Subsurface carbon monoxide oxidation potentials revealed through genome-resolved metagenomics of a carboxydotroph

Microbes play a key role in the biogeochemical cycling of carbon in the Earth's deep subsurface. This study is associated with a field-scale demonstration of supercritical CO2 geosequestration. Observed changes to the subsurface microbial community supports an important role in the aquifer microbiome for the thermophilic CO-utilizing anaerobe, Carboxydocella. Here, we employed genome-resolved metagenomics to reconstruct an aquifer-native Carboxydocella genome to near-complete.
