Lysobacter ginsengisoli sp nov., a novel species isolated from soil in Pocheon Province, South Korea

Abstract

A Gram-negative, aerobic, rod-shaped, nonspore-forming bacterial strain, designated Gsoil 357(T), was isolated from soil sample of a ginseng field in Pocheon Province (South Korea). The isolate contained Q-8 as the predominant ubiquinone and iso-C-16.0, iso-C-17:1 omega 9c, and iso-C-15:0 as the major fatty acids. The G+C content of the genomic DNA was 69.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Gsoil 357(T) was most closely related to Lysobacter gummosus (97.6%) and Lysobacter antibiotics (97.6%). However, the DNA-DNA relatedness value between strain Gsoil 357(T) and its phylogenetically closest neighbors was less than 17%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 357 T should be classified as representing a novel species in the genus Lysobaeter, for which the name Lysobacter ginsengisoli sp. nov. is proposed. The type strain is Gsoil 357(T) (=KCTC 12602(T)=DSM 18420(T)).
