Streszczenie:

In the past decades, the taxonomic status of the cyanobacterial family Phormidiaceae has always been chaotic and problematic. In this study, filamentous cyanobacteria were investigated in the east of China, and twenty strains isolated from different locations of Zhejiang Province were characterized. Using the polyphasic approach combining morphological, molecular and phylogenetic features, these strains were grouped within the members of the genera Ancylothrix and Potamolinea, the newly recorded genera of cyanobacteria in China. Based on the collected taxonomic information of the family Phormidiaceae, cyanobacterial systematics at family level were further discussed. This study provided a simple and efficient example to perform the phylogenetic evaluation for the monophyly and rationality of currently used families of cyanobacteria by using the regional strains based on the polyphasic approach.

Streszczenie:

Trichoderma speies are known for their diverse applications as potent bio-control organisms. 34 isolates of Trichoderma were obtained from various geographical locations in India and were subjected to phenotypic evaluation. Species identification if based on only morphology, may lead to sometimes erroneous, uncertain or remains unclear due to overlapping characters. Therefore, molecular characterization was also performed based on ITS region sequence analysis for reliable identification using both morphological and molecular characters. The isolates were identified into 20 different species viz., T. aggressivum, T. asperellum, T. atroviride, T. brevicompactum, T. citrinoviride, T. crassum, T. erinaceum, T. ghanense, T. hamatum, T. harzianum, T. koningiopsis, T. longibrachiatum, T. longipile (Syn. Hypocrea longipilosa), T. minutisporum, T. pubscenes, T.reesei, T. saturnisporum, T. spirale, T. tomentosum and T. virens based on the integrated approach of both morphological and molecular characterisation. ß-tub gene sequence analysis was also performed to find out the phylogenetic relationship of these species. The ß-tub gene sequences differentiated all the 20 different species of Trichoderma better than the ITS region sequences. The morphological characters viz., colony, conidiophores, phialides, conidia and chlamydospores of all the twenty species of Trichoderma were described along with photomicrographs. The ITS and β-tub gene sequences of all the 20 species studied have been deposited in the Genbank.

Streszczenie:

One hundred and seventy-eight lactobacilli isolated from wine were characterized by a polyphasic approach. Strains were phenotypically identified at genus and species level by classical tests including the analysis of cell morphology, homo/heterofermentative character, sugar fermentation patterns, growth at different temperatures and the optical nature of the isomer of lactic acid produced from glucose. Molecular techniques such as random amplification of polymorphic DNA (RAPD), amplified 16S rDNA restriction analysis (16S-ARDRA), PFGE-RFLP and ribotyping were used to characterize strains, and their potential for identification and/or typing was evaluated. The information obtained with these techniques was processed with the BioNumerics software in order to analyse relationships existing between isolated strains and various reference species of the genus. Then, taxonomic dendrograms were obtained, and this information allowed the proposal of molecular procedures suitable for the identification and typing of these wine micro-organisms. The techniques useful for both identification and typing were RAPD and ribotyping, while 16S-ARDRA was only useful for identification and PFGE-RFLP only for typing purposes. The wine strains were identified as Lactobacillus brevis (19 strains), Lactobacillus collinoides (2 strains), Lactobacillus hilgardii (71 strains), Lactobacillus paracasei (13 strains), Lactobacillus pentosus (2 strains), Lactobacillus plantarum (34 strains) and Lactobacillus mali (10 strains).

Streszczenie:

Molecular systematic methods were applied in a series of studies designed to resolve the taxonomic relationships of thermophilic actinomycetes known to be difficult to classify using standard taxonomic procedures. The test strains included representatives of clusters defined in an extensiven umerical phenetic survey of thermophilic streptomycetesa nd twelve marker strains. The resultant genotypic data together with the results of corresponding phenotypic studies were used to highlight novel taxa and to improve the circumscription of validly described species. The most comprehensive study was undertaken to clarify relationships within and between representative alkalitolerant, thermophilic and neutrophilic, thermophilic streptomycetes isolated from soil and appropriate marker strains. The resultant data, notably those from DNA: DNA relatedness studies, supported the taxonomic integrity of the validly described species Streptomyces thermodiastaticus, Streptomyces thermoviolaceus and Streptomyces thermovulgaris. However, the genotypic and phenotypic data clearly show that Streptomyces thermonitrificans Desai and Dhala 1967 and Streptomyces thermovulgaris (Henssen 1957) Goodfellow et al. 1987 represent a single species. On the basis of the priority, Streptomyces thermonitrificans is a later subjective synonym of Streptomyces thermovulgaris. Similarly, eight out of eleven representative alkalitolerant, thermophilic isolates and three out of sixteen representative neutrophilic, thermophilic isolates had a combination of properties consistent with their classification as Streptomyces thermovulgaris. One of the remaining alkalitolerant, thermophilic isolate, Streptomyces strain TA56, merited species status. The name Streptomyces thermoalcalitolerans sp. nov. is proposed for this strain. A neutrophilic, thermophilic isolate, Streptomyces strain NAR85, was identified as Streptomyces thermodiastaticus. Four other neutrophilic thermophilic isolates assigned to a numerical phenetic cluster and a thermophilic isolates from poultry faeces were also considered to warrant species status; the names Streptomyces eurythermophilus sp. nov. and Streptomyces thermocoprophilus sp. nov. are proposed to accommodate these strains. It was also concluded that additional comparative taxonomic studies are required to clarify the relationships between additional thermophilic streptomycete strains included in the present investigation. A corresponding polyphasic approach was used to clarify the taxonomy of six thermophilic isolates provisionally assigned to either the genera Amycolatopsis or Excellospora. Two of the isolates, strain NT202 and NT303, had properties consistent with their classification in the genus Amycolatopsis. However, the genotypic and phenotypic data also showed that these strains formed a new centre of taxonomic variation for which the name Amycolatopsis eurythermus sp. nov. is proposed. Similarly, the four remaining strains formed two new centre of taxonomic variation within the genus Excellospora. It is proposed that isolates TA113 and TA114 be designated Excellospora alcalithermophilus sp. nov. Similarly, the name Excellospora thermoalcalitolerans sp. nov. is proposed for strains TA86 and TA111. An emended description is also given for the genus Excellospora.

