Two novel bacterial strains BT178 and BT635 were isolated from soil collected in Gyeonggi province, Republic of Korea. Both strains were Gram-negative, rod-shaped circular, and had convex, glistening, pink-colored colonies. Phylogenetic analysis based on 16S rRNA gene sequences showed that each of the strains BT178 and BT635 formed an individual lineage within the genus Hymenobacter (family Hymenobacteraceae, order Cytophagales, class Cytophagia, phylum Bacteroidetes). The 16S rRNA gene sequence similarity between the two strains BT178 and BT635 were 97.7%. Both strains had Q-7 as the major respiratory quinone and phosphatidylethanolamine (PE) as the major polar lipids. The main cellular fatty acids of strain BT178 were iso-C, anteiso-C, and those of strain BT635 were iso-C and Summed Feature 4 (iso-C I / anteiso-C B). Based on the result of polyphasic taxonomic analysis, two novel species, Hymenobacter lucidus BT178 (= KCTC 72333 = NBRC 115442) and Hymenobacter nitidus BT635 (= KACC 21904 = NBRC 115443) were proposed.
从韩国京畿道采集的土壤中分离出两株新型细菌菌株BT178和BT635。两株菌株均为革兰氏阴性、杆状圆形，菌落凸起、有光泽、呈粉红色。基于16S rRNA基因序列的系统发育分析表明，菌株BT178和BT635各自在嗜皮菌属（嗜皮菌科、噬纤维菌目、噬纤维菌纲、拟杆菌门）内形成一个单独的谱系。菌株BT178和BT635之间的16S rRNA基因序列相似性为97.7%。两株菌株均以Q-7作为主要呼吸醌，以磷脂酰乙醇胺（PE）作为主要极性脂质。菌株BT178的主要细胞脂肪酸为异-C、anteiso-C，菌株BT635的主要细胞脂肪酸为异-C和总和特征4（异-C I / anteiso-C B）。基于多相分类分析结果，提出了两个新物种，即明亮嗜皮菌BT178（=KCTC 72333=NBRC 115442）和闪亮嗜皮菌BT635（=KACC 21904=NBRC 115443）。
