A novel bacterium, designated strain TAPY6 T , was isolated from a freshwater creek in Taiwan. The strain was Gram-stain-negative, strictly aerobic, motile-by-gliding, rod-shaped and formed translucent yellow colonies. Optimal growth occurred at 20-30 °C, pH 6 and in the absence of NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TAPY6 T belonged to the genus Flavobacterium and was most closely related to Flavobacterium succinicans LMG 10402 T (97.3 % sequence similarity) and Flavobacterium glycines Gm-149 T (96.3 %). Strain TAPY6 T contained C15 : 0 and iso-C15 : 0 as the predominant fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, five uncharacterized aminophospholipids, two uncharacterized phospholipids and one uncharacterized aminolipid. The major polyamine was homospermidine. The major isoprenoid quinone was MK-6. The DNA G+C content of the genomic DNA was 39.8 mol%. Phenotypic characteristics of the novel strain also differed from those of the closest related species of the genus Flavobacterium. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain TAPY6 T represents a novel species in the genus Flavobacterium, for which the name Flavobacterium riviphilum sp. nov. is proposed. The type strain is TAPY6 T (=BCRC 81007 T =LMG 29728 T =KCTC 52444 T ).