Streszczenie:

Abstract This book chapter is organized as follows: (i) the main approaches to the philosophy of taxonomic classification are recapitulated; (ii) the paradigm of polyphasic taxonomy is discussed in this context; (iii) the causes of conflict between previous classifications and genome-scale analyses are investigated, using examples from recent phylum-wide studies, with a discussion of how markers used in polyphasic taxonomy can be replaced by genome-derived ones; and (iv) the challenges in assigning taxonomic ranks using genome-scale or other data are revisited. The conclusion assesses the chances, or lack thereof, of reconciling taxonomic classifications. Phenetic and phylogenetic thinking still compete with each other on the classification of bacteria, with potentially conflicting and confusing results. Some causes of problematic taxonomic classifications are independent of the type and number of characters that can be used and can only be mitigated if, for example, taxon sampling and branch support are more appropriately taken into account. It may be possible to devise objective criteria for separating bacterial species, but the currently dominating approaches for microbial species delineation may be inadequate. It is even harder to delineate higher taxa; in contrast to claims in the literature, it may prove to be impossible to objectively assign taxonomic ranks above species level.

Polypharmic patients are patients who chronically use five or more medicines. The number of polypharmacy patients continues to increase even though it is a risk factor for morbidity and mortality. A medication review is an important measure to mitigate medication risks. It is known to effectively reduce the number of drug related problems per (polypharmic) patient. STRIP is a Dutch method to perform a structured medication review. Based on this method, the STRIPA(ssistent) tool is developed. However, whether or not this app is considered useful by the healthcare professional is not known yet. In order to assess this, a systematic literature study is conducted. In addition, an effectiveness study design is described. The results show that there is indeed a need for medication reviews and Dutch healthcare professionals are likely to adopt new technologies, an effectiveness study based on a randomized controlled trial is necessary to assess the effectiveness of STRIPA.

Streszczenie:

Brazil has 10.959 km of coastline which includes three ecoregions based on the biogeographic system, exhibiting a wide range of environments that favor the occurrence of numerous cyanobacterial morpho- and ecotypes. These organisms have a great adaptive capacity, which explains their occupancy in numerous environments and the high diversification of the group. Historically, the cyanobacteria have been classified only based on morphology, which makes their taxonomy quite challenging. There is usually little morphological variation between taxa, which makes it difficult to identify diacritical characteristics between some genera and species, making intergeneric and intraspecific delimitation tough. Thereby, the polyphasic approach based on different tools allows the identification of new taxa and the reassessment of those already established with more reliability, contributing to a better systematic resolution of the world ‘cyanoflora’, a term that we propose herein to describe the diversity of Cyanobacteria into Phycoflora area. However, the use of these tools is still not widely applied to most genera and species, especially those from tropical and subtropical environments, which has limited the real recognition of their biodiversity, as well as the knowledge about the cyanobacteria’s evolutionary history and biogeography. In Brazil, even with the great development of phycological studies, the knowledge about Cyanobacteria from marine benthic environments has not evolved to the same degree. This phylum has been neglected in floristic surveys, presenting only 46 benthic species reported to the long Brazilian coastline, evidencing the still incipient knowledge about the diversity and distribution of this microorganism’s group. Furthermore, biotechnological properties of Brazilian marine cyanobacteria are still almost completely unknown, with only three studies carried out to date, underestimating one of the most diverse groups and with promising potential for the possibility of isolating new biochemically active compounds. The ten new taxa related to the Brazilian coast in the last decade emphasizes the challenge of conducting further floristic surveys in the underexplored marine environments in order to fill an important lacune in the cyanoflora knowledge, as well as their biogeographic distribution and biotechnological potential. Besides, the recognition of the Brazilian cyanoflora makes an important contribution to the understanding of the functioning and monitoring of marine ecosystems and provide data for the construction of future public policies, which is a goal of the United Nations Decade for Ocean Science for Sustainable Development.

