High hydrostatic pressure (HHP) treatment is a non-thermal processing technology, which is widely used in the food processing field at present. In this study, the effects of HHP treatment (100~500 MPa for 5 min) on the physicochemical properties, texture parameters, and volatile flavor compounds of oysters were investigated. The results showed that HHP treatment increased the water content while reducing the crude protein and ash content of the oyster. Texture parameters showed that HHP treatment improved the hardness, springiness, chewiness, and cohesiveness of oysters, compared with the control group. In addition, the saturated fatty acid (SFA) content was slightly increased after HHP treatment, while the difference in monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) content was not significant. Furthermore, HHP increased hexenoic aldehyde, 2,4-heptadienal, 1-octene-3-ol, and 2-octen-1-ol and decreased the contents of 3. 6-nadien-1-ol, 3-octanone, and 2-undecanone, suggesting that HHP might inhibit the fishiness of oyster and showed a positive effect on its flavor. Based on the above results, HHP improved the edible qualities such as texture properties and volatile flavor of oysters. This meets the requirements of consumers on the edible quality of seafood and provides new ideas for the development of seafood.

The aim of this study was to determine the effect of different ratios of low protein flour to oyster mushroom (Pleurotus sajor-caju) powder on the physicochemical properties and sensory acceptability of edible tablespoon. Fresh grey oyster mushroom was dried in a convection oven at temperature of 55.0˚C ± 2.0˚C for 20 h prior to the grinding process. The low protein flour (LPF) was then incorporated with oyster mushroom powder (OMP) at different ratios of 100:0, 96:4, 92:8, 88:12 and 84:16, before being with vegetable oil, sugar, egg white and water in formulating the edible tablespoon. The proximate analyses were carried out in triplicate for calorie content, colour profile, hardness value and morphological structure of edible tablespoon. This study revealed that with decreasing LPF and increasing OMP in the formulation, the ash content (1.24% to 1.92%), crude fat content (8.98% to 10.40%) and fiber content (0.13% to 1.24%) were observed to have increased as well as the hardness value (2042.03g to 2844.57g) and pore’s size of the morphological structure of edible tablespoon. However, the carbohydrate content (78.64% to 75.56%) significantly decreased (p>0.05) together with L* value (from 68.47 to 61.71) when the decrease was in the the percentage of LPF and an increase the percentage of OMP. The calorie content, moisture content and protein content of edible tablespoon were not significantly (p>0.05) affected by different ratios of LPF to OMP. The edible tablespoon formulated with up to 8% of OMP was accepted by the sensory panelists but further increase in OMP addition significantly decreased the degree of likeness in terms of colour, odour, taste and overall acceptability of edible tablespoon. This study suggested that oyster mushroom edible tablespoon could be potential alternative disposable cutlery which will help to reduce the use of huge amount of non-biodegradable materials for environmental conservation.

ABSTRACTThe microbiological quality of oysters reflects the microbiological quality of their habitats because they are filter feeders. The objective of this study was to assess the bacterial composition of the edible oyster Crassostrea rhizophorae in urban and preserved estuaries. Particularly, we assessed the presence of pathogenic bacteria, investigated antibiotic susceptibility in bacterial isolates, and quantified β-lactam antibiotic resistance genes (blaTEM, blaSHV, and blaKPC) via quantitative PCR of oyster DNA. Our results detected total coliforms, Escherichia coli, and enterobacteria in the oysters from urban estuaries, which is indicative of poor water quality. In addition, our detection of the eaeA and stxA2 virulence genes in 16.7% of E. coli isolates from oysters from this region suggests the presence of multiantibiotic-resistant enteropathogenic and enterohemorrhagic E. coli strains. During periods of low precipitation, increased contamination by E. coli (in winter) and Vibrio parahaemolyticus (in autumn) was observed. In contrast, cultivated oysters inhabiting monitored farms in preserved areas had low levels of bacterial contamination, emphasizing that oyster culture monitoring enhances food quality and makes oysters fit for human consumption. Distinct antibiotic resistance profiles were observed in bacteria isolated from oysters collected from different areas, including resistance to β-lactam antibiotics. The presence of the blaTEM gene in 91.3% of oyster samples indicated that microorganisms in estuarine water conferred the capability to produce β-lactamase. To our knowledge, this is the first study to directly quantify and detect β-lactam antibiotic resistance genes in oysters. We believe our study provides baseline data for bacterial dynamics in estuarine oysters; such knowledge contributes to developing risk assessments to determine the associated hazards and consequences of consuming oysters from aquatic environments containing pathogenic bacteria that may possess antibiotic resistance genes.

