A Gram-negative, non-motile, rod-shaped bacterial strain, DS-58(T), was isolated from a soil sample from Dokdo, an island of Korea, and its taxonomic position was investigated. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-58(T) fell within the family Xanthomonadaceae. The isolate showed 96.9 % 16S rRNA gene sequence similarity with its closest phylogenetic neighbour, Lysobacter niastensis GH41-7(T), and 93.4-95.7 % 16S rRNA gene sequence similarity with other members of the genus Lysobacter. Strain DS-58(T) contained Q-8 as the predominant ubiquinone and iso-C(16 : 0), iso-C(15 : 0) and iso-C(17 : 1)ω9c as the major fatty acids. The DNA G+C content was 68.1 mol%. Strain DS-58(T) could be distinguished phenotypically from type strains of closely related species of the genus Lysobacter and phylogenetically from all members of the genus Lysobacter. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DS-58(T) is considered to represent a novel species of the genus Lysobacter, for which the name Lysobacter dokdonensis sp. nov. is proposed. The type strain is DS-58(T) ( = KCTC 12822(T) = DSM 17958(T)).
一株革兰氏阴性、非运动、杆状的细菌菌株 DS-58(T) 从韩国独岛的土壤样本中分离出来，并对其分类地位进行了研究。基于 16S rRNA 基因序列的系统发育分析表明，菌株 DS-58(T) 属于黄单胞菌科。该分离株与最接近的亲缘种 Lysobacter niastensis GH41-7(T) 的 16S rRNA 基因序列相似性为 96.9%，与其他 Lysobacter 属成员的 16S rRNA 基因序列相似性为 93.4-95.7%。菌株 DS-58(T) 含有 Q-8 作为主要的泛醌，以及 iso-C(16 : 0)、iso-C(15 : 0)和 iso-C(17 : 1)ω9c 作为主要的脂肪酸。DNA G+C 含量为 68.1mol%。菌株 DS-58(T) 在表型、化学分类和系统发育上可与 Lysobacter 属的密切相关种的模式菌株区分开来，也可与 Lysobacter 属的所有成员区分开来。基于表型、化学分类和系统发育数据，菌株 DS-58(T) 被认为代表了 Lysobacter 属的一个新种，建议将其命名为 Lysobacter dokdonensis sp. nov.。其模式菌株为 DS-58(T)（=KCTC 12822(T)=DSM 17958(T)）。
