Genomic insights into potential interdependencies in microbial hydrocarbon and nutrient cycling in hydrothermal sediments.

ABSTRACT:

Background

Deep-sea hydrothermal vents are hotspots for productivity and biodiversity. Thermal pyrolysis and circulation produce fluids rich in hydrocarbons and reduced compounds that stimulate microbial activity in surrounding sediments. Several studies have characterized the diversity of Guaymas Basin (Gulf of California) sediment-inhabiting microorganisms; however, many of the identified taxa lack cultures or genomic representations. Here, we resolved the metabolic potential and community-level interactions of these diverse communities by reconstructing and analyzing microbial genomes from metagenomic sequencing data.

Results

We reconstructed 115 microbial metagenome-assembled genomes comprising 27 distinct archaeal and bacterial phyla. The archaea included members of the
