Abstract

The taxonomic position of a Gram-stain-positive, endospore-forming bacterium, strain KS16-9, isolated from a marine sediment sample collected from Kovalam, Kanyakumari coastal region of the Indian Ocean, India, was analysed by a polyphasic approach. Strain KS16-9 had typical phenotypic characteristics and chemotaxonomic features (menaquinones, fatty acids and lipids) that were consistent with the genus . omparative analysis of the 16S rRNA gene sequence of the strain with previously published type strains confirmed that it belongs to the genus and is moderately related to B48 (98.42 % similarity), followed by CV53 (97.67 %) and (97.61 %). Other species in the genus shared <97.6 % 16S rRNA gene sequence similarity. Strain KS16-9 contained MK-7 as the predominant menaquinone, -diaminopimelic acid as the diagnostic cell-wall diamino acid, iso-C and anteiso-C as major fatty acids, and diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine as the major phospholipids. The DNA G+C content of strain KS16-9 was 45.4 mol%. Based on data from this polyphasic taxonomic study, strain KS16-9 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is KS16-9 (=MTCC 12305=DSM 100413=KCTC 33834).
