Abstract

A non-motile, rod-shaped and pinkish-red-pigmented bacterium, designated strain WPCB131, 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 with sequence similarities of 93.2–95.5 % to known species. No other taxa in the phylum 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 (34.8 %), C 5 (15.0 %), anteiso-C B/iso-C I (14.4 %) and C 7/iso-C 2-OH (13.8 %). The DNA G+C content of strain WPCB131 was 65 mol%. The isolate could be readily distinguished from other species using a combination of phenotypic characters. On the basis of the polyphasic evidence presented in this study, it is proposed that strain WPCB131 (=IMSNU 14116=KCTC 12533=NBRC 101118) represents a novel species, sp. nov.
