  • 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.

  • In order to investigate indigenous prokaryotic species diversity in Korea, various environmental samples from diverse ecosystems were examined. 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 not reported in Korea, were selected as unrecorded species. 28 unrecorded bacterial species belonging to the phylum Bacteroidetes were discovered from various habitats including wastewater, freshwater, freshwater sediment, wet land, reclaimed land, plant root, bird feces, seawater, sea sand, tidal flat sediment, a scallop, marine algae, and seaweed. The unrecorded species were assigned to 18 different genera in five families: Flavobacterium, Epilithonimonas, Dokdonia, Gillisia, Flavicella, Chryseobacterium, Algibacter, Aquimarina, Lacinutrix, Gaetbulibacter, Cellulophaga, Tenacibaculum, and Maribacter of Flavobacteriaceae, Dyadobacter of Cytophagaceae, Draconibacterium of Draconibacterium_f, Sunxiuqinia of Prolixibacteraceae, and Fulvivirga of Fulvivirga_f. The selected isolates were subjected to further taxonomic characterization including analysis of Gram reaction, cellular and colonial morphology, biochemical activities, and phylogenetic trees. Descriptive information of the 28 unrecorded species is provided.

  • The phylum Actinobacteria includes many groups of aerobic, Gram-stain-positive, rod, or filamentous shaped bacteria. Actinobacteria are known for multicellular differentiation in some groups, and also for production of various secondary metabolites such as antibiotics. During a series of extensive surveys of indigenous prokaryotic species diversity in Korea, bacterial strains belonging to Actinobacteria were isolated from various sources of terrestrial environments. A total of 21 bacterial strains, belonging to 10 genera in 8 families, were isolated as unrecorded species in Korea. Among them, 11 were assigned to the family Streptomycetaceae, two species assigned to each of the families Microbacteriaceae, Mycobacteriaceae and Nocardioidaceae, and one species assigned to each of the families Euzebyaceae, Corynebacteriaceae, Micrococcaceae and Intrasporangiaceae. At the genus level, Streptomyces (10 species) was the most abundant, followed by Microbacterium and Mycolicibacterium(2 species each), and one species in each of the genera Corynebacterium, Euzebya, Arthrobacter, Terracoccus, Kribbella, Nocardioides and Yinghuangia. The detailed descriptions of each unrecorded species are provided.

  • As an outcome of the study on the bacterial species diversity in Korea, we report 24 unrecorded bacterial species of Korea belonging to the phylum Firmicutes. The unrecorded species excavated through this study were assigned to 12 different genera of 7 families, namely Bacillus, Halobacillus, Lysinibacillus and Thalassobacillus of Bacillaceae, Brevibacillus and Paenibacillus of Paenibacillaceae, Viridibacillus of Planococcaceae, Salinicoccus and Staphylococcus of Staphylococcaceae, Enterococcus of Enterococcaceae, Lactobacillus of Lactobacillaceae, and Lactococcus of Streptococcaceae, respectively. The bacterial isolates were obtained from various ecosystems in Korea. The isolates were identified based on 16S rRNA gene sequences, and those exhibiting at least 99% sequence similarity with known bacterial species but never reported in Korea were selected as unrecorded species. The selected isolates were subjected to further taxonomic characterization including the analysis of cell shape and fine structure using electron microscope, colony color and shapes, enzyme activities and carbon source utilization. The descriptive information on the 24 unrecorded species are provided.

  • In 2015 and 2017, the National Institute of Biological Resources has isolated four unrecorded prokaryotic species designated as R-1-5, R-2-13, R-2-1, and R-1-8 from the peatland soil of Yongneup. Phylogenetic analysis based on 16S rRNA gene sequence similarity determined the four strains (R-1-5, R-2-13, R-2-1, R-1-8) were most closely related to Curvibacter lanceolatus (99.93%), Massilia brevitalea (98.7%), Pseudomonas lini (99.54%), and Pseudomonas vancouverensis (99.93%), respectively. The four unrecorded strains belong to the phylum Proteobacteria, in which the genera Curvibacter and Massilia are assigned to the class Betaproteobacteria, and the genus Pseudomonas to the class Gammaproteobacteria. Since there are no publications or official reports on these four strains, these four species are new records to Korea. The strains were further characterized by Gram reaction, colony and cell morphology, basic biochemical properties, and phylogenetic position. Descriptive information of the four unrecorded species is provided.

  • In the course of our survey of microbial diversity, a total of seven basidiomycetous yeast strains were isolated from flowers sampled across the four provinces of the Republic of Korea, of which two strains were identified as an unrecorded species. Comparative analysis was conducted for identification of strains using the D1/D2 region of the large subunit(LSU) rRNA gene sequences, observation of cell morphologies, and carbon assimilation tests. Seven strains were classified within the phylum Basidiomycota. Two unrecorded strains, JRP1-10 (KACC 410703) and KC-1 (KACC 410704), were identified as Vishniacozyma pseudocarnescens, belonging to the family Bulleribasidiaceae, order Tremellales, class Tremellomycetes. Two strains had ellipsoidal-shaped and monopolar budding cells and smooth and cream-colored colonies after cultivation at 25℃ for 3 days. Here, we present the morphological and biochemical characteristics of the unrecorded yeast species, Vishniacozyma pseudocarnescens, in the Republic of Korea.
