  • The authors attempted utilization of fatty acid composition of vibrios as a tool for identification of the strains. Fatty acid of 49 strains of Vibrio cholerae non-O1, V. cholerae O1, V mimicus, V vulinificus and V parahaemolyticus was analyzed by gas-liquid chromatography column. According to the statistical analysis of the fatty acid data, the relationship between the Vibrio species and serotypes of the strains was discussed. Forty one kinds of fatty acid were detected from the tested strains and 35 kinds of fatty acids among the detected fatty acids were significant factors to identify the vibrios. The predominant fatty acids were 16:0, 16:1 cis 9, 18:1 trans 9/6/cis 11 and 15:0 iso 2OH/16:1 cis 9 as above about 20% in total. Fatty acid compositions of the Vibrio species were an important factor in identifying their subspecies either predominant fatty acids or minor ones. According to the analysed results by a conventional statistical processing method (UPGMA) and prepared dendrogram, V cholerae non-01 had more closer relationship with V. mimicus compared with V. cholerae 01. Moreover, the distribution of hydroxy acid was a significant factor for identifying V cholerae subspecies. Comprising all the 10 serotypes detected from V. cholerae non-01 examined such as O2, O5, O8, O10, O14, O27, O37, O39, O45 and O69, we could group them into seven subspecies by cluster analysis with the similarity value of fatty acid composition as above 92%. It means that there is a significant relationship between serotypes and fatty acid composition of V. cholerae. These results indicated that numerical analysis of fatty acid composition data of V cholerae non-01 could classifY them into subspecies, and also which may provide a useful epidemiologic information or a basis for further analysis such as PCR and DNA probe analysis.

  • This study was conducted to investigate the distribution of vascular plants in five islands of Jisimdo, Naedo, Yoondoldo, Songdo and Galdo in East Hallyeohaesang National Park. The Islands were surveyed from 2010 to 2011. The flora was classified to as: Jisimdo, 246 taxa; 85 families, 195 genus, 219 species, 3 subspecies, 24 varieties and 2 forma. Naedo, 143 taxa; 72 families, 127 genus, 131 species, 12 varieties. Yoondoldo, 84 taxa; 56 families, 73 genus, 219 species, 1 subspecies, 10 varieties. Songdo, 70 taxa; 33 families, 63 genus, 64 species, 6 varieties and Galdo, 93 taxa; 47 families, 84 genus, 84 species, 1 subspecies, 7 varieties, and 1 forma. Thus, a total of 380 taxa; 105 families, 272 genus, 334 species, 3 subspecies, 39 varieties and 4 forma were observed. A total of 8 and 6 taxa were found to be rare plants in surveyed areas and endemic to Korea, respectively. Distribution of floristic special plants in the surveyed area was divided into five classes (class I-V), 42 taxa; were in class I, 1 taxa; was in class II, 25 taxa; were in class III, 4 taxa; were in class IV and 4 taxa; were in class V. Total floristic special plants were 76 taxa.

  • Three species of Archaeogastropoda were found new to the fauna of Korea, and are described in this paper. These include Emarginulo crossicostato Sowerby, 1863, Collisello cassis (Eschscholtz, 18331, and Collonista umakusaensis Habe, 1950. As the result, the Korean marine Archaeogastropod fauna comprises 10 families, 67 species and 9 subspecies.
