Growth of microorganisms in environments containing CO2 above its critical point is unexpected due to a combination of deleterious effects, including cytoplasmic acidification and membrane destabilization. Thus, supercritical CO2 (scCO2) is generally regarded as a sterilizing agent. We report isolation of bacteria from three sites targeted for geologic(More)
Supercritical (sc) CO 2 usage is increasing globally with applications as a sterilizing agent, as a non-toxic solvent, and as the form of the greenhouse gas CO 2 injected underground for geologic carbon sequestration (GCS). In this thesis I have described the isolation of microorganisms from three different carbon sequestration pilot sites through a novel(More)
We report draft genome sequences of Bacillus subterraneus MITOT1 and Bacillus cereus MIT0214 isolated through enrichment of samples from geologic sequestration sites in pressurized bioreactors containing a supercritical (sc) CO2 headspace. Their genome sequences expand the phylogenetic range of sequenced bacilli and allow characterization of molecular(More)
