  • In this study, the anaerobic enrichment cultivation was performed with the sediments and the dredged soils from the cities of Ulsan, Masan, Yeosu, Gwangyang, Ansan and Seongnam. Acetate as an electron donor and PCE (perchloroethylene) or TCE (trichloroethylene) as an electron acceptor were injected into the serum bottle with an anaerobic medium. After the incubation of 12 weeks, the removal efficiency of PCE was highest at $70\%$ in the treatment with the sediment of Ulsan. Also, the bacterial community structure was analyzed by D-DGGE (double denatured gradient gel electrophoresis) through PCR-based 16S rDNA approaches. The dominant species id the anaerobic enrichment were found to belong to the genus of Desulfovibrio.

  • Despite the huge worldwide diversity of Trichoderma (Hypocreaceae, Ascomycota), only about 22 species have been reported in Korea. Thus, between 2013 and 2015, soil-derived Trichoderma spp. were isolated to reveal the diversity of Korean Trichoderma. Phylogenetic analysis of translation elongation factor 1 alpha gene was used for identification. Among the soil-derived Trichoderma, Trichoderma albolutescens, T. asperelloides, T. orientale, T. spirale, and T. tomentosum have not been previously reported in Korea. Thus, we report the five Trichoderma species as new in Korea with morphological descriptions and images.
