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(17:1)ω9c 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(16:1)ω7c, C(16:1)ω6c 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.
