Summary of "Flavobacterium aquariorum sp. nov., isolated from freshwater of the North Han River."

A non-motile, yellow-pigmented bacterial strain, designated IMCC34762, was isolated from a freshwater sample collected from Lake Cheongpyeong in Korea. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain IMCC-34762 formed a lineage within the genus Flavobacterium and was most closely related to F. pectinovorum DSM 6368 (98.3% sequence similarity), followed by F. piscis CCUG 60099 (98.3%), F. branchiicola 59B-3-09 (98.2%), and F. saccharophilum DSM 1811 (98.2%). The average nucleotide identity and the genome-to-genome distance between strain IMCC34762 and the closely related strains were 61-62% and 26-27%, respectively, indicating that IMCC34762 is a novel species of the genus Flavobacterium. The major fatty acids (> 5%) of strain IMCC34762 were summed feature 3 (Cω6c and/or Cω7c, 17.3%), iso-C (15.0%), iso-C G (9.0%), Cω6c (7.4%), iso-C (7.4%), and iso-C (5.3%). The major respiratory quinone and polyamine were MK-6 and sym-homospermidine, respectively. The major polar lipids were phosphatidylethanolamine, an unidentified aminophospholipid, and an unidentified lipid. The DNA G + C content of strain IMCC34762 was 34.4 mol%. Based on the taxonomic data presented in this study, strain IMCC-34762 represents a novel species within the genus Flavobacterium, for which the name Flavobacterium aquariorum, sp. nov. is proposed. The type strain is IMCC34762 (= KACC 19725 = NBRC 113425).
