Prokaryotic Life Associated with Coal-Fire Gas Vents Revealed by Metagenomics.

ABSTRACT: The natural combustion of underground coal seams leads to the formation of gas, which contains molecular hydrogen and carbon monoxide. In places where hot coal gases are released to the surface, specific thermal ecosystems are formed. Here, 16S rRNA gene profiling and shotgun metagenome sequencing were employed to characterize the taxonomic diversity and genetic potential of prokaryotic communities of the near-surface ground layer near hot gas vents in an open quarry heated by a subsurface coal fire. The communities were dominated by only a few groups of spore-forming Firmicutes, namely the aerobic heterotroph Candidatus Carbobacillus altaicus, the aerobic chemolitoautotrophs Kyrpidia tusciae and Hydrogenibacillus schlegelii, and the anaerobic chemolithoautotrop
