Abstract

As part of a comprehensive investigation of indigenous prokaryotic species in the Republic of Korea, 37 bacterial strains belonging to 36 species were isolated from diverse environmental habitats. These strains were assigned to five phyla, namely Deinococcota, Actinomycetota, Bacillota, Bacteroidota, and Pseudomonadota. Each strain was identified based on 16S rRNA gene sequence similarity (>98.7%) and the formation of definite phylogenetic clades with their closest reported species. Among isolates, there is one species belonging to the phylum Deinococcota, five species belonging to the phylum Actinomycetota, four species belonging to the phylum Bacillota, nine species belonging to the phylum Bacteroidota, and 17 species belonging to the phylum Pseudomonadota (comprising eight species of the class Alphaproteobacteria, one species of the class Betaproteobacteria, and eight species of the class Gammaproteobacteria). Based on 16S rRNA gene sequence analysis, each strain was assigned to independent and predefined bacterial species. Since there were no published or official reports regarding these 36 species in the Republic of Korea, they have been reported as unrecorded species in the Republic of Korea. Their Gram stain, cell morphology, colony, basic biochemical characteristics, strain ID, and isolation source of each species are described in the species descriptions.
