Abstract

The taxonomic position of a Gram-stain positive bacterium isolated from a solar saltern sample collected from Kanyakumari, coastal region of the Bay of Bengal, India, was analysed by using a polyphasic approach. The isolated strain, designated SA2-6, had phenotypic characteristics that matched those of the genus . The 16S rRNA gene sequence (1493 bases) of the novel strain was compared with those of previously studied type strains and confirmed that the strain belongs to the genus and was moderately closely related to the type strain of at 97.5 % 16S rRNA gene sequence similarity, followed by those of (96.9 %), (96.8 %), (96.6 %), (96.6 %) and (96.6 %). 16S rRNA gene sequence analysis indicated that strain SA2-6 differs from all other species of the genus by at least 2.5 %. It contained MK-7 as the predominant menaquinone, -diaminopimelic acid as the diagnostic cell-wall diamino acid, and iso-C and anteiso-C as major fatty acids. Major lipids were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG) and phosphatidylethanolamine (PE). Based on data from this polyphasic study, strain SA2-6 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SA2-6 ( = MTCC 11848 = DSM 28801). The draft genome of strain SA2-6 consisted of 5 183 363 bp with G+C content of 45.44 mol%, 5352 predicted coding sequences, 191 RNAs and 479 subsystems.
