Abstract
A flexirubin-type yellow-pigmented, non-gliding, non-flagellated, gram-negative bacterium strain, designated F3T, was isolated from a drilling core sample of the Qiangtang basin, Qinghai-Tibetan plateau, China. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain F3T belongs to the genus Flavobacterium, with the highest 16S rRNA gene sequence similarity to the Flavobacterium noncentrifugens CGMCC 1.10076T (94.92 %). Strain F3T grew optimally at temperature about 20 °C, at pH about 7.0–8.0, at NaCl concentration 0 % (w/v). The DNA G+C content of the isolate was 35.5 mol%. The major polar lipid was phosphatidylethanolamine, predominant cellular fatty acids of the strain was iso-C15:0 (22.02 %), while the major menaquinone was menaquinone 6. Due to the phenotypic and genetic distinctiveness and several other characteristic studied in this article, we consider F3T as a novel species of the genus Flavobacterium, and propose to name it Flavobacterium qiangtangensis sp. nov. The type strain is F3T (=CGMCC 1.12706T = JCM 19739T).
