abstract= A bacterial strain, designated TTM-43T, was isolated from a water sample taken from the Caohu River in Taiwan and characterized using a polyphasic taxonomic approach. Cells of strain TTM-43T were Gram-stain-negative, strictly aerobic, motile by gliding, rod-shaped and surrounded by a thick capsule. The strain formed bright-yellow colonies. Growth occurred at 15–30 °C (optimum, 20 °C), at pH 5–9 (optimum, pH 6) and with 0–0.3 % NaCl (optimum growth in the absence of added NaCl). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TTM-43T belonged to the genus Flavobacterium and was most closely related to Flavobacterium terrae R2A1-13T, with 97.8 % sequence similarity. Strain TTM-43T contained iso-C15 : 0 (24.9 %), iso-C15 : 1 G (12.6 %), summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0; 12.2 %), iso-C17 : 0 3-OH (10.9 %), iso-C15 : 0 3-OH (7.3 %) and iso-C16 : 0 (6.7 %) as the predominant fatty acids. The major isoprenoid quinone was MK-6. The polar lipid profile consisted of phosphatidylethanolamine and several uncharacterized aminophospholipids and phospholipids. The major polyamine was homospermidine. The genomic DNA G+C content of strain TTM-43T was 31 mol%. DNA–DNA relatedness of strain TTM-43T with respect to type strains of recognized species of the genus Flavobacterium was less than 70 %. On the basis of phylogenetic inference and phenotypic data, strain TTM-43T should be assigned to a novel species, for which the name Flavobacterium brevivitae sp. nov. is presented. The type strain is TTM-43T ( = BCRC 80913T = KCTC 42744T = LMG 29004T).,
