To investigate the indigenous prokaryotic species diversity in Korea, various environmental samples from diverse ecosystems were examined taxonomically. The isolated bacterial strains were identified based on 16S rRNA gene sequences, and those exhibiting at least 98.7% sequence similarity with known bacterial species but never reported in Korea were selected as unrecorded species. As an outcome of this study, 10 unrecorded bacterial species belonging to the phylum Firmicutes were discovered from various sources such as soil, tidal flat, fresh water, sea water, kimchi and gut of Fulvia mutica. The unrecorded species were assigned to 7 different genera of 5 families, namely Bacillus and Ornithinibacillus of Bacillaceae, Exiguobacterium of Exiguobacteriaceae, Brevibacillus and Paenibacillus of Paenibacillaceae, Staphylococcus of Staphylococcaceae, and Lactococcus of Streptococcaceae. The selected isolates were subjected to further taxonomic characterization including the analysis of Gram reaction, cellular and colonial morphology, biochemical activities, and phylogenetic trees. The descriptive information on the 10 unrecorded species are provided.
