Mucilaginibacter myungsuensis sp. nov., isolated from a mesotrophic artificial lake

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)).
