A Gram-stain-negative, aerobic and rod-shaped bacterial strain, designated HME7524(T), was isolated from freshwater of Gyeong-an stream in Korea. A phylogenetic tree based on 16S rRNA gene sequences showed that strain HME7524(T) formed a distinct lineage within the genus Flavobacterium and exhibited high sequence similarity with Flavobacterium chungangense CJ7(T) (96.9 %), Flavobacterium aquidurense WS-1.1.56(T) (96.9 %), Flavobacterium tructae 435-08T (96.9%) and Flavobacterium granuli Kw05(T) (96.9 %). The major fatty acids of strain HME7524(T) were iso-C-15:0 (26.5%) and summed feature 3 (comprising C(16:1 omega)6c and/or C-16:1 omega 7c; 17.4%). The major polar lipids were phosphatidylethanolamine, two unidentified aminolipids and three unidentified polar lipids. The major respiratory quinone was MK-6. The DNA G-FC content of strain HME7524(T) was 34.2 mol%. On the basis of the evidence presented in this study, strain HME7524(T) represents a novel species of the genus Flavobacterium, for which the name Flavobacterium gyeonganense sp. nov., is proposed. The type strain is HME7524(T) (=KACC 17688(T)=CECT 8365(T)). Emended descriptions of Flavobacterium chungangense, Flavobacterium aquidurense, Flavobacterium tructae and Flavobacterium granuli are also provided.
