Abstract

A non-motile, rod-shaped and pinkish-red-pigmented bacterium, designated strain WPCB131^T, was isolated from freshwater of Woopo wetland, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that this isolate represents a novel member of the genus Hymenobacter with sequence similarities of 93.2-95.5% to known Hymenobacter species. No other taxa in the phylum Bacteroidetes showed more than 90% sequence similarity to the isolate. Cells were Gram-negative, oxidase-negative and catalase-positive. Optimum growth was observed at pH 6 and 30 °C. The major fatty acids were iso-C_15:0 (34.8%), C_16:1ω5c (15.0%), anteiso-C_17:1 B/ iso-C_17:1 I (14.4%) and C_16:1aw7c/iso-C_15:0 2-OH (13.8%). The DNA G+C content of strain WPCB131^T was 65 mol%. The isolate could be readily distinguished from other Hymenobacter species using a combination of phenotypic characters. On the basis of the polyphasic evidence presented in this study, it is proposed that strain WPCB131^T (= IMSNU 14116^T = KCTC 12533^T = NBRC 101118^T) represents a novel species, Hymenobacter rigui sp. nov.
