A non-motile, rod-shaped and pale-pink bacterium, designated strain WS71(T), was isolated from freshwater collected from the Woopo Wetland (Republic of Korea). Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were summed feature 3 (comprising C-16 : 1 omega 6c and/or C-16 : 1 omega 7c), iso-C-17 : 0 3-OH, C-16 : 0 and iso-C-15 : 0. The strain contained menaquinone 7 (MK-7) and the DNA G+C content was 39.4 +/- 0.4 mol%. The major polar lipids were phosphatidylethanolamine and an unknown aminophospholipid. A phylogenetic tree based on 16S rRNA gene sequences showed that WS71(T) forms an evolutionary lineage within the radiation enclosing the members of genus Mwucilaginibacter with Mucilaginibacter. soyangensis HME6664(T) as its nearest neighbor (98.3% sequence similarity). DNA-DNA relatedness between WS71(T) and M. soyangensis HME6664(T) was 61.3 +/- 1.0 %. A number of phenotypic characteristics distinguished WS71(T) from the other members of the genus Mucilaginibacter. On the basis of the evidence presented in this study, WS71(T) represents a novel species, for which the name Mucilaginibacterpuniceus sp. nov. is proposed. The type strain is WS71(T) (=KCTC 32270(T)=JCM 19495(T)).
