Emticicia aquatica sp nov., a species of the family Cytophagaceae isolated from fresh water

초록

A Gram-staining-negative, non-gliding, orange-pigmented bacterial strain, designated HMF2925(T), was isolated from fresh water in Korea. The phylogenetic tree based on 16S rRNA gene sequences showed that strain HMF2925(T) formed a distinct lineage within the genus. Emticicia. Strain HMF2925(T) was closely related to Emticicia oligotrophica DSM 17448(T) (95.5 %) and Emticicia ginsengisoli Gsoil 085(T) (94.1 %). The major fatty acids of strain HMF2925(T) were summed feature 3 (C-16 (:) (1)omega 6c and/or C-16 : 1 omega 7c), iso-C-15 : 0, C-16 : 1 omega 5c and C-16 : 0.The major polar lipids of strain HMF2925(T) were phosphatidylethanolamine, phosphatidylinositol, diphosphatidylglycerol, phosphatidylglycerol, an unidentified glycolipid, two unidentified amino lipids and three unidentified polar lipids. The DNA G+C content of strain HMF2925(T) was 36.5 mol%. On the basis of the evidence presented in this study, strain HMF2925(T) represents a novel species of the genus Emticicia, for which the name Emticicia aquatica sp. nov. is proposed. The type strain is HMF2925(T) (=KCTC 42574(T)=CECT 8858(T)).
