Abstract

As part of a comprehensive investigation of indigenous prokaryotic species in Republic of Korea in 2022, 156 bacterial strains were isolated from diverse environmental habitats. These strains were assigned to six phyla, namely Acidobacteriota, Deinococcota, Actinomycetota, Bacillota, Bacteroidota, and Pseudomonadota. Each strain was identified based on 16S rRNA gene sequence similarity (>98.7%) and the formation of robust phylogenetic clades with their closest reported species. Among isolates, there is one species belonging to the phylum Acidobacteriota, one species belonging to the phylum Deinococcota, 28 species belonging to the phylum Actinomycetota, 19 species belonging to the phylum Bacillota, 19 species belonging to the phylum Bacteroidota, and 88 species belonging to the phylum Pseudomonadota (comprising 34 species of the class Alphaproteobacteria, 20 species of the class Betaproteobacteria, and 34 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 156 isolates in Republic of Korea, they are reported as unrecorded species in Republic of Korea. The Gram stain, colony and cell morphology, basic biochemical characteristic, isolation source, and strain ID of each species are described in the species descriptions.
