Microbial communities play important roles in the biogeochemical cycling of carbon in the Earth's deep subsurface. Previously, we demonstrated changes to the microbial community structure of a deep aquifer (1.4 km) receiving 150 tons of injected supercritical CO2 (scCO2 ) in a geosequestration experiment. The observed changes support a key role in the aquifer microbiome for the thermophilic CO-utilizing anaerobe Carboxydocella, which decreased in relative abundance post-scCO2 injection. Here, we present results from more detailed metagenomic profiling of this experiment, with genome resolution of the native carboxydotrophic Carboxydocella. We demonstrate a switch in CO-oxidation potential by..View full abstract
