| Popis: | Cells of members of the family Clostridiaceae , phylum Firmicutes , are generally obligate anaerobic rods. Strains D2Q-14T and D2Q-11T were isolated from sediment of the saline lake Manisi in the Xinjiang Uygur Autonomous Region, PR China. In this study, we employed a polyphasic approach and whole genome analysis of the two isolates. Cells of both isolates were Gram-stain-positive rods that were motile by means of flagella and could utilize sulphate, thiosulphate, elemental sulphur and nitrate as electron acceptors. Phylogenetic analyses based on 16S rRNA gene and whole genome sequences indicated that strains D2Q-14T and D2Q-11T constituted a coherent cluster affiliated to the family Clostridiaceae . In addition, genome analysis revealed that strain D2Q-14Tharboured one nonribosomal peptide synthetase gene cluster, making up 1.4 % of the entire genome. The genome-based analysis, including average nucleotide identity, average amino acid identity and in silico DNA–DNA hybridization, biochemical, phenotypic and chemotaxonomic characterization, indicated that strains D2Q-14T and D2Q-11T represented two novel species of a novel genus in the family Clostridiaceae , for which we propose the names Anaeromonas gelatinilytica gen. nov., sp. nov. and Anaeromonas frigoriresistens sp. nov., with the type strains D2Q-14T (=KCTC 15986T=MCCC 1K04634T) and D2Q-11T (=KCTC 15985T=MCCC 1K04391T), respectively. |
