Abstract

A novel gammaproteobacterium, designated LnR5-47, was isolated from soil of a ginseng field in Liaoning province, China. The isolate was a Gram-negative, aerobic, non-motile, non-spore-forming rod. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LnR5-47 belonged to the genus . The isolate was most closely related to GR17-7, GP18-1, Gsoil 3046, DCY45, JS12-10 and IAM 15069 (98.0, 97.9, 97.7, 97.3, 97.2 and 97.1 % 16S rRNA gene sequence similarity, respectively). Chemotaxonomic data (Q-8 as the predominant ubiquinone, and iso-C, iso-Cω9 and iso-C as the major fatty acids) also supported the affiliation of strain LnR5-47 with the genus . However, DNA–DNA relatedness between strain LnR5-47 and its closest phylogenetic neighbours was <25.8 %. Moreover, physiological and biochemical tests phenotypically differentiated the isolate from other members of the genus . Therefore, strain LnR5-47 represents a novel species, for which the name sp. nov. is proposed; the type strain is LnR5-47 ( = KACC 12826 = KCTC 22232 = LMG 24460).
