Flavobacterium hauense sp nov., isolated from soil and emended descriptions of Flavobacterium subsaxonicum, Flavobacterium beibuense and Flavobacterium rivuli

A strictly aerobic, Gram-staining-negative, rod-shaped, non-motile, yellow-pigmented bacterial strain BX12(T) 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 strain BX12(T) was most similar to Flavobacterium subsaxonicum WB 4.1-42(T) (95.9%), followed by Flavobacterium beibuense F44-8(T) (95.6%) and Flavobacterium rivuli WB 3.3-2(T) (94.1%). The major fatty acids (>= 5%) were summed feature 3, iso-C-15:0, C-16:0, iso-C-17:0 3-OH, and C-16:0 3-OH. The major polar lipid was phosphatidylethanolamine, and the major respiratory quinine was menaquinone-6. The genomic DNA G+C content was 43.9 mol%. A high number of phenotypic differentiating properties and phylogenetic uniqueness showed that strain BX12(T) represents a novel species of the genus Flavobacterium, for which the name Flavobacterium hauense sp. nov. is proposed. The type strain is BX12(T) (=CCTCC AB 2012197(T)=KCTC 32147(T)). Emended descriptions of Flavobacterium subsaxonicum, Flavobacterium beibuense and Flavobacterium rivuli are also proposed.
