A Gram-negative, rod-shaped, yellow pigmented bacterium, strain NJ-26^T, was isolated from sediment of the eutrophicated Guanting Reservoir in Beijing, China. A phylogenetic analysis based on 16S rRNA gene sequences placed strain NJ-26^T within the genus Flavobacterium in the family Flavobacteriaceae. The highest sequence similarity was found with Flavobacterium cucumis R2A45-3^T (97.7 %). The major fatty acids (>5 %) of the isolate were iso-C_{15 : 0}, iso-C_{17 : 1}9c, C_{15 : 0}, iso-C_{17 : 0} 3-OH, iso-C_{15 : 1} G and iso-C_{15 : 0} 3-OH. The G+C content of the genomic DNA was 40.6 mol%. The DNA–DNA relatedness value with F. cucumis R2A45-3^T was 5.4 %. Molecular and phenotypic data suggest that strain NJ-26^T represents a novel species within the genus Flavobacterium, for which the name Flavobacterium cheniae sp. nov. is proposed. The type strain is NJ-26^T (=CGMCC 1.6844^T =NBRC 103934^T).

Maximum-parsimony and minimum-evolution phylogenetic trees based on 16S rRNA gene sequences are available as supplementary material with the online version of this paper.