As filter-feeding animals farmed in water bodies exposed to anthropogenic influences, oysters can be both useful bioremediators and high-risk foodstuffs, considering that they are typically consumed raw. Understanding the dynamic of bacterial and viral load in Pacific oyster (Crassostrea gigas) tissues, hemolymph, outer shell surface biofilm, and farming water is therefore of great importance for microbiological risk assessment. A one-year survey of oysters collected from a class B production area (Canal de Mira, on the Portuguese western coast) revealed that these bivalve mollusks have a good depurating capacity with regard to bacteria, as Salmonella spp. and viable enterococci were not detected in any oyster flesh (edible portion) samples, despite the fact that these bacteria have regularly been found in the farming waters. Furthermore, the level of Escherichia coli contamination was clearly below the legal limit in oysters reared in a class B area (>230–≤4600 MPN E. coli/100 g). On the contrary, norovirus was repeatedly detected in the digestive glands of oysters sampled in autumn, winter, and spring. However, their presence in farming waters was only detected during winter.

Oyster and mussel farming along the coasts and the desire to increase fishing revenue have created a boom in these types of farms. An experiment on culture of edible oyster (Saccostrea cucullata) and green mussel (Perna viridis) was performed at Gangamoti estuary in Kuakata, Bay of Bengal coast of Bangladesh from December 2021 to March 2022 to find out the appropriate culture method of the oyster, S. cucullata and green mussel, P. viridis. Initially, the average shell heights of S. cucullata and P. viridis were 8.8±1.62 and 6.9±1.89 cm, respectively; where average weights were153.4±13.23 and 84.78±11.78 g, respectively. After the culture period, oysters shell height and weight grew up to 9.1±1.98 cm and 163.2±12.54 g, respectively in rectangular basket and 8.9±1.45 cm and 157.2±11.31 g, respectively in velon screen bag. In case of oysters, the rectangular basket and velon screen bag displayed the minor progress in specific growth rate, 0.09±0.01 and 0.07±0.03, respectively. But green mussels did not show any growth rate. Oysters cultured in rectangular basket showed total mortality at day-90 and velon screen bag at day-75. Green mussels showed 100% mortality within 21 days of culture. Our experiment was the first attempt to culture these two mollusks in the Kuakata coast of Bangladesh. However, further intensive researches would be required to evaluate the culture feasibility of these two mollusks’ species in the Kuakata coast of Bangladesh.

AbstractThe aim of this study was to examine the content of chemical elements in the dried fruiting bodies of edible wood decaying fungi such as Honey mushrooms (Armillaria mellea), Shiitakes (Lentinus edodes) and Oyster mushrooms (Pleurotus ostreatus). Powdered samples of fungi were mineralized in a microwave digestion. Twenty-one (21) chemical elements were detected in the plasma of the device ICP-MS AGILENT 7500c by accredited methods with the aid of calibration curves. The content of individual elements varied within a considerable range. The highest contents of K, Mn, Cu and Cd were found in the fruiting bodies of Honey mushrooms (Armillaria mellea). Shiitakes (Lentinus edodes) had the highest content of B and Mo. Significant differences were found in the content of elements in the Oyster mushrooms (Pleurotus ostreatus) from Slovakia, Hungary and China. The highest content of Al was found in the Oyster mushrooms (Pleurotus ostreatus) from Hungary. The Chinese oysters had a maximum contents of Ca, Mg, Co, Pb, As and U. The Oyster mushrooms (Pleurotus ostreatus) from Lemešany (Slovakia) had the highest contents of Na, Zn, Fe, Se, Ag, Hg and Cr. The difference of chemical element content could be influenced by the genotype of the fungus and by the composition of substrate on which mushroom grow up.

