The Flora of Higher Fungi in Mt. Muhack Areas(III)
Park, Seong-Sik ; Cho, Duck-Hyun ; Lee, Ji-Yul ;
The Korean Journal of Mycology, volume 15, issue 2, 1987, Pages 71~75
More then 120 species of higher fungi were collected in Mt. Muhack areas during the period from May, 1985 to September, 1986. These higher fungi were identified. As a result of identification, Hygrocybe ovina(Fr.) Kuhn., lnocybe albodisca Peck., I. calospora Que'I., and I. kobayasii Hongo were new to be Korea.
Notes on Unrecorded Fleshy Ascomycetes in Korea
Hong, Soon-Woo ; Jang, Yong-Suk ;
The Korean Journal of Mycology, volume 15, issue 2, 1987, Pages 76~79
More than 100 samples of the Ascomycetous fleshy fungi were collected and investigated. Among them, 3 genera and 9 species were confimed as unrecorded ones in Korea. Unrecorded genera were Tarzetta, Hypocrea and Mollisia. Unrecorded species were Cyathipodia villosa, C. cupuliformis, Cudonia confusa, Tarzetta catinus, T. cupularis, Rutsroemia petiolorum, Mollisia ventosa, Hymenoscyphus pileatus and Hypocrea rufa.

The author isolated high cellulolytic fungi from natural sources and determined optimal condition of protoplast formation and fusion as fundamental step for improvement of the isolated it's cellulolytic ability. Three different cellulolytic fungi, such as Aspergillus sp., Penicillium sp. and Trichoderma sp., were isolated from soil. Their cellulolytic activities were compared with that of Aspergillus niger which was useful industrially and had cellulase activity. It was Aspergillus sp. that showed the highest activity of all these four fungi. And then it was followed by Penicillium sp., Trichoderma sp., and Aspergillus niger in order. An auxotrophic mutant of Aspergillus sp. was obtained by UV mutagenesis method. Having try to produce protoplast from mycelia, the author found that
, at pH 6.0, was effective cell-wall lytic enzyme. And the optimal concentration of this enzyme was 5,000 unit/ml. Regeneration rates of wild type, met. auxotroph and arg. auxotroph, in presence of osmotic stabilizer, were 7. 0%, 7. 5% and 5.2%, respectively. PEG with M.W. 6,000 was effective stimulator for protoplast fusion in the concentration of 30% (W IV). In such a condition, we obtained 1.2% cell fusion rate.

The in vitro interactions between antibiotics(ampicillin, kanamycin, cephalexin, oxytetracycline and chloramphenicol) and ginseng saponin were studied by the chessboard method against bacteria(Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Mycobacterium smegmatis). Ampicillin, kanamycin, oxytetracycline and chloramphenicol against Bacillus subtilis, and ampicillin and cephalexin against Staphylococcus aureus were synergistic in the presence of ginseng saponin. Whereas kanamycin, oxytetracycline and chloramphenicol against Staphylococcus aureus, and ampicillin, Kanamycin, cephalexin, oxytetracycline and chlorampheniol against Escherichia coli, and ampicillin, kanamycin, and chloramphenicol against Pseudomonas aeruginosa, and ampicillin and chloramphenicol against Mycobacterium smegmatis were indifferent in the presence of ginseng saponin. Antagonisms between antibiotics and ginseng saponin were not observed in this study.
Harmful Fungi Associated with Rice Straw Media for Growing of Oyster Mushroom, Pleurotus ostreatus.
Shin, Gwan-Chull ;
The Korean Journal of Mycology, volume 15, issue 2, 1987, Pages 92~98
Twelve species of fungi were isolated from rice straw media for oyster mushroom cultivation. Trichoderma, Aspergillus and Rhizopus were the predominant fungi. Seven species of Trichoderma were isolated and identified from the rice straw media and the order of their frequency in the media was pseudokonigii, aureoviride, viride, harzianum and koningii. Occurrence of harmful fungi in mushroom houses become more severe as the number of cultivation times increased, and that was more severe in spring culture than in autumn culture. Mycelial growth and sporulation of Trichoderma, Aspergillus and Rhizopus were fovorable on the media appended with extracts of rice straws and oyster mushrooms. This results indicate that the rice straw media and mushrooms give favorable conditions for the occurrence of the fungi in the mushroom houses. Mycelial growth of Trichoderma spp. was favorable on sawdust extraction media and rice bran extraction media, and the spawns inoculated at the mushroom beds present media of the fungi.

The production and properties of laccase(E.C.188.8.131.52) from Coriolus versicolor were studied. The results were as follows; The nutritional optimum conditions for laccase production were 1% indulin At, 0.3% peptone 0.1%
, 0.1 mg%
.and 0.005 mg% thiamine HCI. The optimum temperature and pH of laccase production were

Nutritional characteristics and cultural conditions for trehalose synthesis and mycelial yield of Pleurotus sajor-caju and Pleurotus ostreatus 201 in submerged culture were investigated. The results were as follows: Among the carbon sources, glucose was most excellent for trehalose synthesis and mycelial yield. The optimal concentration of glucose was 1%. Among the nitrogen sources, peptone was most excellent for trehalose synthesis and mycelial yield. The optimal concentration of peptone was 0.05%. The optimal concentration of
for trehalose synthesis and mycelial yield was 0.1%,0.04% and 0.2%,0.04-0.08%, respectively. The optimal temperature and pH for trehalose synthesis were
and pH 5.5. but optimal temperature and pH for mycelial yield were
and pH 5.5. The maximum yield of trehalose was obtanined after 10 day cultivation.
