatients at a University Hospital in Brazil, over a 20-year period by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) techniques. The ica operon expression was shown in 83.6% strains, bhp gene in 11.5%, and aap gene in 32.8%. Oxacillin resistance was detected in 90.1%, while 4.9% showed tigecycline resistance, and intermediate resistance to quinupristin/dalfopristin was identified in 0.4%. Clonal profile determination showed 11 clusters, with the ST2 type determined as the major cluster. The S. epidermidis biofilm producer demonstrated a predominance of agr I locus, oxacillin resistance, and SCCmec III as well as the potential dissemination of pathogenic clones in hospital settings over long periods.

Summary Field-scale rate optimization problems often involve highly complex reservoir models, production-and-facilities related constraints, and a large number of unknowns. These factors make optimal reservoir management through rate- and flood-front control difficult without efficient optimization tools. Some aspects of the optimization problem have been studied before mainly using an optimal control theory. However, the applications to date have been rather limited to small problems because of the computation time and the complexities associated with the formulation and solution of adjoint equations. Field-scale rate optimization for maximizing waterflood sweep efficiency under realistic field conditions has remained largely unexplored. This paper proposes a practical and efficient approach for computing optimal injection and production rates, thereby managing the waterflood front to maximize sweep efficiency and delaying the arrival time to minimize water cycling. Our work relies on equalizing the arrival times of the waterflood front at all producers within selected subregions of a waterflood project. The arrival-time optimization has favorable quasilinear properties, and the optimization proceeds smoothly even if our initial conditions are far from the solution. Furthermore, the sensitivity of the arrival time with respect to injection and production rates can be calculated analytically using a single-flow simulation. This makes our approach computationally efficient and suitable for large-scale field applications. The arrival time optimization ensures appropriate rate allocation and flood-front management by delaying the water breakthrough at the producing wells. Several examples are presented to support the robustness and efficiency of the proposed optimization scheme. These include several 2D-synthetic examples for validation purposes and a 3D field application. In addition, we demonstrate the potential of the approach to optimize the flow profile along injection/production segments of horizontal-smart wells. Introduction Waterflooding is by far the most commonly used method to improve oil recovery after primary depletion. In spite of its many favorable characteristics, reservoir heterogeneity—particularly permeability contrast—can have an adverse impact on the performance of waterflooding. The presence of high-permeability streaks can severely reduce the sweep efficiency, leading to an early water arrival at the producers and bypassed oil. Also, an increased cost is associated with water recycling and handling. One approach to counteract the impact of heterogeneity and improve waterflood sweep efficiency is optimal rate allocation to the injectors and producers (Asheim 1988; Sudaryanto and Yortsos 2001; Brouwer et al. 2001; Brouwer and Jansen 2004; Grinestaff 1999; Grinestaff and Caffrey 2000). Through optimal rate control, we can manage the propagation of the flood front, delay water breakthrough at the producers, and also increase the recovery efficiency. Previous efforts to optimize waterflooding relied on optimal control theorem to allocate injection/production rates for fixed well configurations. Asheim (1988) investigated the optimization of waterflood based on maximizing net present value (NPV) for multiple vertical injectors and one producer where the rate profiles change throughout the optimization time. Sudaryanto and Yortsos (2001) used maximizing the displacement efficiency at water breakthrough as the objective for the optimization with two injectors and one producer. The optimal injection policy was found to be bang bang type. That is, the injectors were operated only at their extreme values—either at the maximum allowable injection rate or fully shut. The optimization then involved finding the switch time between the two injectors to ensure simultaneous water arrival at the producing well. Brouwer et al. (2001) studied the static optimization of waterflooding with two horizontal smart wells containing permanent downhole well-control valves and measurement equipment. The static optimization implies that the flow rates of the inflow-control valves (ICVs) along the well segments were kept constant during the waterflooding process until the water arrived at the producer. Various heuristic algorithms were utilized to minimize the impact of high-permeability streaks on the waterflood performance through rate control. The results indicated that the optimal rate allocation can be obtained by reducing the distribution of water-arrival times at various segments along the producer. Subsequently, Brouwer and Jansen (2004) extended their work to dynamic optimization of waterflooding with smart wells using the optimal control theory. The optimization was performed on one horizontal producer and one horizontal injector. Each well is equipped with 45 ICVs. The objective was to maximize the NPV, and it was achieved through changing the rate profile along the well segments throughout the optimization period. Both rate-constrained and bottomhole-pressure-constrained well conditions were studied.

