Abstract

A Gram-staining-positive, cocci, halotolerant bacterial strain, designated as SV-16T, was isolated from marine sediment and subjected to a polyphasic taxonomic study. The strain exhibited phenotypic properties that included chemotaxonomic characteristics consistent with its classification in the genus Salinicoccus. Growth occurs at temperatures in the range between 25-37 °C (optimum 30 °C), pH 7.0-11.0 (optimum 8.0) and at NaCl concentrations up to 25 .0 % (optimum 15.0 %). The highest level of 16S rRNA gene sequence similarity was with Salinicoccus carnicancri CrmT (98.6  %) followed by Salinicoccus halodurans W24T (96.6 %). The predominant polar lipids are diphosphatidylglycerol (DPG), phosphatidylinositol (PI) and phosphatidylglycerol (PG). The major cellular fatty acids are iso-C15: 0, anteiso-C15: 0, iso-C17: 0 and anteiso C17: 0. The draft genome of strain SV-16T consisted of 2,591,284 bp with G+C content of 48.7 mol %. On the basis of the phenotypic characteristics and genotypic distinctiveness of strain SV-16T, it should be classified within a novel species of Salinicoccus, for which the name Salinicoccus sediminis sp. nov. is proposed. The type strain is SV-16T (=MTCC 11832T= DSM 28797T).
