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

A Gram-stain-negative, non-motile and yellow-pigmented bacterium; designated HME8275(T), was isolated from freshwater in Korea. The major fatty acids of strain HME8275(T) were summed feature 3 (comprising C-16 :1 omega 6c and/or C-16 :1 omega 7C), C-16 : 0 and iso-C-15 : 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 HME8275(T) was 37.6 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME8275(T) formed a lineage within the family Cytophagaceae and was related to Lacihabitans soyangensis HME6675(T) (92.6 % 16S rRNA gene sequence similarity), Leadbetterella byssophila 4M15(T) (89.0 %), Fluviimonas pallidilutea TQQ6(T) (89.7 %) and Emticicia oligotrophica GPTSA100-15(T) (89.8 %). On the basis of the evidence presented in this study, strain HME8275(T) 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 HME8275(T) (=KACC 16933(T)=CECT 8198(T)).
