Genomic Description of 'Candidatus Abyssubacteria,' a Novel Subsurface Lineage Within the Candidate Phylum Hydrogenedentes.

ABSTRACT: The subsurface biosphere is a massive repository of fixed carbon, harboring approximately 90% of Earth's microbial biomass. These microbial communities drive transformations central to Earth's biogeochemical cycles. However, there is still much we do not understand about how complex subterranean microbial communities survive and how they interact with these cycles. Recent metagenomic investigation of deeply circulating terrestrial subsurface fluids revealed the presence of several novel lineages of bacteria. In one particular example, phylogenomic analyses do not converge on any one previously identified taxon; here we describe the first full genomic sequences of a new bacterial lineage within the candidate phylum Hydrogenedentes, 'Candidatus Abyssubacteria.'