Viral contamination of edible bivalves is a major food safety issue. We studied the virucidal effect of a cold atmospheric plasma (CAP) source on two virologically different surrogate viruses [a double-stranded DNA virus (Equid alphaherpesvirus 1, EHV-1), and a single-stranded RNA virus (Bovine coronavirus, BCoV)] suspended in Dulbecco’s Modified Eagle’s Medium (DMEM). A 15 min exposure effectuated a statistically significant immediate reduction in intact BCoV viruses by 2.8 (ozone-dominated plasma, “low power”) or 2.3 log cycles (nitrate-dominated, “high power”) of the initial viral load. The immediate effect of CAP on EHV-1 was less pronounced, with “low power” CAP yielding a 1.4 and “high power” a 1.0 log reduction. We observed a decline in glucose contents in DMEM, which was most probably caused by a Maillard reaction with the amino acids in DMEM. With respect to the application of the virucidal CAP treatment in oyster production, we investigated whether salt water could be sanitized. CAP treatment entailed a significant decline in pH, below the limits acceptable for holding oysters. In oyster slurry (a surrogate for live oysters), CAP exposure resulted in an increase in total nitrogen, and, to a lower extent, in nitrate and nitrite; this was most probably caused by absorption of nitrate from the plasma gas cloud. We could not observe a change in colour, indicative for binding of NOx to haemocyanin, although this would be a reasonable assumption. Further studies are necessary to explore in which form this additional nitrogen is deposited in oyster flesh.

Rock oysters of the genus Saccostrea are the dominating group of filter-feeding communities on rocky beaches worldwide. The edible rock oyster (Saccostrea cucullata) is used as food and fish bait along the Indian coast. Morphometric analyses of S. cucullata from Baindur, Karnataka (India) were performed from June 2010 to May 2011, aiming to establish relationships between length and weight (total weight, shell weight, meat wet weight and meat dry weight). Morphometric relationships between length (L)-breadth (B) and length (L)-width (W) were B = 6.4952 + 0.4619 L and W = 3.1806 + 0.3276L, respectively. The equations of the length (L)-total weight (TW), length (L)-shell weight (SW), length (L)-meat wet weight (WW) and length (L)-meat dry weight (DW) were TW = 0.001227L2.3973, SW = 0.001165L2.3164, WW = 0.000037L2.1327 and DW = 0.000030L2.3289, respectively. The allometric growth pattern revealed changes in shell shape and weight variation throughout ontogeny in rocky habitats. The condition index and meat yield of S. cucullata exhibited seasonality, with higher values recorded during the periods post-monsoon and pre-monsoon.

The present work investigated the effects of replacing the fat in meatballs with enoki, brown beech, shiitake, white oyster, brown, or king oyster mushrooms on the physicochemical and sensorial characteristics of the reduced-fat meatballs. The water holding capacity of the reduced-fat meatballs increased significantly (14.4 - 36.5%) in parallel to a significant increase in the moisture (3.3 - 5.6%) and protein (4.1 - 7.5%) contents, with a decrease in fat (16.3 - 86.3%) content as compared to the control. No differences were found for the cooking yield and texture properties of the samples, except for the king oyster mushroom which reduced the hardness of the reduced-fat meatballs. The redness of the reduced-fat meatballs was comparable with the control, but reduced in yellowness and lightness. Most of the reduced-fat meatballs had better sensory characteristics as compared to the control, in particular, the meatballs with shiitake mushroom. In conclusion, all the mushrooms tested have the potential to be used as a full fat replacer in meatballs, except for king oyster mushroom which reduced the texture quality of the reduced-fat meatballs.

Oyster mushrooms are economical and most easily grown of all cultivated edible mushrooms. The crop has a range of varieties, differing in form, colour, texture and odor, which can be cultivated throughout the year under a diverse agro-climatic conditions. Three different oyster mushroom species viz., Hypsizygus ulmarius (var. CO2), Pleurotus eous (var. APK1) and Pleurotus florida (var. PF) along with three cropping rooms of varied temperatures was used for the study. Among the different cropping rooms, thatched shed with a temperature of 23o C recorded a highest yield of 748g, 712 and 673 g per 500 g of substrate by PF, CO 2 and APK 1 respectively than AC room and Concrete room. The temperature of the cropping room is inversely proportional to the yield of oyster mushroom. Hence, the thatched shed was best suited for oyster mushroom cultivation, which was both economic and easy to use.

This research aims to reduce solid waste, resource depletion, and material toxicity in the footwear industry. Mycelium, the root structure of mushrooms, binds together substrate materials as it grows, offering opportunities for composite development. Mycelium composites were developed using edible mushroom species alongside other natural materials. The 4 × 2 experiment tested four mushroom species (reishi, oyster, king oyster, and yellow oyster) and two fabric levels (with or without a natural fabric mat). Scanning electron microscopy images confirmed mycelium growth within the composite and around the substrates. Two-way analysis of variance tests found that both species and fabric significantly affected the density, and the species significantly affected the compressive strength. A positive and significant linear relationship was found between density and compressive strength, with higher density leading to higher compressive strength. The compressive strength of the mycelium composites, especially those made from king oyster mycelium, provides opportunities for renewable and biodegradable footwear inputs.

