The purpose of this study was to investigate the physiological functionality of Coriolus versicolor Quel (CV) and Ganoderma IUCIdum (Fr.)Karst (GL) by estimate the proximate composition and content of antioxidant components. 1. In the physicochemical property. the content of proximate composition of GL was higher 08.28% of moisture, 10.3% of crude protein, 78.4% of crude fiber) than that of CV, but the content of crude lipid and ashes of GL was higher than that of CV. 2. CV had relatively higher content of antioxidant components such as total phenol, carotenoids and v itamin C. than GL did. Antioxidant mineral components such as magnesium and zinc also had relatively higher in CV than in GL. 3. TBA value, conjugated diene production, LDL oxidation, DPPH of methanol extracts in CV and GL were as high as a-Tocopherol.

In orde to investigate free sugar, sugar alcohol, amino acid and mineral contents of edible mushrooms, hentinus edodes, Auricula-Jude and Coriolus Versicolor were analyzed. 1. In each of the three mushrooms, glucose, fructose, xylose, trehalose, mannose and mannitol were identified and in the hentinus edodes and Auricula-jude, the major free sugar was trehalose, respectively and increasing sequence in amount of free sugars were mannitol, mannose, fructose, glucose, on the other hand that lowest amount was Xylose. The relatively richest were glucose, fructose, trehalose, mannose, on the other hand lower amount of sample, Coriolus Versicolor were mannitol and Xylose. 2. In each of the three samples, essential amino acids were high amounts, especially good taste component, glutamic acid was higher. 3. The mineral p Contents$(925\~115mg)$ were highest and Mg was higher amount, in hentinus edodes and Auricula-jude, K, Na, Ca, Cu, Zn, etc were identified, In Coriolus versicolor, K content was highest, on the other hand, Sequence of mineral amount was Ca, Fe and Na.

Effects of buprofezin, a chitin synthesis inhibitor of insects, on mycelial growth, protoplast formation and reversion of Coriolus versicolor, Ganoderma applanatum and G. lucidum were investigated. The mycelial growth of C. versicolor, G, applanatum and G, lucidum was severely inhibited by buprofezin treatment, and the inhibition rate severely as the concentration of the buprofezin increased. Aerial mycelia and oidia formation of the mushrooms were increased by buprofezin treatment, but mycelial morphology was not changed. The rate of protoplast formation and reversion of G, applanatum was greatly increased by the treatment of the buprofezin, while that of G. lucidium was decreased. The rate of protoplast formation of C. versicolor was also increased when buprofezin was added to the medium, but the rate of protoplast reversion was not affected by the treatment, From the results obtained in this experiment, we found that the rate of protoplast. formation and reversion was increased by the treatment of the buprofezin in the mushrooms such as C, versicolor and G, applanatum, whose mycelial growth was fast on the medium, while that of G. lucidum, whose mycelial growth was relatively slow, was decreased by the treatment.

Effects of nitrogen and carbon sources on the decolorization rate of poly R-478 dye by a white rot basidiomycete Coriorus versicolor IFO 30388 were examined. The fungus exhibited 87.2% of decolorization rate when it was cultured in the state of stationary in a nitrogen-limited medium (pH 4.5) which contained 2.0% glucose, 0.04% ammonium tartrate, 0.02% poly R-478 dye, 2% $KH_2PO_4$, 0.5% $MgSO_4{\cdot}7H_2O$, 0.1% $CaCl_2{\cdot}2H_2O$, 0.002% thiamine-HCl and 10 mM 2,2 dimethylsuccinate (sodium) at $28^{\circ}C$ for 10 days. Decolorization of the dye occurred in the presence of nitrogen source in the medium and decolorization rate increased rapidly after depletion of $NH_4^+$ from the medium.

An anticancer substance was prepared by ethanol precipitation of the hot water extract of culture mycelia of Conolus versicolor KFCC 30388. After 6 days of fermentation, the mycelia growth reached the peak and reducing sugar consumed almost all. HTCFA method has been employed for three human cancer cell lines, Hep-2(larynx cell), A-427 and Calu-3 (lung cell). Anticancer activities in A-427 and Calu-3 were 8.4 and 9.8% survival rate, respectively. The chemical analysis of the extract from the mycelia showed 42.2% of polysaccharide and 10.5% of protein. The polysaccharide consisted of five kinds of monosaccharides, L-glucose, D-glucose, galactose, mannose and xylose.

