Abstract
Within a comprehensive, widescale investigation of indigenous prokaryotic species in Korea, 29 bacterial strains in the phylum Bacteroidetes were isolated from diverse environmental habitats that included soil, plant roots, natural caves, tidal flats, freshwater from lakes, and seawater. Based on their high 16S rRNA gene sequence similarities (>99.1%) and the formation of robust phylogenetic clades with the closest type species, each strain likely belonged to an independent and predefined bacterial species. There are no publications or official reports of the isolation of these 29 species in Korea. Our study provides strong evidence that seven species in three genera in the order Cytophagales, 15 species in 13 genera in the order Flavobacteriales and seven species in five genera in the order Sphingobacteriales, all within the phylum Bacteriodetes, are new reports of bacterial species in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are described in the species description section.