Oyster (Crassostreairedalei) are edible bivalve mollusk that contains nutrients that could enhance the nutritional value of dairy products such as ice cream. This study was conducted to determine the microbial and sensorial quality of ice cream fortified with oyster puree at 0% 5%, 10% and 15% concentration during 4 weeks’ frozen storage period. Based on the sensory evaluation results, treatment 2 (10%) obtained the highest overall acceptance mean score of 8.50 (like extremely), but showed no significant difference (p>0.05) with other treatments. The addition of oyster puree did not affect the sensory attributes and the overall acceptability of the products. All treatments were still acceptable on week 4 in terms of sensory attributes. For the basis of microbial analysis, all treatments revealed to have an acceptable microbial count that is below the standard limit of 100,000 CFU/ml (5 log CFU/ml) from week 0 to week 4. Development of ice cream fortified with oyster puree is feasible to increase its nutritional value.

Potential spat collectors and suitable culture sites were investigated for the development of edible oyster culture from June to December 2019 at three study sites (Moheshkhali, the Jeti of Nuniarchora, and Sonadia) of Cox’s Bazar coast of Bangladesh. Four types of collectors such as oyster shell, earthen pot, kortal (windowpane oyster shell) and tiles were investigated. On site sampling of water quality parameters and number of spats on each collector were done at 15-days interval following standard methods. Results indicated insignificant difference (P > 0.05) in temperature, salinity, dissolved oxygen and pH, while significant difference (P < 0.05) in total dissolved solids, total suspended solids and Chl-a content of the water among the study locations. However, these parameters were in suitable range for growth and spawning of oyster. Results also indicated spat recruitment was significantly influenced by the types of collectors and study locations with significantly (P < 0.05) higher spat were recruited in Tiles. Tiles were also found to facilitate with an advantage of recycling of this collector. The location in interaction with polluting materials such as total dissolved solids and total suspended solids had a significant effect on spat recruitment rate and therefore, Sonadia was the most suitable location for spat recruitment. This study site can also be used as a suitable location for the development of oyster culture in the cost of Bay of Bengal, Bangladesh based on its environmental characteristics. Bangladesh J.

This research studies the possible use of some of Iraq's local agricultural wastes as growth substrates for producing the edible oyster mushroom (Pleurotus eryngii). The biological process of growing and producing edible mushrooms is a bioconversion of organic wastes to bioprotein (mycoprotein). Therefore, this study aims to investigate nine different substrates from plant residues. The three primary substrates are typical viz date palm waste (Phoenix dactylifera), maize cob (Zea mays) and cane (Phragmites communis), with two types of additional enrichment, i.e., rice husks (Oryza sativa) and corn seeds husks (Zea mays), and without further enrichment (control). The experiment was randomly distributed according to Randomized Complete Design (RCD), with three replicates. The less crop cycle period (day) which in Treatments T7 and T8 (30.33, 31.67 days) when T2 (100%Corncobs), T1 (100%Waste of Date palm), T7 (80%Waste of the date palm with 20%Corn husks) and T8 (80% Corncobs with 20%Corn husks) provide the crest mushrooms yield arrived 293.0 280.7, 268.7 and 264.0 g kg-1 substrate respectively.

Oyster mushrooms (Pleurotus Ostreatus), such as white mushroom, chinese mushroom, and warm mushroom, is one type of edible mushrooms. Oyster mushroom cultivation is usually done at the mushroom house (kumbung) which is mostly made of bamboo. Oyster mushrooms can grow optimally by controlling the temperature and humidity in the kumbung. Kumbung environment conditioning is usually done manually by spraying water on the planting medium every 8 hours. But this is perceived as ineffective and requires high effort. For this reason, we need a technology that can monitor as well as control the environmental conditions inside the kumbung automatically and remotely. This paper describes the design of a system to monitor and control the temperature and humidity in the kumbung for oyster mushroom cultivation based on IoT (Internet of Things). This system is developed consisting of five parts, i.e sensor modules, microcontrollers, data loggers, actuators, and monitoring and control interfaces. The main result of this study is a remote monitoring and control of environmental conditions for oyster mushroom cultivation. The data of monitoring, in the form of temperature and humidity, are saved to the data logger and can be downloaded in the format (.csv). The system works functionally in accordance with the expected specifications, both in terms of sensor readings and actuator controlling.

