abstract= Strain LLJ-11T, isolated from water sampled from a freshwater stream in Taiwan, was characterized using a polyphasic taxonomy approach. Cells of strain LLJ-11T were Gram-stain-negative, strictly aerobic, motile by gliding, rod-shaped and formed translucent yellow colonies. Optimal growth occurred at 25 °C, pH 7 and 0 % NaCl. Phylogenetic analyses based on 16S rRNA gene sequences and coding sequences of 92 protein clusters indicated that strain LLJ-11T is affiliated with species in the genus Flavobacterium . Strain LLJ-11T was most closely related to Flavobacterium amniphilum KYPY10T with 98.0 % 16S rRNA gene sequence identity. The DNA–DNA relatedness of strain LLJ-11T with respect to Flavobacterium species was less than 35 %. Average nucleotide identity and digital DNA–DNA hybridization values between strain LLJ-11T and the type strains of other closely related Flavobacterium species were 70.0–76.3 % and 21.1–23.9 %, respectively. Strain LLJ-11T contained iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH, summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0) as the predominant fatty acids. The major isoprenoid quinone was MK-6. The polar lipid profile consisted of phosphatidylethanolamine, three uncharacterized aminophospholipids and two uncharacterized phospholipids. The major polyamine was homospermidine. The DNA G+C content was 34.8 mol%. On the basis of the phylogenetic inference and phenotypic data, strain LLJ-11T is considered a representative of a novel species within the genus Flavobacterium . The name Flavobacterium amnicola sp. nov. is proposed, with strain LLJ-11T (=BCRC 81124T=LMG 30599T=KCTC 62514T) as the type strain.,
