Abstract

A Gram-positive, non-motile and coccoid-, short rod- or rod-shaped bacterial strain, ISL-16, was isolated from a marine solar saltern in Korea and its taxonomic position was investigated using a polyphasic taxonomic approach. Strain ISL-16 grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-16 joined the cluster comprising species of the genus . Its 16S rRNA gene sequence contained the same signature nucleotides as those defined for the genus . Strain ISL-16 exhibited 16S rRNA gene sequence similarity values of 96.9–98.2 % to the type strains of species of the genus . Strain ISL-16 contained MK-8 and MK-7 as the predominant menaquinones and anteiso-C, C 7 alcohol and anteiso-C as the major fatty acids. The DNA G+C content was 48.3 mol%. DNA–DNA relatedness values between strain ISL-16 and the type strains of species of the genus were 15–28 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, enabled strain ISL-16 to be differentiated from recognized species of the genus . On the basis of the data presented, strain ISL-16 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ISL-16 (=KCTC 13584=CCUG 57753). An emended description of the genus is also given.
