A Gram-negative, rod-shaped Flavobacterium-like bacterial strain, DS-6T, was isolated from soil from the island of Dokdo, Korea, and subjected to a polyphasic taxonomic study. Strain DS-6T grew optimally at pH 7.0 and 25 degrees C in the presence of 0-0.5 % (w/v) NaCl. It contained MK-6 as the predominant menaquinone and iso-C15:0 and iso-C17:0 3-OH as the major fatty acids. The DNA G+C content was 36.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DS-6T belonged to the genus Flavobacterium. Levels of 16S rRNA gene sequence similarity between strain DS-6T and the type strains of Flavobacterium species were below 95.4 %. Strain DS-6T differed from some phylogenetically related Flavobacterium species in several phenotypic characteristics. On the basis of phenotypic and phylogenetic distinctiveness, DS-6T (=KCTC 12542T=CIP 108840T) was classified in the genus Flavobacterium as the type strain of a novel species, for which the name Flavobacterium soli sp. nov. is proposed.
从韩国独岛的土壤中分离出一株革兰氏阴性、杆状、类黄杆菌属细菌菌株DS-6T,并对其进行了多相分类研究。菌株DS-6T在pH 7.0和25℃、0-0.5%(w/v)NaCl存在的条件下生长最佳。它以MK-6作为主要的甲基萘醌,以异-C15:0和异-C17:0 3-OH作为主要脂肪酸。DNA G+C含量为36.9 mol%。基于16S rRNA基因序列的系统发育分析表明,菌株DS-6T属于黄杆菌属。菌株DS-6T与黄杆菌属各模式菌株之间的16S rRNA基因序列相似性水平低于95.4%。菌株DS-6T在几个表型特征上与一些系统发育相关的黄杆菌属物种不同。基于表型和系统发育的独特性,DS-6T(=KCTC 12542T=CIP 108840T)被归类为黄杆菌属中的一个新物种的模式菌株,为此提出了新名称黄杆菌独岛种(Flavobacterium soli sp. nov.)。
