Subsurface Carboxydocella CO-Oxidation Aquifer Community

Community ID CommunityMech:000251
Ecological State PERTURBED
Environment deep aquifer geosequestration test bed
ENVO:01001004

A deep subsurface (1.4 km) aquifer microbial community perturbed by injection of 150 tons of supercritical CO2 (scCO2) in a geosequestration experiment. Detailed genome-resolved metagenomics resolved the native carboxydotrophic Carboxydocella, a thermophilic CO-utilizing anaerobe whose relative abundance decreased post-scCO2 injection. Analysis of its carbon monoxide dehydrogenase (CODH) gene before and after the experiment documented a switch in CO-oxidation potential by Carboxydocella, with implications for subsurface flow of carbon and electrons from oxidation of the metabolic intermediate CO.
