A Gram-reaction-negative, strictly aerobic, non-pigmented, non-gliding, rod-shaped bacterium, designated strain BY4T, was isolated from freshwater. Cells were catalase- and oxidase-positive and indole was produced. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain BY4T belonged to the family Flavobacteriaceae and showed 91.6–95.9 % sequence similarities to the most closely related strains. The major respiratory quinone was MK-6 and the major polar lipid was phosphatidylethanolamine. The major polyamine was homospermidine and the major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The DNA G+C content was 30.0 mol%. On the basis of phenotypic, phylogenetic and genotypic features, strain BY4T is suggested to represent a novel species in a new genus within the family Flavobacteriaceae, for which the name Chishuiella changwenlii gen. nov., sp. nov. is proposed. The type strain of this type species is BY4T ( = CGMCC 1.12707T = JCM 19633T). On the basis of data collected from previous and present studies, it is proposed to reclassify Wautersiella falsenii to the genus Empedobacter as the new combination Empedobacter falsenii comb. nov. (type strain NF 993T = CCUG 51536T = CIP 108861T).
