Abstract

A Gram-negative, non-spore-forming, rod-shaped bacterial strain, K107, was isolated from sludge collected from a textile dye works in Korea and its taxonomic position was investigated by means of a polyphasic analysis. Strain K107 contained Q-10 as the predominant ubiquinone. The major fatty acids (>10 % of total fatty acids) were C 7 and C 2-OH. The DNA G+C content was 57.0 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain K107 was closely related to the genera , and . Strain K107 exhibited 16S rRNA gene sequence similarity values of 96.3–97.1 % with respect to the type strains of two species and 94.8–96.8 % with respect to members of the genera and . A phylogenetic analysis based on gene sequences showed that strain K107 forms a distinct phylogenetic lineage within the . The gene sequence of strain K107 showed similarity values of 84.5 % with respect to type strains of species and values of 77.6–83.1 % with respect to members of the genera , and . Strain K107 could be differentiated from phylogenetically related genera by differences in phenotypic properties and fatty acid profiles. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain K107 represents a novel genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain of is strain K107 (=KCTC 12981 =CCUG 54520).
