| Research Abstract |
To construct a platform towards next-generation technology for recycling of carbon dioxide (CO2), we explored novel hyperthermophilic microorganisms possessing carbon monoxide dehydrogenases (CODHs) that can catalyze both CO oxidation and CO2 reduction (carboxydotrophic bacteria). We isolated a novel carboxydotrophic hydrogenogenic bacterium strain KKC1 from a marine sediment core sample. This bacterium grew chemolithotrophically producing H2 from CO oxidation with reduction of oxidized iron or sulfides. We also showed that carboxydotrophic bacteria may be dominate in hot environments.
