| Abstract |
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(18:1ω)6c and/or C(18:1ω)7c), 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)).
