A Gram-staining-negative, yellow-pigmented bacterial strain, motile by gliding, designated HME7102(T), was isolated from lagoon water in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HME7102(T) formed a distinct lineage within the genus Flavobacterium. Strain HME7102(T) was closely related to Flavobacterium cheniae NJ-26(T) (94.5 %), Flavobacterium dongtanense LW30(T) (94.4 %) and Flavobacterium gelidilacus LMG 21477(T) (94.2 %). The major fatty acids of strain HME7102(T) were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major polyamine was homospermidine and the major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and two unidentified polar lipids. The DNA G+C content of strain HME7102(T) was 36.5 mol%. On the basis of the evidence presented in this study, strain HME7102(T) represents a novel species of the genus Flavobacterium, for which the name Flavobacterium jumunjinense sp. nov. is proposed. The type strain is HME7102(T) ( = KCTC 23618(T) = CECT 7955(T)). Emended descriptions of F. cheniae, F. dongtanense and F. gelidilacus are also proposed.
一株革兰氏阴性、呈黄色的细菌菌株 HME7102(T)，通过滑行运动进行运动，从韩国泻湖水中分离得到。基于 16S rRNA 基因序列的系统发育树表明，菌株 HME7102(T)在黄杆菌属内形成了一个独特的分支。菌株 HME7102(T)与费氏黄杆菌 NJ-26(T)（94.5%）、东滩黄杆菌 LW30(T)（94.4%）和凝胶冷杆菌 LMG 21477(T)（94.2%）最为密切相关。菌株 HME7102(T)的主要脂肪酸为 iso-C15:0、iso-C15:1 G、iso-C17:0 3-OH 和 iso-C15:0 3-OH。主要多胺为腐胺，主要极性脂为磷脂酰乙醇胺、一种未鉴定的胺脂和两种未鉴定的极性脂。菌株 HME7102(T)的 DNA G+C 含量为 36.5 mol%。基于本研究提供的证据，菌株 HME7102(T)代表黄杆菌属的一个新种，命名为巨济黄杆菌（Flavobacterium jumunjinense）sp. nov.。其模式菌株为 HME7102(T)（ = KCTC 23618(T) = CECT 7955(T)）。还对费氏黄杆菌、东滩黄杆菌和凝胶冷杆菌的描述进行了修正。
