A novel bacterial phylum that participates in carbon and osmolyte cycling in the Challenger Deep sediments

Cui et al. (2021). Environmental Microbiology 23 (7)
SummaryLarge amounts of detrital organic matter and osmolytes accumulate in the sediments of hadal trenches (>6000 m depth) due to the funnelling effect. It is still unknown whether there are novel active microbes that depend on specific carbon sources in extreme and isolated environments. In this study, we present a novel active bacterial phylum, Candidatus Tianyabacteria in the FCB superphylum, which was enriched in sediments collected from the Challenger Deep. Genome binning resulted in hi
