Abstract

A Gram-negative, aerobic bacterium, designated CG20106, was isolated from the surface tissues of rusty root lesions of Korean ginseng. Phylogenetic analysis of the 16S rRNA gene sequence revealed that this isolate represents a hitherto unknown subline within the genus . Strain CG20106 was catalase- and oxidase-positive, motile and rod-shaped. The overall phenotypic features of the ginseng isolate were similar to those of , and . However, several physiological and chemotaxonomic properties can be weighted to distinguish the isolate from these organisms. The major fatty acids were C 7 and/or iso-C 2-OH (summed feature 3, 36·4±0·4 %), C (27·5±0·7 %) and C 7 (19·4±0·2 %). The DNA G+C content was 61·4 mol%. On the basis of the polyphasic results revealed in this study, the name sp. nov. is proposed for strain CG20106. The type strain is CG20106 (=IMSNU 14100=CIP 108524=KCTC 12330).
