In an investigation of indigenous prokaryotic species in Korea, a total of 35 bacterial strains assigned to the phylum Firmicutes were isolated from diverse habitats including natural and artificial environments. Based on their high 16S rRNA gene sequence similarity (>98.7%) and formation of robust phylogenetic clades with species of validly published names, the isolates were identified as 35 species belonging to the orders Bacillales (the family Bacillaceae, Paenibacillaceae, Planococcaceae, and Staphylococcaceae) and Lactobacillales (Aerococcaceae, Enterococcaceae, Lactobacillaceae, Leuconostocaceae, and Streptococcaceae). Since these 35 species in Korean environments has not been reported in any official report, we identified them as unrecorded bacterial species and investigated them taxonomically. The newly found unrecorded species belong to 20 species in the order Bacillales and 15 species in the order Lactobacillales. The morphological, cultural, physiological, and biochemical properties of the isolates were examined and the descriptive information of the 35 previously unrecorded species is provided here.
