Flavobacterium chungangense sp. nov., isolated from a freshwater lake

Chung-Ang University

¹ E-mail: cjcha{at}cau.ac.kr

A yellow-pigmented, rod-shaped Gram-staining-negative, aerobic bacterial strain designated CJ7^T, was isolated from a freshwater lake of 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 Flavobacterium. Strain CJ7^T showed sequence similarity values of 91.47-97.99% to the type strains of recognized Flavobacterium species. The DNA-DNA relatedness between strain CJ7^T and F. hercynium DSM 18292^T, which showed the highest 16S rRNA gene sequence similarity, was 25.4%. The predominant cellular fatty acids were iso-C15 : 0 (18.3%), summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 17c) (16.1%), iso-C17 : 0 3-OH (8.9%), iso-C15 : 0 3-OH (7.2%), iso-C17 : 19c (6.1%) and iso-C15 : 1 (5.9%). Flexirubin-type pigments were absent. The major isoprenoid quinone was menaquinone-6. The DNA G+C content was 34.5 mol%. Results from the polyphasic taxonomy study suggested that strain CJ7^T represents a novel species of the genus Flavobacterium for which the name Flavobacterium chungangense sp. nov. is proposed. The type strain is CJ7^T (= KACC 13353^T = JCM 15651^T).
