Flavobacterium ummariense sp. nov., isolated from hexachlorocyclohexane-contaminated soil, and emended description of Flavobacterium ceti Vela et al. 2007

A Gram-negative, strictly aerobic, yellow bacterial strain, designated DS-12^T, was isolated from hexachlorocyclohexane-contaminated soil in Lucknow, Uttar Pradesh, India. Strain DS-12^T showed the highest 16S rRNA gene sequence similarity with Flavobacterium ceti 454-2^T (94.2 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-12^T belonged to the genus Flavobacterium. Strain DS-12^T produced flexirubin-type pigments. Gliding motility was not observed. The major fatty acids of strain DS-12^T were iso-C_15 : 0 (48.0 %), summed feature 9 (comprising iso-C_17 : 1ω9c and/or C_16 : 0 10-methyl; 19.3 %), iso-C_17 : 0 3-OH (8.5 %) and summed feature 3 (comprising one or more of C_16 : 1ω7c, C_16 : 1ω6c and iso-C_15 : 0 2-OH; 7.2 %). The only respiratory quinone was menaquinone-6 and the major polyamine was homospermidine. Strain DS-12^T contained phosphatidyldimethylethanolamine, phosphatidylserine, phosphatidylethanolamine, one unknown phospholipid and one unknown aminolipid. The DNA G+C content was 37.4 mol%. Phylogenetic inference and phenotypic properties indicated that strain DS-12^T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium ummariense sp. nov. is proposed. The type strain is DS-12^T ( = CCM 7847^T  = MTCC 10766^T). An emended description of Flavobacterium ceti is also given.
