N2 - A novel type of a sulfate-reducing microorganism, represented by strain Na82T, was isolated from a hot spring in Narugo, Japan. The isolate was a moderate thermophilic autotroph that was able to grow on H 2/CO2 by sulfate respiration. The isolate could grow with nitrate in place of sulfate, and possessed menaquinone-7 and menaquinone-7(H2) as respiratory quinones. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain Na82T was a member of the domain Bacteria and distant from any known bacteria, as well as from other sulfate-reducing bacteria (sequence similarities less than 80%). The phylogenetic analysis of the dsrAB gene (alpha and beta subunits of dissimilatory sulfite reductase) sequence also suggested that strain Na82 T was not closely related to other sulfate reducers. On the basis of the phenotypic and phylogenetic data, a new taxon is established for the isolate. We proposed the name Thermodesulfobium narugense gen. nov., sp. nov. with strain Na82T (=DSM 14796T=JCM 11510T) as the type strain. Furthermore, a new family, Thermodesulfobiaceae fam. nov., is proposed for the genus.