Abstract. The rapidly intensifying process of ocean acidification (OA) due to anthropogenic CO2 is not only depleting carbonate ions necessary for calcification but also causing acidosis and disrupting internal pH homeostasis in several marine organisms. These negative consequences of OA on marine calcifiers, i.e. oyster species, have been very well documented in recent studies; however, the consequences of reduced or impaired calcification on the end-product, shells or skeletons, still remain one of the major research gaps. Shells produced by marine organisms under OA are expected to show signs of dissolution, disorganized microstructure and reduced mechanical properties. To bridge this knowledge gap and to test the above hypothesis, we investigated the effect of OA on juvenile shells of the commercially important oyster species, Magallana angulata, at ecologically and climatically relevant OA levels (using pH 8.1, 7.8, 7.5, 7.2). In lower pH conditions, a drop of shell hardness and stiffness was revealed by nanoindentation tests, while an evident porous internal microstructure was detected by scanning electron microscopy. Crystallographic orientation, on the other hand, showed no significant difference with decreasing pH using electron back-scattered diffraction (EBSD). These results indicate the porous internal microstructure may be the cause of the reduction in shell hardness and stiffness. The overall decrease of shell density observed from micro-computed tomography analysis indicates the porous internal microstructure may run through the shell, thus inevitably limiting the effectiveness of the shell's defensive function. This study shows the potential deterioration of oyster shells induced by OA, especially in their early life stage. This knowledge is critical to estimate the survival and production of edible oysters in the future ocean.

Greece exhibits the lowest seafood per capita consumption amongst European Mediterranean countries, and the investigation of consumer attitudes to new seafood products would bridge the gap among producers and consumers by promoting the vertical integration of the supply chain. However, limited information exists about consumer preferences for bivalves in the Mediterranean and for wild bivalves in particular. The present study aims to investigate, for the first time, consumers’ attitudes towards the purchase and consumption of bivalves, and more specifically, towards the edible pearl oyster Pinctada imbricata radiata, in the Greek shellfish market. Adult participants from the entire country completed a questionnaire covering the basic marketing aspects of bivalve and pearl oyster consumption, such as choice, purchase, reasons for consuming bivalves, confidence in product’s hygiene certification, media influence, etc. Data analysis included uni- and multi-variate statistics to examine the possible relations between the consumers’ demographics and socio-economic characteristics, and bivalve marketing aspects. Results showed that the majority of Greek consumers chooses traditional shellfish shops for purchasing pearl oysters, prefers a certification of quality, and trusts the confirmation provided by the veterinary authorities. Consumers’ attitudes vary considerably according to their demographics and socio-economic characteristics. Multivariate models revealed that the married, highly educated consumers that live in urban places were more reluctant to try new shellfish products and to accept an innovative way of market supply. The results reflect the positive attitude of Greek consumers towards the consumption of pearl oyster, a fact that would be helpful for decision makers in the planning of production, which in turn would promote bivalve consumption in the Greek shellfish market.

The present study investigates through an integrated survey, for the first time in Greek shellfish market, the marketing distribution towards a new edible shellfish product that of the non-indigenous pearl oyster Pinctada imbricata radiata. The survey conducted through personal interviews on sector entrepreneurs/staff of the supply (i.e., shellfish producers, wholesalers, fishmongers, owners of restaurants). Internet-based quantitative research was also conducted to explore the market supply of the pearl oyster covering all nine regional units of Greece. The market for pearl oyster seems to be there as a substitute of the major commercial species in seasons of shortages. There is a specimen mislabeling throughout Greece, thus, extraction of significant information about the market supply of pearl oyster is deficient. Further knowledge on the bivalve shellfish value chain is needed, to define how the wild and the farmed species (mussels) interact in the market and in the distribution channels, toward a product-easy to use in the supply chain and friendly to the consumer. Findings also raises additional concerns as a priority for conservation, and the current practices do not satisfy the Common Fisheries Policy in terms of traceability.