Streszczenie:

The Mooshla Intrusive Complex (MIC) is an Archean polyphase magmatic body located in the Doyon-Bousquet-LaRonde (DBL) mining camp of the Abitibi greenstone belt, Québec, that is spatially associated with numerous gold (Au)-rich VMS, epizonal 'intrusion-related' Au-Cu vein systems, and shear zone-hosted (orogenic?) Au deposits. To elucidate the P-T conditions of crystallization, and oxidation state of the MIC magmas, accessory minerals (zircon, rutile, titanite) have been characterized using a variety of analytical techniques (e.g., trace element thermobarometry). The resulting trace element and oxythermobarometric database for accessory minerals in the MIC represents the first examination of such parameters in an Archean magmatic complex in a world-class mineralized district. Mineral thermobarometry yields P-T constraints on accessory mineral crystallization consistent with the expected conditions of tonalite-trondhjemite-granite (TTG) magma genesis, well above peak metamorphic conditions in the DBL camp. Together with textural observations, and mineral trace element data, the P-T estimates reassert that the studied minerals are of magmatic origin and not a product of metamorphism. Oxygen fugacity constraints indicate that while the magmas are relatively oxidizing (as indicated by the presence of magmatic epidote, titanite, and anhydrite), zircon trace element systematics indicate that the magmas were not as oxidized as arc magmas in younger (post-Archean) porphyry environments. The data presented provides first constraints on the depth and other conditions of melt generation and crystallization of the MIC. The P-T estimates and qualitative fO2 constraints have significant implications for the overall model for formation (crystallization, emplacement) of the MIC and potentially related mineral deposits.

Streszczenie:

The Mooshla Intrusive Complex (MIC) is an Archean polyphase magmatic body located in the Doyon-Bousquet-LaRonde (DBL) mining camp of the Abitibi greenstone belt, Québec. The MIC is spatially associated with numerous gold (Au)-rich VMS, epizonal 'intrusion-related' Au-Cu vein systems, and shear zone-hosted (orogenic?) Au deposits. To elucidate genetic links between deposits and the MIC, mineralized samples from two of the epizonal 'intrusion-related' Au-Cu vein systems (Doyon and Grand Duc Au-Cu) have been characterized using a variety of analytical techniques. Preliminary results indicate gold (as electrum) from both deposits occurs relatively late in the systems as it is primarily observed along fractures in pyrite and gangue minerals. At Grand Duc gold appears to have formed syn- to post-crystallization relative to base metal sulphides (e.g. chalcopyrite, sphalerite, pyrrhotite), whereas base metal sulphides at Doyon are relatively rare. The accessory ore mineral assemblage at Doyon is relatively simple compared to Grand Duc, consisting of petzite (Ag3AuTe2), calaverite (AuTe2), and hessite (Ag2Te), while accessory ore minerals at Grand Duc are comprised of tellurobismuthite (Bi2Te3), volynskite (AgBiTe2), native Te, tsumoite (BiTe) or tetradymite (Bi2Te2S), altaite (PbTe), petzite, calaverite, and hessite. Pyrite trace element distribution maps from representative pyrite grains from Doyon and Grand Duc were collected and confirm petrographic observations that Au occurs relatively late. Pyrite from Doyon appears to have been initially trace-element poor, then became enriched in As, followed by the ore metal stage consisting of Au-Ag-Te-Bi-Pb-Cu enrichment and lastly a Co-Ni-Se(?) stage enrichment. Grand Duc pyrite is more complex with initial enrichments in Co-Se-As (Stage 1) followed by an increase in As-Co(?) concentrations (Stage 2). The ore metal stage (Stage 3) is indicated by another increase in As coupled with Au-Ag-Bi-Te-Sb-Pb-Ni-Cu-Zn-Sn-Cd-In enrichment. The final stage of pyrite growth (Stage 4) is represented by the same element assemblage as Stage 3 but at lower concentrations. Preliminary sulphur isotope data from Grand Duc indicates pyrite, pyrrhotite, and chalcopyrite all have similar delta-34S values (~1.5 � 1 permille) with no core-to-rim variations. Pyrite from Doyon has slightly higher delta-34S values (~2.5 � 1 permille) compared to Grand Duc but similarly does not show much core-to-rim variation. At Grand Duc, the occurrence of Au concentrating along the rim of pyrite grains and associated with an enrichment in As and other metals (Sb-Ag-Bi-Te) shares similarities with porphyry and epithermal deposits, and the overall metal association of Au with Te and Bi is a hallmark of other intrusion-related gold systems. The occurrence of the ore metal-rich rims on pyrite from Grand Duc could be related to fluid boiling which results in the destabilization of gold-bearing aqueous complexes. Pyrite from Doyon does not show this inferred boiling texture but shares characteristics of dissolution-reprecipitation processes, where metals in the pyrite lattice are dissolved and then reconcentrated into discrete mineral phases that commonly precipitate in voids and fractures created during pyrite dissolution.
