Abstract
A strictly aerobic, Gram-staining-negative, rod-shaped, non-motile, yellow-pigmented bacterial strain, designated BX12T, was isolated from soil collected from the peak area of Wudang Mountain in the city of Shiyan, Hubei province, China. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain BX12T was most closely related to
Flavobacterium subsaxonicum
WB 4.1-42T (95.9 % 16S rRNA gene sequence similarity), followed by
Flavobacterium beibuense
F44-8T (95.6 %) and
Flavobacterium rivuli
WB 3.3-2T (94.1 %). The major fatty acids (≥5 %) of strain BX12T were summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH, and C16 : 0 3-OH. The major polar lipid was phosphatidylethanolamine, and the major respiratory quinone was menaquinone-6. The genomic DNA G+C content was 43.9 mol%. On the basis of a high number of phenotypic differentiating properties and phylogenetic uniqueness, strain BX12T represents a novel species of the genus
Flavobacterium
for which the name
Flavobacterium
hauense sp. nov. is proposed. The type strain is BX12T ( = CCTCC AB 2012197T = KCTC 32147T). Emended descriptions of
Flavobacterium subsaxonicum
,
Flavobacterium beibuense
and
Flavobacterium rivuli
are also proposed.
