  • Anticomplementary activity of 61 strains of Korean higher fungi was screened for immunostimulation. Extracts from 11 of 61 strains including 5 of Ganoderma lucidum, 3 of Lentinus edodes, 2 of Cordyceps sp. and 1 of Agaricus campestris, showed higher anticomplementary activity than krestin which was immunopotent extract from Japanese Coriolus versicolor. The most potent anticomplementary activity was found with extract from Lentinus edodes IY105 whose complement consumption was 31.7%.

  • This study was investigated the effects of water soluble extract of Ganoderma lucidum kale juice and soidium dextrothyroxine on lipid components in serum of hypercholesterolmemic rats in vivo in order to prevent in cardiovascular disease. Total cholesterol concentrations in serum were significantly increased after feeding cholesterol diet group compared with control group and were significantly increased after feeding cholesterol diet group compared with control group and were lower in Ganoderma lucidum kale juice and sodium dextrothyrioxine diet groups than in control group. Ratio of high density lipoprotein cholesterol concentration to total cholesterol were significantly highest in sodium dextrothyroxine fed groups among diet groups and were higher in Ganodrma lucidum and kale juice fed group than in control group. Phospholipid concentrations in seurm were significantly lower in Ganoderma lucidum kale juice and sodium dextrothyroxine(1.25mg/kg diet) fed groups than in control group and triglyceride concentra-tions were lower in Ganderma lucidum sodium dextrothyroxine fed groups than in other groups. Triiodothyronine concentration in serum were lower in Ganoerma lucdum and kale juice fed groups than in the other groups while it was higher in sodium dextrothyroxine diet group than in other groups. Tetraiodothyronine concentrations is serum were remakably higher in sodium dextrothyroxine fed group than in other groups. Blood glucose concentration was lower in cholesterol diet group than in other groups but was higher in sodium dextrothyroxine diet group than in other groups.

  • A study was carried out to explore the method for the germination of the spore of Ganoderma. Three strains of Ganoderma were examined using 2 different media such as PDA and LBA at three different temperatures. As it has been known the germination rate was very low under all the conditions examined. G. lucidum ASI 7004 showed 0.02% germination on both media at $25^{\circ}C$ and $30^{\circ}C$ respectively. The germination rate of ASI 7091 was 0.05% on PDA medium at $30^{\circ}C$. The germination rate of G. oregonense ASI 7067 was 0.67% on PDA at $35^{\circ}C$. LBA medium was found to be inadequate for the germination of Ganderma species in this study. In a consequent study, four mating types of G. oregonense such as $A_1B_1,\;A_1B_2,\;A_2B_1\;and\;A_2B_2$ were identified.

  • Factors affecting the productivity of cellulolytic enzymes and the mycelial growth of Ganoderma lucidum CAFM 9065 were examined in synthetic media. Among the carbon sources tested, Na-CMC was the best for the production of avicelase CMC ase, and cellobiose for ${\beta}-glucosidase$. Soluble starch and cellobiose were the best for the mycelial growth. The optimum concentration of Na-CMC for the production of the enzymes was 1.0 %, and mycelial growth increased remarkably with the higher concentration of Na-CMC. Glucose inhibited the production of the enzymes, but stimulated the mycelial growth. Among the nitrogen sources used, peptone was the most effective for the production of the enzymes, and the appropriate concentration of peptone was 0.2%. The mycelial growth was stimulated with the increase of the concentration of peptone up to 0.5%. The optimum concentration of $KH_2PO_4$ for the production of the enzymes and mycelial growth was 0.3 and 0.2%, respectively. The optimum concentration of $MgSO_4{\cdot}7H_2O$ for the production of the enzymes and mycelial growth was 0.02%. The production of the enzymes was facilitated by folic acid at a low concentration (0.03 mg/l), and mycelial growth by inositol. The optimum temperature for the production of the enzymes and mycelial growth was $30^{\circ}C$. The optimum pH for the production of avicelase and ${\beta}-glucosidase$ was 5.0 equally and CMCase 5.5. The activities of avicelase and CMCase were the highest at 8 and 10 days of culture, respectively and that of ${\beta}-glucosidase$ at 16 day culture. The growth of mycelium was the highest at 12 days of culture at pH 5.0.
