Abstract

A yellow-pigmented, rod-shaped, Gram-staining-negative, aerobic bacterial strain, designated CJ7, was isolated from a freshwater lake at Chung-Ang University in Anseong, South Korea. Results from 16S rRNA gene sequence analysis revealed that the isolate was phylogenetically affiliated with members of the genus . Strain CJ7 showed sequence similarity values of 91.5–98.0 % to the type strains of recognized species. The DNA–DNA relatedness between strain CJ7 and DSM 18292, which showed the highest 16S rRNA gene sequence similarity, was 25.4 %. The predominant cellular fatty acids were iso-C (18.3 %), summed feature 3 (comprising iso-C 2-OH and/or C 7) (16.1 %), iso-C 3-OH (8.9 %), iso-C 3-OH (7.2 %), iso-C 9 (6.1 %) and iso-C (5.9 %). Flexirubin-type pigments were absent. The major isoprenoid quinone was menaquinone-6. The DNA G+C content was 34.5 mol%. The results obtained from this study, with a polyphasic taxonomic approach, suggested that strain CJ7 represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is CJ7 (=KACC 13353=JCM 15651).
