Abstract

Strain TAPW14 was isolated from a freshwater creek in Taiwan. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TAPW14 belonged to the genus Flavobacterium and was most closely related to Flavobacterium akiainvivens IK-1 (96.6 % sequence identity) and Flavobacterium hauense BX12 (96.0 %) and less than 96 % sequence similarity to other members of the genus. Cells of strain TAPW14 were Gram-negative, strictly aerobic, motile by gliding, rod-shaped and formed white colonies. Optimal growth occurred at 20 °C, pH 7 and in the presence of 0.5 % NaCl. Strain TAPW14 contained summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c), iso-C15 : 0 and C16 : 0 as the predominant fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, three uncharacterized aminophospholipids, one uncharacterized phospholipid and one uncharacterized lipid. The major polyamine was homospermidine. The major isoprenoid quinone was MK-6. The DNA G+C content of the genomic DNA was 46.0 mol%. On the basis of the phylogenetic inference and phenotypic data, strain TAPW14 should be classified as a novel species, for which the name Flavobacteriumniveum sp. nov. is proposed. The type strain is TAPW14 (=BCRC 81055=LMG 30057=KCTC 52808).