Mangifera indica L. belongs to the family of Anacardiaceae and is an important fruit from South and Southeast Asia. India, China, Thailand, Indonesia, Pakistan, Mexico, Brazil, Bangladesh, Nigeria, and the Philippines are among the top mango producer countries. Leaves of the mango plant have been studied for their health benefits, which are attributed to a plethora of phytochemicals such as mangiferin, followed by phenolic acids, benzophenones, and other antioxidants such as flavonoids, ascorbic acid, carotenoids, and tocopherols. The extracts from mango leaves (MLs) have been studied for their biological activities, including anti-cancer, anti-diabetic, anti-oxidant, anti-microbial, anti-obesity, lipid-lowering, hepato-protection, and anti-diarrheal. In the present review, we have elaborated on the nutritional and phytochemical profile of the MLs. Further, various bioactivities of the ML extracts are also critically discussed. Considering the phytochemical profile and beneficial effects of the MLs, they can be used as a potential ingredient for the development of functional foods and pharmaceutical drugs. However, more detailed clinical trials still needed to be conducted for establishing the actual efficacy of the ML extracts.

This paper shows a report of over three years of intensive work on application of a 3-axis anisotropic magnetoresistive sensor with I2C interface for measurement of magnetic flux density distribution of automotive wheels. The work was undertaken to answer the question of whether is a possibility to effectively apply low-cost magnetic sensors with serial interface to measure the magnetic field surrounding the automotive wheel or tire. Two measurement techniques were discussed: Magnetic profile (1D) and magnetic surface measurement (2D) over tread, and also gear associated with the sensor, as well as its design, layout, operation, and control technique during (1D) and (2D) measurements. Three experiments were performed to asses accuracy and repeatability concerning component and resultant magnetic circumferential profiles and also magnetic surface. Differences between measurement outcomes in experiment were assessed. The results show that accuracy and repeatability lays below maximum admissible uncertainty declared by the producer. This proves directly that there is no measurable influence of motors, gear, operation, or measurement procedure on results obtained by magnetic sensors, and indirectly, that the assumed requirements regarding gear design and parameters are correct, and measurement of magnetic flux density distribution of automotive wheels and tires using (1D) and (2D) techniques is possible using a 3-axis anisotropic magnetoresistive sensor with I2C interface.

This article considers whether contracts to purchase ‘haunted’ objects are legally enforceable under Australian contract law. ‘Dybbuk boxes’, and related paraphernalia said to be possessed by spirits, are becoming increasingly popular on online shopping sites and as tourist attractions following recent high-profile incidents involving celebrities such as American rapper and record producer Post Malone. This article suggests that the enforceability of contracts for the sale of haunted items such as dybbuk boxes is dubious at best, and that the countless number of such contracts that have been concluded may be subject to legal challenge.

Testo completoAbstract (sommario):
Virgin coconut oil (VCO) can be prepared with or without heat. Fermentation and centrifuge processes can be done without the use of heat (cold process), while expelling involves heat due to friction. Volatile organic compounds (VOCs) from VCO samples prepared using these three methods were collected using solid phase microextraction (SPME) and analyzed using gas chromatography–mass spectrometry (GC-MS). Twenty-seven VCO samples from nine VCO producers were analyzed. The VOCs from refined, bleached, and deodorized coconut oil (RBDCO) were also obtained for comparison. Fourteen compounds were found to be common in more than 80% of the VCO samples analyzed. These included: Acetic acid; C6, C8, C10, C12, and C14 fatty acids, and their corresponding delta-lactones; and C8, C10 and C12 ethyl carboxylates. Fourteen minor VOCs were likewise detected which can be grouped into five types: Carboxylic acids (formic acid, butanoic acid, benzoic acid, and pentadecanoic acid), ketones (acetoin, 2-heptanone), an alcohol (ethanol), aldehydes (acetaldehyde, hexanal, benzaldehyde), esters (ethyl acetate, methyl tetradecanoate), and hydrocarbons (n-hexane and toluene). Five pyrazines were detected in expeller VCO. Various hydrocarbons from C5 to C14 were noted to be higher in old RBDCO and VCO samples. There were variations in the VOCs within each VCO process as each producer used different processing times, temperatures, and drying procedures. Principal components analysis (PCA) was able to group the samples according to the process used, but there were overlaps which may be due to variations in the specific procedures used by the manufacturers. These results may help VCO manufacturers control their production processes.
