Abstract—
High-performance sequencing of the 16S rRNA gene (V4 region) was used to reveal the most widespread groups of microorganisms in the bottom sediments of the Barents and Kara seas. In the Barents Sea, these were uncultured bacteria of the families Hyphomicrobiaceae, Anaerolineaceae, Desulfobulbaceae, and Desulfosarcinaceae (Sva0081 sediment group), actinobacteria of the genus Rhodococcus, and proteobacteria of the genus Woeseia. In the Kara Sea the most represented groups were uncultured bacteria of the order Sedimentisphaerales (the SG8-4 cluster, class Phycisphaerae, phylum Planсtomycetota), bacteria of the family Anaerolineaceae, the family Desulfosarcinaceae (the SEEP-SRB1 cluster), the deep phylogenetic cluster NB1-j, organotrophic proteobacteria of the genera Woeseia and Pseudomonas, and sulfate reducers of the genus Desulfatiglans. The patterns of microbial distribution were analyzed depending on the depth from the bottom surface and the presence of fluid discharge zones. It was found that according to analysis of the core microbiome, uncultured bacteria of the SG8-4 cluster and uncultured bacteria of the family Anaerolineaceae predominated in the methane discharge zones in the Barents and Kara seas.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
