A non-motile, pale-yellow bacterium, designated strain HMD1056(T), was isolated from an artificial lake located within the campus of Hankuk University of Foreign Studies, Yongin, Korea. The major fatty acids were summed feature 3 (iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c; 49.1 %) and iso-C(15 : 0) (22.4 %). The major respiratory quinone was MK-7. The DNA G+C content was 46.9 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HMD1056(T) formed a lineage within the genus Mucilaginibacter and was closely related to the type strains of Mucilaginibacter ximonensis (95.4 % sequence similarity), Mucilaginibacter kameinonensis (94.5 %) and Mucilaginibacter paludis (93.4 %). On the basis of the evidence presented in this study, strain HMD1056(T) represents a novel species of the genus Mucilaginibacter, for which the name Mucilaginibacter myungsuensis sp. nov. is proposed. The type strain is HMD1056(T) ( = KCTC 22746(T) = CECT 7550(T)).
从韩国龙仁市韩国外国语大学校园内的人工湖分离出一株无运动性、淡黄色的细菌,命名为菌株HMD1056(T)。主要脂肪酸为总和特征3(异-C(15:0) 2-OH和/或C(16:1)ω7c;49.1%)和异-C(15:0)(22.4%)。主要呼吸醌为MK-7。DNA G+C含量为46.9 mol%。基于16S rRNA基因序列构建的系统发育树表明,菌株HMD1056(T)在黏液杆菌属内形成一个分支,与西蒙黏液杆菌模式菌株(序列相似性95.4%)、龟野黏液杆菌模式菌株(94.5%)和沼泽黏液杆菌模式菌株(93.4%)密切相关。根据本研究提供的证据,菌株HMD1056(T)代表黏液杆菌属的一个新物种,为此提出新名称明秀黏液杆菌(Mucilaginibacter myungsuensis sp. nov.)。模式菌株为HMD1056(T)(=KCTC 22746(T)=CECT 7550(T))。
