초록

As a part of the research project "Survey of freshwater organisms and specimen collection," freshwater samples were collected from the Nakdong River. Among the bacterial isolates, we selected strains that showed higher than 98.7% 16S rRNA gene sequence similarity with confirmed bacterial species previously unreported in South Korea. The 14 new records to South Korea were phylogenetically diverse and belonged to four phyla, six classes, 11 orders, and 14 genera. At the genus level, these species were found to be affiliated with Reyranella, Ferrovibrio, Brevundimonas, and Aquidulcibacter of the class Alphaproteobacteria; Pseudomonas, Cellvibrio, and Photobacterium of the class Gammaproteobacteria; Paenibacillus and Bacillus of the phylum Firmicutes; Chryseobacterium, Flavobacterium, Pedobacter of the phylum Bacteroidetes; and Actinomadura and Leifsonia of the phylum Actinobacteria. These species were further characterized by examining their Gram reaction, colony and cell morphologies, biochemical properties, and phylogenetic positions. The detailed descriptions of these 14 previously unreported species are provided.
