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 antibioticus (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 357T should be classified as representing a novel species in the genus Lysobacter, for which the name Lysobacter ginsengisoli sp. novo is proposed. The type strain is Gsoil $357^T$ (=KCTC $12602^T$=DSM $18420^T$).
