Lacihabitans soyangensis gen. nov., sp. nov., a new member of the family Cytophagaceae, isolated from a freshwater reservoir.

ABSTRACT

A Gram-staining-negative, non-motile and orange-pigmented bacterium, designated strain HME6675(T), was isolated from freshwater of a reservoir in Korea. The major fatty acids of strain HME6675(T) were iso-C15  0 (33.4 %) and summed feature 3 (comprising C16  1ω6c and/or C16  1ω7c; 31.3 %). The major respiratory quinone was MK-7. The polar lipids were phosphatidylethanolamine, one unidentified aminolipid, one unidentified aminophospholipid and three unidentified polar lipids. The DNA G+C content of strain HME6675(T) was 37.7 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME6675(T) formed a lineage within the family Cytophagaceae and was related to Leadbetterella byssophila 4M15(T) (93.0 % sequence similarity), Fluviimonas pallidilutea TQQ6(T) (90.6 %) and Emticicia oligotrophica GPTSA100-15(T) (89.1 %). On the basis of the evidence presented in this study, strain HME6675(T) represents a novel genus and species of the family Cytophagaceae, for which the name Lacihabitans soyangensis gen. nov., sp. nov. is proposed. The type strain of Lacihabitans soyangensis is HME6675(T) ( = KCTC 23259(T) = CECT 7826(T)).
