초록
In 2019, 43 bacterial strains were isolated from food, soil, marine environments, human, and animals related sources from the Republic of Korea. Based on the analysis of 16S rRNA gene sequence, these isolates were allocated to the phyla Bacteroidetes and Firmicutes as unrecorded species in Korea. The 10 Bacteroidetes strains were classified into the families Bacteroidaceae, Chitinophagaceae, Cytophagaceae, Flavobacteriaceae, and Prolixibacteraceae (of the orders Bacteroidales, Chitinophagales, Cytophagales, Flavobacteriales, and Marinilabiliales, respectively). The 33 Firmicutes strains belonged to the families Bacillaceae, Paenibacillaceae, Planococcaceae, Staphylococcaceae, Clostridiaceae, Lachnospiraceae, Peptostreptococcaceae, Enterococcaceae, Lactobacillaceae, Leuconostocaceae, and Streptococcaceae (of the orders Bacillales, Clostridiales, and Lactobacillales). These unrecorded bacteria were determined based on taxonomic criterion (>98.7%; 16S rRNA gene sequence similarity). In addition, their phylogenetic affiliation, as well as cell and colony morphologies, staining reactions, and physiological and biochemical properties were investigated. Therefore, we report 43 isolates as unrecorded species, and described basic features, isolation source, and locations of these strains.
Abstract
In 2019, 43 bacterial strains were isolated from food, soil, marine environments, human, and animals related sources from the Republic of Korea. Based on the analysis of 16S rRNA gene sequence, these isolates were allocated to the phyla Bacteroidetes and Firmicutes as unrecorded species in Korea. The 10 Bacteroidetes strains were classified into the families Bacteroidaceae, Chitinophagaceae, Cytophagaceae, Flavobacteriaceae, and Prolixibacteraceae (of the orders Bacteroidales, Chitinophagales, Cytophagales, Flavobacteriales, and Marinilabiliales, respectively). The 33 Firmicutes strains belonged to the families Bacillaceae, Paenibacillaceae, Planococcaceae, Staphylococcaceae, Clostridiaceae, Lachnospiraceae, Peptostreptococcaceae, Enterococcaceae, Lactobacillaceae, Leuconostocaceae, and Streptococcaceae (of the orders Bacillales, Clostridiales, and Lactobacillales). These unrecorded bacteria were determined based on taxonomic criterion (>98.7%; 16S rRNA gene sequence similarity). In addition, their phylogenetic affiliation, as well as cell and colony morphologies, staining reactions, and physiological and biochemical properties were investigated. Therefore, we report 43 isolates as unrecorded species, and described basic features, isolation source, and locations of these strains.
