Strain DCY45(T) was isolated from soil of a ginseng field in Pocheon Province, Korea. Strain DCY45(T) was Gram-negative, oxidase- and catalase-positive, motile and rod-shaped and produced yellow pigments on R2A agar. The organism grew optimally at 30 °C and at pH 7.0. The G+C content of the genomic DNA was 65.4 mol%. The predominant respiratory quinone was Q-8. The major fatty acids were iso-C(17 : 1)ω9c, iso-C(16 : 0) and iso-C(15 : 0). Phylogenetic analysis based on the 16S rRNA gene sequence was used to determine the taxonomic position of strain DCY45(T), which is most closely related to species of the genus Rhodanobacter, with similarity levels of 96.0-98.4 %; DNA-DNA relatedness with related strains was lower than 60 %. Strain DCY45(T) differed significantly from related type strains in phenotypic characteristics. On the basis of these phenotypic, genotypic and chemotaxonomic studies, strain DCY45(T) represents a novel species of the genus Rhodanobacter, for which the name Rhodanobacter soli sp. nov. is proposed. The type strain is DCY45(T) (=KCTC 22620(T) =JCM 16126(T)).