One thousand two hundred and fifty land snails were divided randomly among 25, 1.5-m × 0.9-m × 1.5-m cages wrapped in a nylon screen and chicken wire to prevent the snails from escaping and to protect them from predators. The cages were placed in a shaded area on the southeastern edge of a white clover field and randomly divided into five nutritional treatments with each treatment replicated five times. The snails were fed with natural vegetation, lettuce and oyster shells, lettuce alone, oat bran, or white clover in treatments 1, 2, 3, 4, and 5, respectively. A digestibility trial on lettuce and white clover was also carried out. The snails gained significantly (P < 0.05) more weight when fed with the lettuce and lettuce plus oyster shells than the other treatments. The weight gains for the white clover and natural vegetation were intermediate among the diets. The death rate was approximately 5.1 ± 0.3% in each treatment with the exception of the oat bran diet (66 ± 5%). The digestibilities of lettuce and white clover dry matter were 83.1 ± 1.3% and 82.5 ± 1.5%, respectively, and were not significantly different (P > 0.05). It was concluded that edible land snails can be raised outside during the summer under the environmental conditions of Nova Scotia if fed with diets 1, 2, 3, or 5.

Mushroom cultivation is increasing day by day in Chhattisgarh as well as India and is an important dietary food for rural people. The protein nature of the cereal-based diet can be improved by fortification. Edible mushrooms are rich in protein, carbohydrates, minerals, and other nutritional compounds. Value additions of mushrooms in the form of powdered biscuits, cake etc, are sources that have incredible potential to fulfil nutrition demand. The present aim of the investigation was to develop oyster mushroom cookies mushrooms from locally accessible crude materials. Raw mushrooms were cleaned in normal water, whitened with steam for 10 minutes, sliced for uniform size, and kept dry in a solar dryer at 35℃ for 8 hours. Prepared a composition of flour, Rava, sugar, mushroom powder, milk powder, ghee, baking powder, baking soda, and salt for making biscuits. Mix all the ingredients and make the dough, roll it with the help of a rolling pin and keep it in the microwave at 170℃ for 40 minutes. After this, It was cooled and kept at room temperature and kept it in an air-tight container. The Biscuits were ready and sliced in uniform size in the form of round and square shapes for packaging. After analysis, it was found that mushroom-fortified cookies have high protein content, low-fat content, high fibre, minerals and vitamin content which will be useful to overcome malnutrition problems.

Due to their excellent flavour and taste, Pleurotus species, which flourish in temperate and subtropical environments, are well-liked among edible mushrooms. Oyster mushrooms could be grown on a variety of substrates due to their powerful enzymatic properties. Pleurotus sp. grows more easily, more profitably, and more nutrient-densely on a variety of organic waste raw materials and environmental factors. Sterilization of the substrate is one of the most crucial steps in oyster mushroom cultivation. There have been numerous reports of contaminated mushroom substrate. Suitable sterilization techniques must be used on the substrates. There are several treatments for mushroom substrate that can be used to manage the frequent moulds that infest edible mushrooms. Sterilization of the substrate is necessary to get rid of pathogenic and rival microorganisms and to encourage the mycelial growth of the desired mushroom species. The goal of the current study was to identify the best treatment strategy for the chosen substrates. For substrate treatment for Pleurotus florida cultivation, hot water, boiling water, steam sterilization in an autoclave, and chemical treatment methods were used. It was observed that the steam sterilization method was superior to other methods as it supported relatively short spawn run duration, amazing yield, and high biological efficiency.

Agricultural wastes and leaves, which are classified as lignocellulosic biomass, have been used as substrates in the production of fungal foams due to the significant growth of the mushroom industry in recent years. Foam derived from fungi can be utilized in a variety of industrial applications, including the production of packaging materials. Here, white oyster mushrooms (Pleurotus florida) and yellow oyster mushrooms (Pleurotus citrinopileatus) were cultivated on rice husk, sawdust, sugarcane bagasse, and teak leaves. Fungal foams were produced after 30 days of incubation, which were then analyzed using scanning electron microscopy (SEM), thermal analysis (TGA), and chemical structure using Fourier-transform infrared spectroscopy. Mechanical testing examined the material’s hardness, resilience, and springiness, and water absorption tests were used to determine the durability of the fungal foams. Our findings demonstrated that fungal foams made from rice husk and teak leaves in both mycelium species showed better mechanical properties, thermal stability, and minimal water absorption compared to the other substrates, and can thus have great potential as efficient packaging materials.

