Abstract

A Gram-negative, rod-shaped, -like bacterial strain, KSL-145, was isolated from an alkaline soil in Korea and subjected to a polyphasic taxonomic investigation. Strain KSL-145 grew optimally at pH 7.5–8.0 and 30 °C without NaCl. It was characterized chemotaxonomically as containing Q-10 as the predominant ubiquinone and C 7 and C as the major fatty acids. The DNA G+C content was 61.8 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain KSL-145 fell within the radiation of the cluster comprising species and . The levels of 16S rRNA gene sequence similarity between strain KSL-145 and the type strains of species and ranged from 95.3 to 98.7 %. The mean DNA–DNA relatedness values between strain KSL-145 and the type strains of and , the closest phylogenetic relatives, were 26 and 15 %, respectively. Strain KSL-145 could be differentiated from species and by differences in several phenotypic characteristics. On the basis of the phenotypic, phylogenetic and genetic data, strain KSL-145 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is KSL-145 (=KCTC 12481=JCM 13476).
