Studies on the Pathogenicity of Aphelenchoides sp. and Rhabditis sp. attacking Cultivated Mushroom, Agaricus bisporus(Lange) Sing

Four species of nematodes attacking mushroom beds were found in samples taken from 35 mushroom farms throughout Korea. These were Rhabditis sp., Aphelenchoides sp., Ditylenchus sp. and Aphelenchus sp. ,Rhabditis sp. was found from compost and casing from all mushroom farms and the frequencies of Aphelenchoides sp. was 31.4% in the both compost and casing. Both Ditylenchus sp. and Aphelenchus sp. showed 2.7% of frequencies in the compost, none in casing. Temperature and moisture content of compost affected pathogenicity of Aphelenchoides sp. on mushroom mycelia grown in compost. The higher temperature and moisture content the sooner the damage became apparent, and the more rapid was subsequent destruction of mycelia. There was no mycelial destruction at the lowest temperature of
. Rhabditis sp. completely disintegrated mycelia grown in the compost, in the early stage, the numbers of Rhabditis sp. rose gradually and then increased suddenly to reach a peak but soon declined. At first, the pH of Rhabditis-infested spawned compost declined but then rose gradually as mycelia was disintegrated by nematodes. The trend in pH of infested unspawned compost was similar to those of uninfested, unspawned compost. Cultures inoculated with surface-disinfected dead Rhabditis sp. and with tap water used in the nematode extraction procedures showed no mycelial injury associated microorganisms containing within or outside the nematodes even though added by artificial wounding of the mycelia. Cultures artificially wounded showed no injury away from the wounds without the presence of living Rhabditis sp., such wounded mycelia slowly regenerated. On the other hand, artificial wounding accelerated the breakdown of mycelia in the presence of living Rhabditis sp.
Taxonomic Investigations on Korean Higher Fungi(II) -Two Unrecorded Species of the Genus Cordyceps in Korea-

The Korean Journal of Mycology, volume 1, issue 1, 1973, Pages 13~16
Two species of the family Clavicipitaceae, Cordyceps tricentri Yasuda and Cordyceps sphecocephala (Klotz) Mass. which have not been reported so far in Korea, were collected and identified. These are added to the list of three previously recorded species, Cordyceps sobolifera, C, militaris, and C. nutans.
Studies on the Population of Toxigenic Fungi in Foodstuffs -IV. Screening test for strains that produce aflatoxin like substances-

The Korean Journal of Mycology, volume 1, issue 1, 1973, Pages 17~21
Fifty-eight strains of Aspergillus spp. isolated from various grains were examined for the screening of aflatoxins by the method of the Thin-Layer Chromatography (TLC), using the aflatoxin producing strain of Aspergillus flavus ATCC 15517 as a control. The results as follows: 1. Samples of Aspergillus spp. isolated from various grains were extracted with chloroform and chromatographied by the thin-layer chromatography method. 2. Three strains of Aspergillus spp. among the 58 strains can be found that the spots having the same Rf value as control with culture extract of Aspergillus flavus ATCC 15517. 3. The further prove studies of aflatoxins were proceed by the methods of in vivo and in vitro tests. And this methods considered to capable for the use of mass screening among the samples.
Studies on the Cellulase of Penicillium sp. Isolated from Soils. -(1) Isolation of Penicillium sp. C8-14 strain from Kwangneung soil-

The Korean Journal of Mycology, volume 1, issue 1, 1973, Pages 23~28
The soil of Kwangneung area(Kyeunggi-Do) was inoculated directly into wheat-bran-media and after
days of incubation, a Penicillium species whose cellulase activity was 1011u/g was isolated. With the treatment of mutagenic agents an improved strain(cellulase activity: 1303u/g) was obtained. This strain was screened again by mono-spore isolation method. Finally a strain C8-14 (cellulase activity: 2351u/g) which had lesser spores than the wild strain was obtained.
Studies on the Antifungal Activities of Siccanin and Azalomycin-F in vitro Tests

The discovery of ideal therapeutics of fungal infections are remain a major problems of several mycoses. The antifungal activities of a new antifungal antibiotic named Siccanin and Azalomycin-F studies in vitro against some various species of fungi especially dermatophytes. The antifungal activity tests were performed according to the tube-dilution method and all subcultures were incubated at room temperature for 14 days. Results were obtained as follows: 1. All of the Candida spp. were grow on the various concentration of Siccanin tested but Azalomycin-F were growth inhibited at 7mcg-10mcg per ml. 2. Trichophyton spp. and Microsporum spp. were inhibited for growth at 2mcg-6mcg per ml. and 3mcg-5mcg per ml. concentration of Siccanin and 1mcg-4mcg per ml. of Azalomycin-F. 3. Deep mycoses and some saprophytes were grow on the all tested concentration of Siccania and Azalomycin-F.
