  • 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.

  • This study was conducted to investigate the physicochemical characteristics, antioxidant capacities of Phellinus linteus and Ganoderma lucidum commercial tea products. The physicochemical characteristics included pH, Hunter's color values, soluble solid contents, evaporation residues, and ${\beta}$-glucan contents. The antioxidant capacities were measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities, ferric reducing antioxidant power (FRAP), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities, total phenolic contents (TPC), and total flavonoid contents (TFC). The pH, soluble solid contents, evaporation residues, and ${\beta}$-glucan contents were in the range of 4.43-7.05, $0.40-0.73^{\circ}Brix$, 62.04-258.84 mg/100 g, and 15.51-62.32 mg%, respectively. Hunter's color values (L, a, and b) indicated 41.76-55.02, -0.49-5.06, and 17.41-28.32, respectively. The antioxidant capacities showed $32.63-367.81{\mu}M$ GAE (DPPH radical scavenging activities), $321.86-1,035.19{\mu}M$ TE (FRAP), $703.50-1,091.83{\mu}M$ (ABTS radical scavenging activities), $286.56-916.00{\mu}M$ (TPC), and $85.33-635.33{\mu}M$ (TFC). Overall, P. linteus liquid tea 2 (PL2) and G. lucidum liquid tea 1 (GL1) showed high antioxidant capacities (p<0.05). The TPC and TFC were highly correlated with DPPH radical scavenging activities, FRAP, and ABTS radical scavenging activities (r=0.7298-0.9743), but the ${\beta}$-glucan contents were not correlated well with antioxidant activities tested (r=0.3146-0.6663).

  • Medicinal plant Rehmanniae Radix has long been used as traditional herbal medicine in Korea. In this study, we investigated quantitative changes of marker substance 5-hydroxymethyl-2-furaldehyde (5-HMF) in Rehmanniae Radix Preparata fermented with Ganoderma lucidum, Paecilomyces japonica, honey, and Nuruk, using HPLC according to the Korean Pharmacopoeia. As a result, 5-HMF was decreased in SDT and SYT, and increased in SST and SNT, comparing with control group. Quantitative increasing of 5-HMF is not exactly in direct proportion with fermentation, and it is need further studies to elucidate mechanism of quantitative changes by converted and newly produced substances with fermentation.

  • To estimate the inhibitory effect of some mushroom extract on melanin biosynthesis, we tested its inhibitory effects of five mushroom extracts on tyrosinase promoter in Bl6 mouse melanoma cells. In five mushroom extracts, Cordyceps militaris and Poria cocos exhibited low repression effect on tyrosinase promoter. However, Ganoderma lucidum, Paecilomyces japonicus, Phellinus linteus showed high repression effect, Especially, Paecilomyces japonicus and Phellinus linteus extracts had very higher repression effect approximately $81{\sim}83%\;at\;100{\mu}g/mL$. In the MTT assay, Paecilomyces japonicus and Phellinus linteus extracts exhibited high cytotoxicity. Therefore, repression effect of the extracts were closely connected with cytotoxicity.

  • To investigate antitumor components of Korean higher fungi, the carpophores of Ganoderma lucidum (Fr.)Karst. were collected at Gal-mae-ri in Gyeong-gi Province and extracted with 0.1N sodium hydroxide solution. The extract was purified by dialyzing through Visking tube and a dark brownish power was obtained. The antitumor activity of the fraction was tested against sarcoma 180 implanted in mice. The tumor inhibition ratio of the fraction against the tumor was 87.6% in doses of 50 mg/kg/day for the period of ten days. The tumor in five of 15 mice was completely regressed. The antitumor fraction was chemically analyzed and found to be a complex of polysaccharide and protein, from which four monosaccharides and eighteen amino acids were identified.

  • This study was carried out to investigate the dose dependent antifibrotic effects of G009, the water-soluble fraction of polysaccharide extracted from Ganoderma lucidum. The experimental hepatic cirrhosis was induced by bile duct ligation/scission (BDL/S) in rats. BDL/S rats in each group were dosed 0.5, 2, 5 or 10mg/rat/day orally for 4 weeks after the operation. Antifibrotic effects were evaluated by serum biochemical values, hydroxyproline contents, and light microscopical histology.

  • 정상 동물군의 GOT값 및 GPT 값이 각각 137.8$\pm$23.4 및 67.4$\pm$10.0 이었고 acetaminophen 투여군은 418.6$\pm$69.1 및 447.4$\pm$7.7로 증가하였으나 G009 투여군은 그 증가가 현저히 억제되었다. 즉 G009 10mg/kg 투여군은 GOT 및 GPT 값이 192.6$\pm$19.2 및 144.8$\pm$28.7에 그쳐 각각 GOT 및 GPT 값의 상승이 80.5% 및 79.6% 억제되었고 20mg/kg 투여군은 90.8% 및 86.6% 억제되었다. 그러나 Licovek 은 50mg/kg의 투여군에서 이와 유사한 효과가 관찰되었다. 또한 간 절편의 조직학적 관찰 결과 acetaminophen 투여 대조군이 간세포 괴사등 심한 조직 괴사를 보인 반면 G009 10mg/kg 및 20mg/kg 농도에서는 간장 손상이 매우 경미함을 확인할 수 있었다.