Polysaccharide fraction isolated from Coriolus versicolor (Copolang) was studied on the antitumor activity and immunostimulation activities with reference to PS-K. Copolang showed nearly equal antitumor activities to the PS-K and exhibited marked augmentation effects on the antibody mediated hypersensitivity reaction, delayed type hypersensitivity reaction and NK-cell activity in tumor bearing mice. But it did not show any noticeable effect on the antibody secreting cell and macrophage function in normal mice. These results indicate that the antitumor activity and immunostimulating effect of Copolang are comparable to those of PS-K.

The ethyl acetate extracts from the liquid cultures of Coriolus versicolor, Phellinus linteus, and Hericium erinaceus showed significant antibacterial activities against Escherichia coli K88, E. coli K99, E. coli 987P, and Salmonella typhimurium 14058 causing bacterial diarrhea in Korean house pigs and chicken. Of these extracts, Coriolus versicolor extract showed the highest antibacterial activity. In addition, these extracts also showed significant growth inhibition against Staphylococcus aureus CARM3230 and E. coli CARM1381 which are known as kanamycin and ampicillin-resistant strains. These results showed that the mushroom extracts could be developed as a livestock feed additives that can replace commercial antibiotics, and also could be good resources for the development of a new antibacterial agent.

The cultural conditions in shake flasks were investigated under which maximum amounts of laccase produced by a strain of white-rot fungus Coriolus versicolor CV3. The enzyme yields on potato-malt extract medium by the fungus were higher than on other media consisted of onion infusion or malt extract, with maximum activity of $1.50unit/m{\ell}$ culture or 119.5 unit/g mycelium at 11 days of incubation. Maximum yields of laccase and growth were obtained by supplementation of yeast extract or potassium nitrate to the potato-malt extract medium. Addition of 2.5-xylidine at $4{\times}10^{-4}M$ concentration to the medium induced the laccase production 3.1-fold higher than the basal level, while the mycelial growth was somewhat repressed. The pH optimum for the growth and laccase formation by the fungus was between pH 4 to 4.5.

This study was executed to investgate the effects of medium components on liquid culture in the flask culture of Coriolus versicolor. This work was focused on raising the mycelial growth and the polysaccharide production. In order to optimize the medium, different carbon and nitrogen sources were investgated. Glucose and yeast extract were chosen for the production of mycelia and polysaccharide as carbon and nitrogen sources, respectively, in the flask culture. For the mycelia growth and polysaccharide production, the medium contained glucose 20g/L, yeast extract 6g/L, $KH_2PO_4$ 0.46g/L, $MgSO_4.7H_2O$ 0.5g/L. The liquid culture conditions for the mycelial growth were $27^{\circ}C$, 200rpm and working volume 100mL using 250mL flask.

Decolourization potential of white rot fungal organism, coriolus versicolor, was investigated in a batch reactor, for textile dye industry wastewater. The influence of process parameters like pH, temperature, agitation speed and dye wastewater concentration on the decolourization of textile dye wastewater was examined by using Response surface methodology (RSM). The maximum decolourization was attained at: pH- 6.8, temperature - $27.9^{\circ}C$, agitation speed - 160 rpm and dye wastewater concentration - 1:2. From the analysis of variance (ANOVA) results it was found that, the linear effect of agitation speed and dye wastewater concentration were significant for the decolourization of textile dye wastewater. At these optimized condition, the maximum decolourization and chemical oxygen demand (COD) reduction was found to be 64.4% and 79.8% respectively. Various external carbon sources were tried to enhance the decolourization of textile dye wastewater. It was observed that the addition of carbon source enhances the decolourization of textile dye wastewater. Kinetics of textile dye degradation process was studied by first order and diffusional model. From the results it was found that the degradation follows first order model with $R^2$ value of 0.9430.
