Notes on genus Entoloma of Korea (II)
Cho, Duck-Hyun ; Park, Seong-Sick ;
The Korean Journal of Mycology, volume 19, issue 2, 1991, Pages 93~100
Eight species of genus Entoloma were collected from the areas around Mt. Manduck and newly identified in Korea; Entoloma scabrosum, E. aethiops var. aethiops, E. pallid-olivaceum, E. sericellum, E. sarcitum, E. anatinum, E. tortuosum, and E. mephiticum. Detail descriptions and Korean descriptions for them were made.

To classify fungal species employed for pharmacological effects, mycelial proteins of six isolates of Ganoderma lucidum, five isolates of Schizophyllum commune and five isolates of Cordyceps spp. were separated on polyacrylamide gel to compare them by esterase, acid phosphatase, leucine aminopeptidase and peroxidase patterns. Similarity of isozyme patterns among the isolates of G. lucidum IY003, IY004, IY005 and IY008 was indicated over 70%, but that among the isolates of G. lucidum IY009, IY010 and others was indicated from 48% to 9%. Highest similarity of isozymes of S. commune was observed to be between IY803 and IY805, and similarity between these two isolates was 57%. Similarity among other isolates was shown to be from 40% to 56%. Isozyme patterns of Cordyceps spp. were comparatively different, even though they were originated from the same kind of insect as their isolate. Similarity between Cordyceps spp. IY901 and IY904, which was isolated from moths, was 67% and that of IY905 and IY909, which was originated from the larvae, was 42%. Similarity among other isolates was shown to be from 12% to 67%.

The vertical distribution of the fungal population for the soil samples from two sites of producing and nonproducing of Tricholoma matsutake, song-yi mushroom, were examined at Yangyang and Myung-joo, Gangweon province. By the dilution plate method, a total number of propagules of fungi per gram of soil was observed to be low at the song-yi producing sites but high at the song-yi nonproducing sites under the communities of Pinus densiflora. The tendency of the number of fungal propagules were decreased with the increasing vertical depth. In the incuhation method at
, six genera and nineteen species of the fungi were isolated from two sites; Aspergillus fumigatus, Acremonium sp., Talaromyces stipitatus, Penicillium lilacinum, P. oxalicum and Westerdykella multispora. The most dominant species by this method was A. fumigatus. From heat treatment method at
, seven genera and nineteen species were isolated; Aspergillus fumigatus, Alternaria alternata, Neurospora sitophila and Mucor sp.. In the ethanol treatment method, one genera and one species was isolated Mortierella sp.. From the three isolation methods, it was found that the total number of the soil fungi and the frequency of species appeared were the highest at the soil of upper layer whereas the lowest at the soils of lower layer in its vertical distribution.

The Korean Journal of Mycology, volume 19, issue 2, 1991, Pages 120~127
Several isolates producing the red-pigment were isolated from the Korean and Brazilian soils. The pigment producton by the molds belongs to a genus Monascus was investigated under the submerged culture. Mutagenesis of Monascus sp. KS 2 as the highest pigment production by NTG was made to increase pigment production. This mutant was examined to produce red and yellow pigment with 2.4 and 1.6 times higher than the parental isolates, respectively. The optimal cultural conditions for the pigment production by this mutant were: pH 6.0 , temperature
, rice powder 5%, and monosodium glutamate 0.15%.
Biological activities of the diethyl ether soluble toxin produced by Helminthosporium sativum
Lee, Sang-Sun ; Vick, Brady A. ; Stack, Robert W. ;
The Korean Journal of Mycology, volume 19, issue 2, 1991, Pages 128~135
Diethyl ether soluble toxin produced by H. sativum had the characteristics of helminthosporal as based on UV, GC-MS, and chemical analysis, but was not a helminthosporaI. It was speculated that it was a polymer of helminthosporal. It stimulated the productions of reducing sugar in the barly endosperm like gibberellic acid, but acted in the responses on the barley roots and coleoptiles like gibberellic acid. It seemed to be involved in Foliar and Root rot diseases with host specificity, based on the analysis of linear regression.
Colonial Morphology of Yeasts Grown on the Medium Containing Pigments Extracted from the Fruits of Gardenia jasminoides

The Korean Journal of Mycology, volume 19, issue 2, 1991, Pages 136~142
Colonial morphology of the various yeasts grown on the yeast morphology agar medium containing orange-yellow pigments extracted from the fruits of Gardenia jasminoides (GJPM) was investigated in hopes of the differential identification of yeasts on primary cultures. Colonies of Candida lusitaniae and Ca. guilliermondii on GJPM turned to prussian blue within three days of incubation and Ca. tropicalis and Ca. viswanathii turned to bluish gray but the latter species turned to deep blue after 7 days. Ca. krusei, Saccharomyces cerevisiae, and Torulopsis glabrata showed neutral gray, grayish green, and baby blue respectively after one or two weeks. However, the colonies of Ca. albicans and parapsilosis remained unchanged even after 20 days. Colonial color of Cryptococcus neoformans showing brown to purple brown was distinguishable not only from buff color of Cr. laurentii after one or two weeks incubation but also from those of Candida spp. Growth of certain species was promoted on GJPM. The findings clearly showed that Ga. jasminoides pigments medium was useful to the morphological differentiation of medically important yeasts which were often encountered in sputum or other clinical specimens.

The Korean Journal of Mycology, volume 19, issue 2, 1991, Pages 143~147
Botryosphaeria dothidea causing apple fruit rot was cultured in pectin-polypectate mineraI salts or apple mediumss, to investigate pectolytic enzyme production and activity. Exo-polygalacturonase(PG) and exo-polymethylgalacturonase (PMG) in apple medium showed maximum of activity to 6.4 and 7.2 units at six days of culture, respectively. Their maximum activity in pectin-polypectate mineral salts medium was 5.9 and 5.3 units at eight days of culture lower than in apple medium respectively. Endo-PG and endo-PMG in pecin-polypectate mineral salts medium were maximum of activity to 4.4 and 16.2 units at six and eight days of culture, respectively, but activities in apple medium were 3.2 and 6.7 units at eight days of culture. Activity of polygalacturonate-trans-eliminase(PGTE) and pectinmethyl-trans-eliminase(PMTE) was higher in pectin-polypectate mineral salts medium than in apple medium. Fungal growth was maximum at six and eight days of culture in pectin-polypectate mineral salts and apple medium, respectively.

Fungal ochratoxin A wes extracted and measured from the Korean traditional and fermented soybean foodstuffs (12 samples of Maeju, 28 samples of Dwangjang and 28 samples of Kangjang) collected from the whole nation wide regions. The various fungi were isolated from the foodstuffs and they were also examined whether the isolates produce ochratoxin A (OA) under the artificial conditions or not. Determinations of OA produced by the fungi were done with the antibody-attached CIA method, which was accurate or sensitive at the range of 20 pg per sample with a ninty percent recovery. Out of the 222 fungal isolates, 39 isolates produced the OA under the artificial conditions, and were identified as species of Aspergillus, Penicillium, Paecilomyces or other genera. The OA detected in all soybean foodstuffs was presumed to be originated from the first fermentation step of maeju.
