A Gram-negative, strictly aerobic, yellow-pigmented rod, designated DK69T, was isolated from soil collected from the waste liquid treatment facility of Bafeng Pharmaceutical Company in the city of Enshi, Hubei Province, China. Phylogenetic analysis based on 16S rRNA gene sequences placed strain DK69T in the genus Flavobacterium of the family Flavobacteriaceae . The highest 16S rRNA gene sequence similarities were found with Flavobacterium cauense R2A-7T (96.9 %), Flavobacterium saliperosum AS 1.3801T (96.3 %) and Flavobacterium suncheonense GH29-5T (95.7 %). The major fatty acids (≥5 %) were iso-C15 : 0, iso-C17 : 1ω9c, C15 : 0, iso-C17 : 0 3-OH and iso-C15 : 0 3-OH. The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and one unidentified lipid. The major respiratory quinone was menaquinone-6. The genomic DNA G+C content was 34.4 mol%. Strain DK69T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium enshiense sp. nov. is proposed. The type strain is DK69T ( = CCTCC AB 2011144T = KCTC 23775T). Emended descriptions of the genus Flavobacterium and Flavobacterium cauense , Flavobacterium saliperosum and Flavobacterium suncheonense are also proposed.
