Rhodanobacter soli sp. nov., isolated from soil of a ginseng field

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_17:1ω9c, 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).
