  • This study was carried out to investigate the flora of Mt. Suan (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 402 taxa in total were identified, including 102 families, 274 genera, 354 species, 6 subspecies, 40 varieties and 2 forms. Among them, 8 taxa of Korean endemic plants and the Korea Forest Service-designated rare plants were identified as 5 taxa. Based on the list of plants which have been approved for overseas delivery, 10 taxa were recorded in the investigated area. The Ministry of Environment-designated specially plants were identified as 17 taxa. The naturalized plants were identified as 41 taxa and the percent of naturalized index (NI) was 10.2% of total 402 taxa vascular plants.

  • This study was performed to investigate the flora and plant resources of Mt. Gamak (537.8 m) from April to October 2007. The collected vascular plants were composed of all 478 taxa including cultivated species, and classified into 410 species, 3 subspecies, 61 varieties, and 4 forms of 284 genera under 94 families. Six taxa of the Korean endemic plants and 4 taxa of the rare and endangered plants were also distributed in this mount. Resource plants were categorized into edible 222, pasturing 208, medicinal 183, stainable 134, ornamental 96, timber 20, fiber 6 and industrial 4 taxa, respectively. Floristic geography of the investigated area was regarded as the boundary between middle parts in floristic pattern of the Korean Peninsula.

  • In recent years, the knowledge about bifidobacteria has considerably evolved thanks to recent progress in molecular biology. The analysis of the whole genome sequences of 48 taxa of bifidobacteria offers new perspectives for their classification, especially to set up limit between two species. Indeed, several species are presenting a high homology and should be reclassified. On the other hand, some subspecies are presenting a low homology and should therefore be reclassified into different species. In addition, a better knowledge of the genome of bifidobacteria allows a better understanding of the mechanisms involved in complex carbohydrate metabolism. The genome of some species of bifidobacteria from human but also from animal origin demonstrates high presence in genes involved in the metabolism of complex oligosaccharides. Those species should be further tested to confirm their potential to metabolize complex oligosaccharides in vitro and in vivo.

  • The systematic study of recent freshwater ostracods were conducted on the materials collected from 48 localities in South Korea. Four species of ostracods are identified, and all of them are new to South Korea : Cyprinotus uenoi Brehm , 1936, Heterocypris incongruens (Ramdohr, 1808), Dolerocypris fasciata(O.F.Mller, 1776 ), Dolerocypris sinensis Sars, 1903. Up to now seven species (5 species and 2 subspecies ) of recent ostracods are known to South Korea.

  • Five species of Tomoceridae from Korean caves are reviewed , including one speices described as new to science. T. (M.) odongnyeoensis n.sp. belong to the subgenus of new record for Korea. The present study eventually resulted in listing eight species in five subgenera of Korea cave Tomoceridae, and all Collebola from Korean caves nowenumerate 23 species (or subspecies) in nine genera of eight families.

  • The degree of the genetic variations among Clostridium thermocellum ATCC 27405 and the wild type strains was investigated by the mehtod of GC ratio, DNA-DNA hybridization and RFLP (Restriction Fragment Length Polymorphism) patterns by ribosomal RNA and M13 probe. GC ratio and KNA homology values of th three isolates were approximately equal to those of ATCC type strain. The RFLP patterns by the rRNA and M13 probe showed some differences among C. thermocellum ATCC 27405, wild type strains and Clostridium thermohydrosulfuricum ATCC 33223, indicating that the two probes can be useful in subspecies- and apecies-identification.

  • Global Biodiversity is common interest of humans for better health and sustainable development of the society. To provide access and analysis on microbial diversity information, Bacteriology Insight Orienting System (BIOS) has been developed. BIOS contains 6402 species and subspecies names of bacteria and archaea, 2606 names of cyanobacteria by March 2000. BIOS of which web based analytical tool provides windows to compare the results of phylogenetic analysis based on 16S rDNA sequence and the results of cluster analysis on proteome profiling. The sequence data and 2 dimensional gel electrophoresis analysis data were accumulated in BIOS database content for cyanobacteria reclassification and taxonomy.

  • Mt. Jabyeong(872.5m), limestone region in the Taebaek mountains, located in 37° 32'N, 129° 25'E and in Sangye-ri, Okgye-myeon, Gangreung-si and Samok-ri, Imgye-myeon, Jeongseon-gun, Gangwon-do. The purposes of this study were to investigate the floristic composition from 1997 to 1998 in Mt. Jabyeong and report the distribution of Korean endemic plants, rare and vulnerable plants, calcicoles and calci fuges, The vascular plants in this area were composed of 93 families, 313 genera, 3 subspecies, 57 varieties, 13 forms, 495 species, totaling 568 taxa. Among the vascular plants, 21 taxa were Korean endemic plants and 7 taxa were rare and vulnerable plants. Calcicole and calcifuge plants in this study area were composed of 21 families, 30 genera, 36 species and 14 families, 15 genera, 17 species. The soil pH values of study site in Mt. chabyoung were ranging 7.4∼8, which showed that this site was a mostly limestone area with alkaline soil. And soil depth was formed to a relative thin layer, mostly 2~4cm thickness. This site showed high content of moisture and organic matter which were ranging 40-45% and 15-25%, respectively.
