A Gram-negative, non-motile, rod-shaped bacterium, strain ISL-6T, phenotypically resembling members of the genus Salegentibacter, was isolated from a marine solar saltern of the Yellow Sea in Korea and subjected to a polyphasic taxonomic investigation. Strain ISL-6T grew optimally at pH 7.0-8.0 and 30 °C and in the presence of 8% (w/v) NaCl. It contained MK-6 as the predominant menaquinone. The major fatty acids were iso-C15:0 and anteiso-C15:0. The DNA G+C content was 37.5 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-6T belonged to the genus Salegentibacter. Strain ISL-6T exhibited 16S rRNA gene sequence similarity values of 92.0-98.6 % with respect to the type strains of recognized Salegentibacter species. Low DNA-DNA relatedness values, differential phenotypic properties and phylogenetic distinctiveness demonstrated that strain ISL-6T is distinguishable from the recognized Salegentibacter species. Therefore strain ISL-6T represents a novel species of the genus Salegentibacter, for which the name Salegentibacter salarius sp. nov. is proposed. The type strain is ISL-6T (=KCTC 12974T =CCUG 54355T).
