The chemosynthetic biofilm microbiome of deep-sea hydrothermal vents across space and time.

ABSTRACT: Microbial biofilms colonize mineral and biological substrates exposed to fluid circulation at deep-sea hydrothermal vents, providing a biologically active interface along redox boundaries. Since many biofilms at deep-sea vents are associated with invertebrates, microbial distribution and abundance are not only constrained by local fluid geochemistry, but also through host-microbe interactions. This study examined the spatial distribution and diversity of established microbial biofilm communities collected from three distinct biological regimes characteristic of the East Pacific Rise (9°50 N, 104°17 W) vent system, as well as newly established biofilms on experimental microbial colonization devices. Transcripts from 16S rRNA-based amplicon sequencing revealed that Campylobacterota of the Su
