Abstract

A Gram-positive or variable, motile and coccoid or oval-shaped bacterial strain, ASL-17, was isolated from a marine solar saltern of the Yellow Sea in Korea and its exact taxonomic position was investigated by a polyphasic approach. Strain ASL-17 grew optimally at pH 7.0–8.0 and 37 °C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ASL-17 is most closely affiliated phylogenetically to the genus . Strain ASL-17 exhibited 16S rRNA gene sequence similarity values of 97.7–98.6 % to the type strains of recognized species. Interestingly, strain ASL-17 had cell-wall peptidoglycan based on -diaminopimelic acid, unlike other species. It contained MK-7 as the predominant menaquinone. The major fatty acids were anteiso-C, anteiso-C and iso-C. The DNA G+C content was 42.1 mol%. DNA–DNA relatedness data and differential phenotypic properties demonstrated that strain ASL-17 can be differentiated from recognized species. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain ASL-17 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ASL-17 (=KCTC 13144 =CCUG 54360).
