초록
During a comprehensive investigation of indigenous prokaryotic species in Korea, a total of 31 bacterial strains assigned to the phylum Actinomycetota were isolated from diverse environmental habitats, including soil, mud, wetland, tidal field, and seawater. Based on their high 16S rRNA gene sequence similarities(>98.7%) and the formation of robust phylogenetic clades with the closest type species, each strain was assigned to an independent and predefined bacterial species. Because there have been no publications or official reports regarding 31 isolates in Korea, these 31 species of 12 families within seven orders of the phylum Actinomycetota are reported as unrecorded species in Korea. In addition, Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs are also described in the species description section.
