  • Ethanol treatment method was attempted for the selective isolation of ethanol-tolerant fungi from two sites of rice paddy fields around Seoul area. The vertical and seasonal fluctuation of the fungal population were also investigated. The ethanol-tolerant fungi were Talaromyces stipitatus, T. flavus var. flavus, T. helicus var. major, Eupenicillium javanicum, Emericellopsis terricolor, Pseudourotium zonatum, Aspergillus flavus, Cladosporium cladosporioides, Penicillium frequentans, P. janthinellum, and P. verruculosum. The most dominant species isolated by this method was T. stipitatus. It was found that the numbers of fungal species and colony forming units(CFUs) of ethanol-tolerant fungi were higher in Ascomycota than in Deuteromycota. A particular tendency appeared the highest CFUs in autumn, but lower in spring and winter. T. stipitatus was the dominant species of ethanol tolerant microfungi. This result would suggest that membrane lipid composition of ethanol-tolerant fungi isolated from the soils may play on important role in the ethanol tolerance.

  • Ectomycorrhizal fungi are associated with plants roots and acquire significant amounts of nitrogen sources from the soil. For artificial cultivation, mass production of ectomycorrhizal fungi in liquid media is required. We studied the edible ectomycorrhizal mushrooms Hygrophorus russula, Ramaria fumigata, Sarcodon aspratus, and Tricholoma matsutake. All strains except S. aspratus NIFoS 2031 grew generally well on modified Melin-Norkran's (MMN) medium compared to on other media. All strains analyzed in this study showed significantly higher growth on organic nitrogen. Specifically, two strains of H. russula significantly responded to both tryptone and neopeptone media. Among different species and strains, there were clear differences in the capacity to grow on animal-based organic nitrogen sources.

  • The silverleaf whitefly, Bemisia tabaci, is a major pest distributing worldwide damaging over 900 host plant species, and is highly resistant to chemical pesti- cides. Due to the high pesticide resistance of whitefly, there is a need for alternatives to chemical control. Entomopathogenic fungi are candidates for biological pesticide that can overcome the resistance problem of chemical pesticide. Therefore, in this study, we tested pathogenicity of the entomopathogenic fungi to select high insec- ticidal activity against whitefly. As a result, IPBL-C (Cordyceps fumosorosea) and IPBL-F (Metarhizium pinghaense) isolates showed high insecticidal activity against whitefly. Additionally, as a result of culturing the selected isolates on spent coffee grounds medium, the conidia of IPBL-F produced on coffee grounds medium showed five times higher heat stability after heat treatment at 45℃ for one hour than conidia produced on PDA medium.

  • 국내에서 재래적인 방법에 의하여, 생산 시판되고 있는 전통 발효식품인 메주(12종), 된장(28종) 및 간장(28종)을 수거하여 이들로부터 OA를 생성하는 fungi를 분리 및 동정하였고, 동정된 fungi 중 OA를 가장 많이 생성하는 4 isolates을 선택하여 이들의 생육과 OA 생성 특성을 조사하였다. 각 시료에서 불리해낸 222 fungi 중 OA를 생성하는 것은 39 isolates로, 곰팡이의 OA 생성률이 17.7%(39/222)이며, 이들 중 가장 많은 OA를 생성하는 4 Fungi는 Penicillium spp., Phialotubus microsporus, Eupenicillium lapidosum 및 Paecilomyces variotti이었다. 이들 균주는 $a_{w}$ 0.99에서 가장 잘 자랐고 $a_{w}$ 0.85에서 OA의 생성이 중지되었다. 또한 $30^{\circ}C$에서 억제되었다. Toxin 생성 최적 pH는 Paecilomyces variotti을 제외하고는 6.5이었으며 pH에 의해서 toxin 생성은 $a_{w}$와 달리 영향을 크게 받지 않았다.

  • The seed-borne mycoflora of sorghum and foxtail millet collected from different growing areas in South Korea were isolated and taxonomically identified using dry inspection, standard blotter and the agar plate method. We investigated the in vitro and in vitro germination rates of disinfected and non-disinfected seeds of sorghum and foxtail millet using sterilized and unsterilized soil. The percent recovery of seed-borne mycoflora from the seed components of sorghum and foxtail millet seeds was determined and an infection experiment using the dominant species was evaluated for seedling emergence and mortality. A higher number of seed-borne fungi was observed in sorghum compared to that of foxtail millet. Eighteen fungal genera with 34 fungal species were identified from the seeds of sorghum and 13 genera with 22 species were identified from the seeds of foxtail millet. Five dominant species such as Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme and Phoma sp. were recorded as seed-borne mycoflora in sorghum and 4 dominant species (Alternaria alternata, Aspergillus flavus, Curvularia lunata, Fusarium moniliforme) were observed in foxtail millet. The in vitro and in vitro germination rates were higher using disinfected seeds and sterilized soil. More seed-borne fungi were recovered from the pericarp compared to the endosperm and seed embryo. The percent recovery of seed-borne fungi ranged from 2.22% to 60.0%, and Alternaria alternata, Curvularia lunata and 4 species of Fusarium were isolated from the endosperm and embryo of sorghum and foxtail millet. Inoculation of the dominant seed-borne fungi showed considerable mortality of seedlings. All the transmitted seed-borne fungi might well be a primary source of infection of sorghum and foxtail millet crops.
