The 16S rRNA gene of the thermophilic sulfate‐reducing bacterium Desulfotomaculum thermobenzoicum was amplified by polymerase chain reaction using two eubacterial consensus oligodeoxynucleotide primers flanking the majority of the 16S rRNA gene, cloned, and sequenced. Phylogenetic analysis revealed that D. thermobenzoicum belongs to the Gram‐positive (low G + C content) branch and is more related to the thermophilic sulfate‐reducing bacterium, D. australicum than the moderate thermophile D. nigrificans , or the mesophiles D. orientis , and D. ruminis . This relationship is further strengthened by the presence of an unusual idiosyncrasy in helix 6 of the 16S rRNA gene of D. thermobenzoicum resembling that of D. australicum but not found in other desulfotomacula species and in any other bacteria sequenced to date.
