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

[摘要] A Gram-reaction-negative, oxidase- and catalase-positive, non-gliding motile bacteriun, designated DCY58T, was isolated from a ginseng field in Pocheon Province, South Korea. Colonies of strain DCY58T 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 DCY58T 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 DCY58T contained Q-10 as the predominant ubiquinone. The major cellular fatty acids included Summed Feature 8 (containing C18:1ω6c and/or C18:1ω7c), C14:0 2-OH and C16:0. The DNA G+C content was 65.1 mol%. Furthermore, strain DCY58T differed from other related Sphingomonas species by a number of phenotypic characteristics. On the basis of the evidence presented in this study, strain DCY58T is described as a novel species of genus Sphingomonas, for which the name Sphingomonas ginsengisoli sp. nov., is proposed. The type strain is DCY58T (=KCTC 23762T =JCM 18016T).
