- Аннотация: Candidate bacterial phylum BRC1 has been identified in a broad range of mostly organic-rich oxic and anoxic environments through molecular analysis of microbial communities. None of the members of BRC1 have been cultivated and only a few draft genome sequences have been obtained from metagenomes or as a result of single-cell sequencing. We have reconstructed complete genome of BRC1 bacterium, BY40, from metagenome of the microbial community of a deep subsurface thermal aquifer in the Tomsk Region of the Western Siberia, Russia, and used it for metabolic reconstruction and comparison with existing genomic data. Analysis of 3.3Mb genome of BY40 bacterium revealed numerous glycoside hydrolases that could enable utilization of carbohydrates, including enzymes of chitin-degradation pathway. The bacterium lacks flagellar machinery but the twitching motility is encoded. The reconstructed central metabolism revealed pathways enabling the fermentation of organic substrates, as well as their complete oxidation through aerobic and anaerobic respiration. Phylogenetic analysis using BY40 genome supported the phylum level classification of BRC1 lineage. Based on phylogenetic and genomic analyses, the novel bacterium is proposed to be classified as Candidatus Sumerlaea chitinivorans, within a candidate phylum Sumerlaeota.
