The deoxyribonucleic acid (DNA) relationships among strains of the thermophilic species Clostridium thermohydrosulfuricum, C. thermosaccharolyticum, and C. tartarivorum, other saccharolytic, proteolytic, and acetate-producing clostridia, and some sulfate-reducing bacteria were studied by DNA-DNA hybridization experiments. Strains of the species C. thermohydrosulfuricum were found to constitute a genotypically homogeneous group clearly unrelated to the strains of the species C. thermosaccharolyticum and other competitor strains used. Strains of the species C. tartarivorum showed a high level of homology with the reference strain C. thermosaccharolyticum ATCC 7956. The guanine-plus-cytosine contents of the acetate-forming clostridia C. formicoaceticum and C. thermoaceticum were 34.0 and 54.0 mol%, respectively.
