Carboxydothermus hydrogenoformans is able to grow by conversion of CO to H2 and CO2. Besides CO, only pyruvate was described as serving as an energy source. Based on 16S rRNA gene sequence similarity, C. hydrogenoformans is closely related to Thermoterrabacterium ferrireducens. T. ferrireducens is like C. hydrogenoformans a gram-positive, thermophilic, strict anaerobic bacterium. However, it is capable of using various electron donors and acceptors for growth. Growth of C. hydrogenoformans with multiple electron donors and acceptors was tested. C. hydrogenoformans oxidized formate, lactate, glycerol, CO, and H2 with 9,10-anthraquinone-2,6-disulfonate as an electron acceptor. Sulfite, thiosulfate, sulfur, nitrate, and fumarate were reduced with lactate as an electron donor. T. ferrireducens oxidized CO with 9,10-anthraquinone-2,6-disulfonate as an electron acceptor but did not produce H2 from CO. In contrast to what was published before, T. ferrireducens was able to grow on lactate with sulfite, sulfur, and nitrate as electron acceptors.
