For 2 years
, study on development of cheap medium for Pleurotus ostreatus revealed that paper sludge contain more CaO and similar T-C, T-N,
, MgO but less
than any other medium material in chemical property. Mixed treatment (rice straw + paper sludge 10, 30, 50%, cotton waste + paper sludge 10, 30, 50%, cotton waste + rice hull 20 + paper sludge 10, 30, 50, 70%) is similar or fast a little in mycelial growth and is similar or fast
day in period of primordia formation than cotton waste medium, and in the yield to each medium type also increased but excepted in rice hull 20% + paper sludge 70%, especially mixed medium at 7:3 ratio of cotton waste and paper sludge is best treatment because it is increased to 21%. In economical analysis, mixed medium at 7:3 ratio of cotton waste and paper sludge is increased to 50% compared to cotton waste medium in relative income.

This study describes the effects of several components on PCR amplification used for RAPD. We used different concentrations of reaction components to obtaine discrete and reproducible PCR products from Pleurotus cornucopiae. The optimum concentrations of reaction components were found to be 80 ng of template DNA, 30 pmole of 10-mer primer,
, 50 mM KCl, 10 mM Tris-HCl(pH 9.0), 0.1% Triton X-100, 1.5 unit of Taq DNA polymerase (promega) in
reaction volume. The optimum annealing temperature was
. These results proved to be valuable for characterization of Pleurotus spp.

from Ganoderma lucidum was extracted from the mycelium of G.lucidum IY009 which was cultured in various carbon sources. The mycelium was shown to be capable of utilizing various carbon sources, e.g., soluble starch, fructose and glucose, and differs in morphology on carbon sources. In radioisotope assay, about
of glucose was to be incorporated in ganoderan of the mycelium. The monosugars of these ganoderan were mainly consisted of glucose, mannose, galactose. The galactose was not good carbon source for growing the mycelium but the best carbon source for producing the potentialized-ganoderan on the antitumor and anticomplementary activity. The tumor inhibition ratio of ganoderan-GAL, obtained from galactose medium, was 83.6% at the dose of 20 mg/kg/day. This crude polysaccaride was composed of five monosaccharide and the protein contained 16 amino acids. Also, ganoderan-GAL increased the anticomplementary activity than that obtained from any other media. This fact suggests that the structural differences of ganoderan influence the antitumor and anticomplementary activity.

Tile effects of addition of eggshell to sawdust substrate for the growth of F. velutipes were investigated. Eggshell used in this study contained 20.7% C, 0.81% N, 2530 ppm
and 44.37% Ca. The addition of eggshell resulted in the increase in bulk density and decrease of moisture content of the substrate. The addition of eggshell significantly increased the yield of the mushroom fruitbody. The addition rate of 15% (v/v), by 25% and at the rates of 5% and 10%, about 20%. Although the addition of eggshell to substrate did not improve the quality of mushroom, it increased the number of effective stipes as compared to control plot; approximately 13% more than in the control plot.

Antifungal protein from the hemolymph of larvae of Tenebrio molitor in Korea was partially purified by
open column chromatography and assayed for the activity spectrum using 3 kinds of yeast and 4 kinds of filamentous fungi. The crude antifungal protein showed static activity for a broad range of fungal species. Weak cidal effects were observed in growing yeast type cells, including Candida and Saccharomyces. The affected cells were changed from ovoid to swollen and spherical form in shape. For filamentous fungi including Aspergillus and Fusarium, the crude antifungal protein affected the spore germination and the hyphal growth but not the viability significantly.

A good mycelial growth of F. fraxinea was observed on CDA medium. The optimum temperature and pH for the mycelial growth of F. fraxinea was at
and pH 6.0, respectively. Glucose was found to be the best carbon source and arginine was favored as nitrogen source. When the basal medium was supplemented with organic acids, the best growth was shown in succinic acid and the poor growth was shown in oxalic acid. Thiamine.HCl showed the best results on the growth of this fungus on basal medium. Mycelial growth of F. fraxinea was quite good when oak tree sawdust was used to cultural substrates. The best mycelial growth was observed when 20% of rice bran was added as a supplement on sawdust substrates. Higher yield of F. fraxinea was observed on the medium with oak tree and acacia sawdust.

Phenotypic characteristics, pathogenicity and fungicides resistance of fifty one isolates of Botrytis cinerea obtained from various host plants were observed and determined. The relationships between these characteristics were also investigated on the basis of isolation host plants. The isolates of B. cinerea varied in the capacity of sclerotia formation and sporulation. The pathogenicity of 44 isolates from tomato, cucumber, and strawberry was significantly stronger with 3.2 cm in average diameter of necrotic lesions on cucumber leaves than that of seven isolates from other host plants such as orange, gerbera, ginseng, kiwi, grape, pear and from butter with 1.8 cm in average diameter of necrotic lesions. Benomyl resistance of 12 isolates from tomato plants was much higher with the
, 562 ppm than that of 19 isolates from various host plants. Diethofencarb resistance, however, of 11 isolates from strawberry plants was highest with the
, 210 ppm among isolates from other host plants. Polygalacturonase activity varied among isolates in the range of 0 to 103 unit and that of isolates from tomato, cucumber and strawberry was slightly lower than that of isolates from other host plants. No significant relationship between pathogenicity and fungicides resistance, polygalacturonase activity was found among 51 isolates of B. cinerea. Isozyme patterns of polygalacturonase produced from two strongly and weakly pathogenic isolates (FC122, KC6) were slightly different depending upon carbon sources during cultivation.

Morphological characteristics and pathogenicity of Rhizoctonia species causing blight diseases of turfgrasses were studied. The species were identified as Rhizoctonia cerealis Van der Hoeven, R. oryzae Ryker et Gooch, and R. solani
based on their morphological and cultural characteristics. Isolates of R. solani were assigned to anastomosis groups (AG) with cultural type 1 (1A), 2-2 (IIIB), and 2-2 (IV). R. cerealis, R. oryzae and R. solani induced sheath rot and foliar blight symptoms on creeping bentgrass (Agrostis palustris) and zoysiagrass (Zoysia japonica). Inoculation tests showed that disease severity with isolates of R. cerealis and R. oryzae were more serious to creeping bentgrass than zoysiagrass. AG 1(1A) isolates of R. solani were strongly pathogenic on creeping bentgrass, but moderate to zoysiagrass. AG 2-2 (III) isolates were moderately pathogenic to zoysiagrass, but weakly to creeping bentgrass. AG 2-2 (IV) isolates from zoysiagrass were moderately pathogenic to zoysiagrass, but weakly to creeping bentgrass.

The nutritional requirements of mycelial growth for Pleurotus spp. were studied. As the carbon sources, soluble starch and dextrin, nitrogen sources, arginine and ammonium tartrate, and calcium sources,
enhanced mycelial growth. Optimum C/N ratio was 100 : 1. On the base of results from the experiment on nutritional requirements, the following receipe is suggested for growth of Pleurotus spp.; starch 15 g, arginine 3.484 g, ammonium tartrate 3.06 g,
1.5 g for P. sajor-caju and 2.5 g for P. ostreatus.
0.02 g, optimum pH 6.0. This new synthetic medium is tentatively designated as Park's medium.
