A Gram-negative, aerobic, rod-shaped, nonspore-forming bacterial strain, designated Gsoil 357T, 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-C16:0, iso-C17:1 9c, and iso-C15:0 as the major fatty acids. The G+C content of the genomic DNA was 69.3mol%. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain Gsoil 357T was most closely related to Lysobacter gummosus (97.6%) and Lysobacter antibioticus (97.6%). However, the DNA-DNA relatedness value between strain Gsoil 357T 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. nov. is proposed. The type strain is Gsoil 357T (=KCTC 12602T=DSM 18420T).
从韩国抱川市人参田土壤样本中分离出一株革兰氏阴性、需氧、杆状、不产芽孢的细菌菌株，命名为Gsoil 357T。该菌株以Q-8作为主要泛醌，以异-C16:0、异-C17:1 9c和异-C15:0作为主要脂肪酸。基因组DNA的G+C含量为69.3mol%。基于16S rRNA基因序列的系统发育分析表明，菌株Gsoil 357T与黏液溶杆菌（97.6%）和抗生溶杆菌（97.6%）关系最为密切。然而，菌株Gsoil 357T与其系统发育关系最密切的近缘菌株之间的DNA-DNA相关性值小于17%。基于其表型特征和系统发育独特性，菌株Gsoil 357T应被归类为溶杆菌属中的一个新物种，为此提出名为人参溶杆菌（Lysobacter ginsengisoli sp. nov.）。模式菌株为Gsoil 357T（=KCTC 12602T=DSM 18420T）。
