Abstract

A Gram-positive or Gram-variable, motile, moderately halophilic, rod-shaped bacterial strain, ISL-50, was isolated from a marine solar saltern in Korea and subjected to a polyphasic taxonomic study. Strain ISL-50 grew optimally at pH 7.0–8.0 and 37 °C in the presence of 8 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain ISL-50 belonged to the genus . Strain ISL-50 exhibited 16S rRNA gene sequence similarity values of 95.3–98.2 % with respect to the type strains of recognized species. The cell-wall peptidoglycan was based on -diaminopimelic acid, the predominant menaquinone was MK-7 and the major fatty acids were anteiso-C and anteiso-C. The DNA G+C content was 39.3 mol%. DNA–DNA relatedness data and differential phenotypic properties revealed that strain ISL-50 was distinguishable from the recognized species. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain ISL-50 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ISL-50 (=KCTC 13145=CCUG 54358).