The oyster mushroom (Pleurotus ostreatus) is an edible mushroom that belongs to the class of Basidiomycetes. It has reached sufficient market maturity because of its flavor, shelf-life durability, and protein and fiber content. Besides their nutritional, medicinal, and economic value, they may help the country’s agricultural waste management, bridge environmental issues, and contribute to climate change resolution advancements. A study on different varieties of agricultural substrates derived from waste materials such as cassava peels, coconut residue, and coffee waste was investigated and compared to sawdust, the common substrate for oyster mushrooms. The effects of different substrates on the morphological characteristics of P. ostreatus, percent contamination, and yield parameters were recorded and analyzed using the Analysis of Variance in Completely Randomized Design, and their significant results were compared using Tukey’s HSD. Results showed that different substrate mixtures did not significantly influence the morphological characteristics of P. ostreatus. Moreover, sawdust, the common substrate for oyster mushrooms, showed the lowest percent contamination as compared to other substrate mixtures. Contaminants found in cassava substrates include Trichoderma spp., Aspergillus spp., Fusarium spp., Neurospora spp., and Penicillium spp. 80% of cassava peels combined with 10% coconut residue and 10% coffee waste significantly increased the number of fruiting bodies and produced the heaviest fresh weights of oyster mushrooms. Stipe length and pileus diameter were also significantly influenced by this substrate mixture, which is comparable to the common substrate. However, further research on the varying proportions of these substrate mixtures on the performance of oyster mushrooms is recommended.

The abundance of coconut waste in North Sulawesi has not been processed and used optimally, then it becomes waste for the environment. Coconut coir processing for planting medium is limited only for coconut peat (coconut husk powder). One drawback in processing coconut peat requires special equipment and the fuel is expensive. This study aimed to compare the use coconut peat and coconut coir as growing medium for white oyster mushroom. Coconut coir was cut 3cm x 2cm x 1cm in size, while the comparison medium uses a coconut peat. Compositions of both media are coconut coir / coconut peat 83%, 16% ricebran, 1% limestone, 60% water. The result showed that coconut coir more productive than coconut peat. Coconut coir media produces 120.62 grams while the coconut peat media weighing 116.11 grams on each harvesting. Based on the result it can be conclude the usage of coconut coir was better compare than coconut peat for cultivation of oyster mushroom. Key words: Coconut waste, coconut coir, coconut peat, media, mushroom

Abstract Eleven fungal isolates were isolated from oyster mushroom culture media. 10 isolates showed antagonistic activity against P. pulmonarius, while two fungal isolates did not show any antagonistic activity. the highest pathogenic fungi were identified as T. longibrachiatum, T. pleuroticola, R. arrhizus, M. hiemalis and P. glabrum according to the morphological and molecular methods and were registered in the World Genetic Bank at NCBI with the accession numbers OM438162.1, OM438163.1, OM438161.1, OM453951.1 and OM438160.1, respectively, the species T. pleuroticola, R. arrhizus and M. hiemalis were recorded for the first time in Iraq at the molecular level. The effect of some oils on the growth of the oyster mushroom P. pulmonarius and its pathogenic fungi was studied, the results showed that the highest effect of jojoba oil, olive oil, almond oil, sesame oil and coconut oil at 5% was recorded the highest inhibition of the all tested pathogenic fungi, while no inhibitory effect was recorded for the oyster mushroom P. pulmonarius. Sodium bicarbonate at 3 and 5% showed complete inhibition of the growth of all pathogenic fungi. The results showed that 5% of acetic acid inhibits the pathogenic fungi T. longibrachiatum, R. arrhizus and T. pleuroticola, where the diameters of the colonies reached 2.5, 2.7 and 3.1 cm. respectively. The highest biological efficiency was recorded in P. eryngii growing in the medium treated with the pathogenic fungus P. glabrum in presence of sodium bicarbonate, which reached to 69.58%. In the interaction between oyster mushroom species and the media, the results showed that the highest infection rate was in P. eryngii in the medium treated with T. longibrachiatum, which reached to 39.56%, while the lowest infection rate was with P. pulmonarius grown in the medium treated with sodium bicarbonate and the pathogenic fungus P. glabrum, which was 13.15%. Under the pathogens infection, the highest protein content was found in P. eryngii grown in the treated medium with sodium bicarbonate and P. glabrum resulting in 31.22%, while the lowest protein was12.07%. in P. ostreatus grown in the medium infected with T. longibrachiatum.
