| Abstract: | Strains J5B(T) and M52(T) are facultatively autotrophic sulfur-oxidizing bacteria isolated from a microbial mat from a hot spring. They were isolated and partially characterized in previous studies, as facultative anaerobes which use nitrate as electron acceptor. In this study, additional characterizations were made to determine their taxonomic status. In both strains, major cellular fatty acids were C-16:1 (C-16:1 omega 7c and/or C-16:1 omega 6c) and C-16:0. Their chemolithoautotrophic growth was supported by thiosulfate and elemental sulfur. They used some organic acids as growth substrates. Their 16S rRNA gene sequences indicated the highest sequence identities to species in the family Sterolibacteriaceae, but the identities were 95% or lower. Phylogenetic analysis indicated that these strains do not belong to any existing genera. Values of average nucleotide identity and digital DNA-DNA hybridization between strains J5B(T) and M52(T) were 87.93% and 34.3%, respectively. On the basis of phenotypic and genomic characteristics, Sulfuricystis multivorans gen. nov. sp. nov., and Sulfuricystis thermophila sp. nov. are proposed, with type strains of J5B(T) and M52(T), respectively. An emended description of the genus Rugosibacter is also proposed, for its reclassification to the family Sterolibacteriaceae. |
