Taeseokella kangwonensis gen. nov., sp. nov., isolated from a freshwater reservoir

A Gram-stain-negative, non-motile and yellow-pigmented bacterium, designated HME8275T, was isolated from freshwater in Korea. The major fatty acids of strain HME8275T were summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c), C16 : 0 and iso-C15 : 0. The only respiratory quinone was MK-7. Polar lipid analysis showed phosphatidylethanolamine, two unidentified aminolipids, two unidentified aminophospholipids and three unidentified polar lipids. The DNA G+C content of strain HME8275T was 37.6 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME8275T formed a lineage within the family Cytophagaceae and was related to Lacihabitans soyangensis HME6675T (92.6 % 16S rRNA gene sequence similarity), Leadbetterella byssophila 4M15T (89.0 %), Fluviimonas pallidilutea TQQ6T (89.7 %) and Emticicia oligotrophica GPTSA100-15T (89.8 %). On the basis of the evidence presented in this study, strain HME8275T represents a novel species of a new genus in the family Cytophagaceae, for which the name Taeseokella kangwonensis, gen. nov., sp. nov. is proposed. The type strain of the type species is HME8275T ( = KACC 16933T = CECT 8198T).
