A Gram-variable-staining, motile and coccoid-, ovoid- or rod-shaped bacterium, strain ISL-25, was isolated from a marine solar saltern of the Yellow Sea, Korea, and its taxonomic position was investigated by means of a polyphasic study. Strain ISL-25 grew optimally at pH 7.0–8.0 and 30–37 °C. Strain ISL-25 contained -diaminopimelic acid as the cell-wall peptidoglycan, MK-7 as the predominant menaquinone and anteiso-C, anteiso-C and iso-C as the major fatty acids. The DNA G+C content was 49.3 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ISL-25 belongs to the genus . The similarity values between the 16S rRNA gene sequence of strain ISL-25 and those of the type strains of the three currently recognized species were 97.6–98.3 %. Mean DNA–DNA relatedness values between strain ISL-25 and the type strains of the genus were 9–15 %. Differential phenotypic properties of strain ISL-25, together with the phylogenetic and genetic distinctiveness, revealed that this strain could be differentiated from other species. Therefore, strain ISL-25 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is ISL-25 (=KCTC 13260=CCUG 56755).
