Gammaproteobacteria mediating utilization of methyl-, sulfur- and petroleum organic compounds in deep ocean hydrothermal plumes.

ABSTRACT: Deep-sea hydrothermal plumes are considered natural laboratories for understanding ecological and biogeochemical interactions. Previous studies focused on interactions between microorganisms and inorganic, reduced hydrothermal inputs including sulfur, hydrogen, iron, and manganese. However, little is known about transformations of organic compounds, especially methylated, sulfur-containing compounds, and petroleum hydrocarbons. Here, we reconstructed nine gammaproteobacterial metagenome-assembled genomes, affiliated with Methylococcales, Methylophaga, and Cycloclasticus, from three hydrothermal ecosystems. We present evidence that these three groups have high transcriptional activities of genes encoding cycling of C₁-compounds, petroleum hydrocarbons, and organic sulfur in hydro
