Pseudomonas panacis sp. nov., isolated from the surface of rusty roots of Korean ginseng.
A Gram-negative, aerobic bacterium, designated CG20106(T), 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 Pseudomonas. Strain CG20106(T) was catalase- and oxidase-positive, motile and rod-shaped. The overall phenotypic features of the ginseng isolate were similar to those of Pseudomonas cedrina, Pseudomonas migulae and Pseudomonas azotoformans. However, several physiological and chemotaxonomic properties can be weighted to distinguish the isolate from these organisms. The major fatty acids were C(16:1)omega7c and/or iso-C(15:0) 2-OH (summed feature 3, 36.4+/-0.4%), C(16:0) (27.5+/-0.7%) and C(18:1)omega7c (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 Pseudomonas panacis sp. nov. is proposed for strain CG20106(T). The type strain is CG20106(T) (=IMSNU 14100(T)=CIP 108524(T)=KCTC 12330(T)).
