FIG 1.

Dominant SUP05 bacteria within the sponge-associated microbial community. (A) Relative abundances of operational taxonomic units corresponding to sponge-associated microorganisms at the genus level. Composition percentage is shown on the vertical axis. SUP05 bacteria were highly abundant in the microbial communities of both the Crane site vent sponge (CSVS) and the Swan site vent sponge (SSVS). (B) Genome binning of dominant SUP05 bacteria. SUP05 bacteria were sequenced with superhigh coverage (∼7,000×).
