Sphingomonas ginsengisoli sp. nov., isolated from soil of a ginseng field

抄録

A Gram-reaction-negative, oxidase- and catalase-positive, non-gliding motile bacteriun, designated DCY58^T, was isolated from a ginseng field in Pocheon Province, South Korea. Colonies of strain DCY58^T were circular, 0.5−1.5 mm in diameter, yellow, and convex on an R2A agar plate after 2 days. The 16S rRNA gene sequence analysis revealed that strain DCY58^T belongs to the family of the Sphingomonadaceae and is most closely related to the species of genus Sphingomonas with similarity levels of 95.7−96.4%. Strain DCY58^T contained Q-10 as the predominant ubiquinone. The major cellular fatty acids included Summed Feature 8 (containing C_18:1ω6c and/or C_18:1ω7c), C_14:0 2-OH and C_16:0. The DNA G+C content was 65.1 mol%. Furthermore, strain DCY58^T differed from other related Sphingomonas species by a number of phenotypic characteristics. On the basis of the evidence presented in this study, strain DCY58^T is described as a novel species of genus Sphingomonas, for which the name Sphingomonas ginsengisoli sp. nov., is proposed. The type strain is DCY58^T (=KCTC 23762^T =JCM 18016^T).
