  • During a field survey on Korean coastal marine waters, two ciliates belonging to the genera Pseudovorticella Foissner & Schiffmann, 1975 and Frontonia Ehrenberg, 1838 in the class Oligohymenophorea de Puytorac et al., 1974, were collected. Even though the two genera are very common in the aquatic ecosystems, they had been superficially studied in Korean habitats. Using the observation of living cells and specimens impregnated by protargol, silver carbonate, and silver nitrate, two newly recorded ciliate are identified as P. paramarina Sun, Ji, Warren & Song, 2009 and F. ocularis Bullington, 1939. A brief diagnosis, remark, and comprehensive micrographs are provided for each species.

  • The diversity elucidation by amplified ribosomal DNA restriction analysis and 16S rDNA sequencing of 96 associative diazotrophs, isolated from the feeder roots of tea on enriched nitrogen-free semisolid media, revealed the predominance of Gram-positive over Gram-negative bacteria within the Kangra valley in Himachal Pradesh, India. The Gram-positive bacteria observed belong to two taxonomic groupings; Firmicutes, including the genera Bacillus and Paenibacillus; and Actinobacteria, represented by the genus Microbacterium. The Gram-negative bacteria included ${\alpha}$-Proteobacteria genera Brevundimonas, Rhizobium, and Mesorhizobium; ${\gamma}$-Proteobacteria genera Pseudomonas and Stenotrophomonas; and ${\beta}$-Proteobacteria genera Azospira, Burkholderia, Delftia, Herbaspirillum and Ralstonia. The low level of similarity of two isolates, with the type strains Paenibacillus xinjiangensis and Mesorhizobium albiziae, suggests the possibility of raising species novum. The bacterial strains of different phylogenetic groups exhibited distinct carbon-source utilization patterns and fatty acid methyl ester profiles. The strains differed in their nitrogenase activities with relatively high activity seen in the Gramnegative strains exhibiting the highest similarity to Azospira oryzae, Delftia lacustris and Herbaspirillum huttiense.

(2) There were 144 taxa (125 species, 15 varieties and 4 forms of 91 genera of 49 families) for the woody plants, while 215 taxa(181 species and 34 varieties of 157 genera of 54 families) were identified for the herbaceous plants. Twenty-nine taxa (28 species and 1 variety of 22 genera of 12 families) were investigated for the naturalized plants at the study sites. (3) Currently existing dominant vegetation forming the major trees layer at the study sites were Robinia pseudoacacia, Chamaecyparis pisifera, C. obutusa, Torreya nucifera, Castanea crenata and Acer buergerianum for the planted species, and naturally growing species forming the major trees layer were Quercus acutissima and Q- serrata.

  • The flora of the Odaesan National Park, located in the areas of Pyongchang-gun, Myongju-gun and Inje-gun, Kangwon-do was surveyed. Field works was undertaken five times between March to October, 1995. The total number of vascular plants in the Odaesan National Park was surveyed was 512 taxa; 87 families, 277 genera, 435 species, 68 varieties, 2 subspecies, and 7 forms. The vascular plants were classified as 459 taxa, 85 families, 255 genera, 389 species, 61 varieties, 2 subspecies and 7 forms in Odaesan, 309 taxa 73 families, 194 genera, 257 species, 45varieties, and 5 forms in Hwangbyongsan and 151 taxa, 60 families, 115 genera, 138 species, 12 varieties and 1 form in Sogumgang area. Also this study recorded 35 taxa of Korean rare and endangered plant species. Some of the habitats of rare and endangered plant species are located in the vicinity from the nature trails. Conservation measures, at both the habitat and species levels, are urgently needed to mitigate against destructive human activities, such as an illegal mass collecting and trampling.

  • Objectives: This study aims to provide basic data regarding the bacterial total plate count in the atmospheric environment for related studies. Methods: Total plate count and the identification of culturable bacteria in the atmospheric environment in Incheon took place in 2015 using periodic survey. Correlationship analysis was performed between the number of culturable bacteria and environmental elements. In addition, an estimation of novel bacterial species was undertaken using the similarities and phylogenetic tree based on the 16S rRNA gene. Results: The total plate count of culturable bacteria was on average $176CFU/m^3$, and did not exceed $610CFU/m^3$ in the atmospheric environment. Periodic monthly measuring of total plate count was highest in June at $293CFU/m^3$, while the lowest was in July at $125CFU/m^3$. Furthermore, as a result of the identification of culturable bacteria, the genera Arthrobacter and Kocuria were dominant, while novel bacterial taxa that belong to the genera Chryseobacterium and Herbiconiux were separated. Conclusion: The total number of culturable bacteria from the atmospheric environment in Korea is on average $176CFU/m^3$. In addition, the genera Arthrobacter and Kocuria dominate. The presence of novel bacterial taxa are expected in the atmospheric environment, such as belonging to the genera Chryseobacterium and Herbiconiux.

  • Enzyme linked-immunosorbent assay (ELISA) for a rapid detection of fungi, Aspergillus and Penicillium genera in food, were developed and their efficiencies were approved by detecting artificially contaminated agricultural commodities. Mice were immunized with partially purified Aspergillus flavus extracellualr polysaccharide (EPS) and lymph node cells of the mice were fused with the myeloma cells for production of monoclonal antibodies. Mab 1G11, one of the antibodies, was selected and purified. A sandwich ELISA was established and its detection limit toward A. flavus EPS was 1mg/ml. Among the 59 strains tested (including 18 species of Aspergillus, 16 of Penicillium, 11 of Fusarium, 1 of Absidia, 2 of Alternaria, 2 of Candida, 2 of Cladosporium, 2 of Geotrichum, 2 of Mucor, 2 of Rhizopus, 1 of Trichoderma), species of Aspergillus and penicillium had a high reactivity with Mab 1G11 even up to 10,000 times dilution of culture broths. The other genera except Cladosporium resinae showed no reactivity, thus Mab 1G11 was specific to the genera of Aspergillus and Penicillium. The epitope of A. flavus EPS against monoclonal Mab 1G11 was on the carbohydrate moiety when 1 to 100$\mu g/g$ A. flavus EPS were put into rice, potato, and mandarin orange, the average recoveries detected by sandwich ELIA were 123, 59, and 76%, respectively. Correlation was found to be linear between the EPS, and mycelium of A. flavus and Penicillium citrinum grown in a liquid medium (r=0.87 and 0.96), and also between the EPS and colony forming unit in solid media of rice of potato (r=0.91-0.99).
