Abstract

An aerobic, Gram-stain-negative, oxidase-negative, catalase-positive, non-motile, non-spore-forming, rod-shaped, light pink-pigmented bacterium, designated strain R135, was isolated from soil in Hwaseong, South Korea. Flexirubin-type pigments were absent. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that strain R135 formed a lineage within the family of the phylum It was distinct from various species of the genus including DS-57 (98.13 % sequence similarity), NWER-II11 (97.76 %), 15-52 (97.71 %), KACC 16221 (97.37 %), CG-GP80 (97.24 %), 15-51 (97.23 %) and DS-27 (97.09 %). The major isoprenoid quinone was menaquinone-7 (MK-7), and the major polar lipid was phosphatidylethanolamine. The major cellular fatty acids were summed feature 3 (C 7 and/or C 6), iso-C, iso-C3-OH and C. The DNA G+C content of strain R135 was 40.4 mol%. Levels of DNA–DNA hybridization similarities between strain R135and other members of the genus ranged from 25 % to 43 %. On the basis of phenotypic, genotypic and phylogenetic analysis, strain R135 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is R135 (=KEMB 9005-332=KACC 18452=JCM 31010).
