  • Fifty six mycelial cultured Basidiomycetes were screened for their inhibitory effects against prolyl endopeptidase(PEP), acetylcholine esterase(AChE) and thrombus coagulation. Out of them, methanolic extract of mycelium and/or ethylacetate(EtOAc) soluble fraction from culture broth of Peniophora quercina, Amanita aspera, Phellinus chrysoloma, Grifola frondosa, Wolfiporia extensa, Clavicorona pyxidata and Phanerochaete sordida inhibited more than 90% of PEP activity at 40 ppm. The extracts of Lenzites betulina, Phellinus chrysoloma, Wolfiporia extensa, Phanerochaete sorrlida, Hypocrea nigricans, Coriolus azureus, Flammulina velutipes, Phlebiopsis gigantea and Bondarzewia montana exhibited about 40% of inhibitory activity against AChE at 40 ppm. In thrombin times assay, the extracts of Amanita aspera, Oxyporus latemarginata, Peniophora quercina, Fomes fomenfarius, Trametes versicolor, and Phlebiopsis gigantea delayed coagulation of thrombus about two to three times over control at ca 550 ppm. In activated partial thromboplastin times assay, none of the tested Basidiomycetes showed significant effect.

  • To investigate the hemolytic toxicities of the Korean basidiomycetes, the cold-water extracts of 22 wild mushrooms were tested for their hemolytic activities on the erythrocytes of a mouse and a rat. As a result, three species including Collybia confluence, Laccaria vinaceoavellanea and Lenzites betulina showed strong hemolytic activities. Of these, L. vinaceoavellanea retained more than 80% of its hemolytic activity even after it was boiled for 30 minutes, while the other two were inactivited in five minutes.

  • Background : This study was to investigate existing studies on the mushroom Phellinus linteus for possible applications in treating hard to cure diseases and uses in herbal acupuncture as the above is known to have an anti-cancer effects and stimulating the immune system. Results : Based on the literary consideration, the following results were obtained : 1. Proteins and polysaccharides of the Class Basidiomycetes activate the host immune system for anti-cancer action without known side effects, thus it can be given for the prevention and treatment of cancer as a supplement. Phellinus linteus mushroom showed the most significant effects. 2. The Phellinus linteus mushroom is a fungi in the family Hymenochaetaceae and Phellinus, under the class Basidiomycetes. Phellinus linteus can be often found on the trunk of mulberry trees and other latifoliate trees. 3. The characteristics of Phellinus linteus are sweet, neutral in temperature, non-toxic, dissipate the stagnated blood, stop bleeding, invigorate the blood circulation and remove stasis, and nourish qi. It has been used for treating continuous menstrual discharge among the female patients and removing masses in the abdomen to name a few. 4. Phellinus linteus contains agaric acid, fatty acid, C23 and other numerous enzymes. 5. Phellinus linteus is known to have anti-cancer and anti-oxidant effects, stimulation of the immune system, as well as anti-inflammatory effects, inhibition of angiogenesis, and analgesic actions.

  • Fruit bodies of the wood rotting basidiomycetes naturally grown in middle part of Korea were collected from August 1989 to May 1992 and identified to 24 genera and 31 species. Species diversity was differed little from areas, but index of species diversity was higher in Mt. Songni and Mt. Duckyu than that in other areas. The dominant species were Coriolus versicolor, Daedalea dickinsii, Daedaleopsis styracina, Lenzites betulina and Schizophyllum commune.

  • Depending on the mode of nutrition exploitation, major fungal guilds are distinguished as ectomycorrhizal and saprotrophic fungi. It is generally known that diverse environmental factors influence fungal communities; however, it is unclear how fungal communities respond differently to environment factors depend on fungal guilds. In this study, we investigated basidiomycetes communities associated with Quercus mongolica using 454 pyrosequencing. We attempted to detect guild pattern (ectomycorrhizal or saprotrophic fungal communities) by comparing the influence of geography and source (root and surrounding soil). A total of 515 mOTUs were detected from root (321) and soil (394) of Q. mongolica at three sites of Mt. Jeombong in Inje County. We found that patterns of diversity and community structure were different depending on the guilds. In terms of alpha diversity, only ectomycorrhizal fungi showed significant differences between sources. In terms of community structure, however, geography significantly influenced the ectomycorrhizal community, while source appeared to have a greater influence on the saprotrophic community. Therefore, a guildbased view will help to elucidates novel features of the relationship between environmental factors and fungal communities.

  • This study was designed to develop functional drink from jujube extract through a simple submerged culture of three basidiomycetes species. The optimum Brix and pH of the jujube extract for culturing the Ganoderma lucidum appeared to be 5 Brix and pH 4. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Coriolus versicolor appeared to be 5 Brix and pH 5. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Phellinus igniarius appeared to be 3 Brix and pH 5. For the maximum mycelial production eighteen days of culture period was required for Phellinus igniarius. The antitumor activity of the polysaccharides extracted from the fermented drinks was demonstrated through the tumor cell line experiments. The $IC_{50}$ values of the jujube drinks fermented with Ganoderma lucidum and Phellinus igniarius against stomach cancer cell line appeared to be one fourth that of the jujube drink which was not fermented with basidiomycetes.

  • The aims of this study were to investigate various components and their physiological activities of Sarcodon aspratus (Berk.) S. Ito which grows wildly in Korea, belonging to the family Thelephoraceae. The analysis of the powered carpophore of this fungus by TLC and an amino acid autoanalyzer revealed that it contained twenty-one free amino acids and that twenty­two total amino acids were identified in its acid hydrolysate. These amino acids were also quantified.

  • To investigate the fibrinolytic activities of the Korean basidiomycetes, the Extracts of 50 wild mushrooms were tested for their fibrinolytic activites. Extract from Tricholoma sejunctum showed 175% increased activity to that of plasmin 1.0 U/ml. Marasmius siccus showed 54% of activity, and Laetiporus sulphureus var. miniatus and Macrolepiota procera, 43% and 26% activities, respectively to that of plasmin. But, Cystoderma amianthinum, Lepiota sp., Coprinus sp., Lycoperdon sp. were less than 10% of plasmin activity.
