| Abstract: | Both natural and anthropogenic hot environments contain appreciable levels of carbon monoxide (CO). Anaerobic microbial communities play an important role in CO conversion in such environments. CO is involved in a number of redox reactions. It is biotransformed by thermophilic methanogens, acetogens, hydrogenogens, sulfate reducers, and ferric iron reducers. Most thermophilic CO-oxidizing anaerobes have diverse metabolic capacities, but two hydrogenogenic species are obligate carboxydotrophs. Among known thermophilic carboxydotrophic anaerobes, hydrogenogens are most numerous, and based on available data they are most important in CO biotransformation in hot environments. |
