The objective of this research was to determine the effect of light quality on formation of fruit body primordia (FBPs) of Ganoderma lucidum. To achieve this 5 isolates of the fungus that develops fruit body primordia on nutrient agar media were incubated with or without continuous irradiation. The fluorescent lamps used different colors such as black light blue (BLB), pure blue (P-B), pure green (P-G), pure yellow (P-Y) and pure red (P-R). Effect of periodic light and dark exposures on FBP formation of isolate Gl-009 was investigated. The FBP formation in G. lucidum isolates was also tested under monochromatic light produced by the combination of interference filters and colored glass filters. Three isolates produced FBPs under all kinds of fluorescent lamps, whereas two induced FBPs only under visible light except for BLB fluorescent lamp. However, these isolate did not form FBPs in the dark. The FBP was formed at light intensity from 0.05 to
, and begun to reduce its number as light intensity increase over
. When the isolate was incubated under periodic light and dark exposures, the number and weight of FBP increased as compared with those under continuous light. Initiation of FBP requires at least 4 days of light illumination. Although isolate Gl-003 produced FBPs in a wide range of 400 to 800 nm, other four isolates had two effective regions 400 to 500 nm and 700 to 750 nm in FBP formation.

Media development of Pleurotus ostreatus were analyzed to recognize the compositional differences depending on rice straw and waste cotton stuff media. Yields of add the rice bran 20% to the waste cotton stuff were increment 11% as compared with rice straw media. Crude protein of products to the waste cotton stuff media on Pleurotus ostreatus was a much and crude ash was less than of rice straw media. Glutamic acid was most and cystine was lowest among the amino acids of Pleurotus ostreatus. Total amino acids and essential amino acids of waste cotton stuff were much than of rice straw media.

Five species belong to three genera of the Laboulbeniales were collected on Blattidae (Blattodea), Nitidulidae and Carabidae (Coleoptera) from Kwangneung Kyeonggido and some the others. They are Herpomyces periplametae Thaxter on Periplaneta japonica Karny, Herpomyces stylopygae Spegazzini on Blatta orientalis (L)., Laboulbenia yamadae Ishikawa ex Terada on Chlaenius variicornis Morawitz, Rickia pallodina Thaxter on Pallodes umbratilis Reitter and Rickia papuana Thaxter on Pallodes umbaratilis Reitter. Among these species, Herpomyces periplametae Thaxter and Rickia pallodina Thaxter are new to Korea.

This study was carried out to obtain data concerning the genetic variability of Pleurotus ostreatus. Monospores of P. ostreatus were isolated and cultured to estimate differences in the rate of mycelial growth and genetic similarity among the isolates. Although the overall growth rates were slow compared to their parental dikaryon except 2-MI 4, significant differences in the rate of mycelial growth were observed among isolates. Random amplified polymorphic DNA (RAPD) analysis using twenty six random primers showed 345 polymorphic DNA bands from 35 monospore isolates and their parental dikaryon. DNA bands ranged from 0.1 to 4.0 Kb in size. Most various polymorphic DNA bands within monospore isolates were obtained when we used J (OPA-01) or W (OPB-04). The 36-MI 103 showed totally different band patterns from those of the others. RAPD analysis revealed that there is approximatly 75% genetic similarity between monospore isolates and their parental dikaryon except 36-MI 103, which showed only 49% genetic similarity. In addition, genetic similarity degrees were classified into four groups: I (parental dikaryon), II (fast growing type), III (moderate growing type), and IV (slow growing type). However, there is no correlation between mating type and mycelial growth rates.
Isolation of a Thermophilic Mutant, Talaromyces luteus 2004 in relation to the Regulation of Carboxymethylcellulase Production and Enzymatic characteristics

Talaromyces luteus 2004, a thermophilic mutant of T. luteus 6112 was obtained by mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. T. luteus 2004 produced thermophilic carboxymethylcellulase (CMCase), and other polysaccharide enzymes: avicellase, xylanase, and
. Induction of CMCase production was shown at the highest level in 3% carboxymethylcellulose (CMC) minimal broth, indicating that CMC could work as an inducer. However, glucose and D-cellobiose showed catabolite repression for CMCase production which was under the control of CMC utilization. Optimal conditions for CMCase activity were at
and pH 4.0, suggesting that CMCase of T. luteus 2004 was a thermophilic enzyme.

This study was carried out to obtain the basic data on artificial culture of Phellinus linteus. The optimum condition for the mycelial growth was
. The carbon sources such as D-glucose, D-mannose and Dextrose were favorable to mycelial growth. As nitrogen sources, peptone, cassamino acid and glutamic acid appeared to be favorable. The optimum C/N ratio was about 20:1, when 2% of glucose was provided as a carbon source. The better organic acids and vitamin among tested ones were gallic, silicic acids and biotin. The mineral nutrients of
were effective and the optimum concentrations were 0.05, 0.001, 0.02 and 0.003%, respectively.

The effects of addition of dried apple pomace to sawdust substrate on the growth of Flammulina velutipes were investigated during the period of 2 years
. Dried apple pomace used in this study consisted of 44.6% C, 0.54% N, 0.16% CaO, 0.16%
, 0.11% MgO and 1.29%
(pH 4.4). The addition of 15% apple pomace (v/v) increased the yield of the mushroom fruitbody by 9%, and period of primordia formation was similar regardless of the treatments. In economical analysis, the addition of 15% apple pomace (v/v) increased 29% compared to the control treatment in relative income.

Two depsides, medicinal herb products isolated from the methanol extract of Umbilicaria esculenta, inhibited human synovial fluid Phospholipase
of 0.22 and 0.26 mM, respectively). In the course of screening for antiinflammatory compounds from natural products, we successfully isolated two depsides
inhibitory compounds, Orcinol and methyl orsellinic acid. The compounds were identified as orcinol and methyl orsellinic acid on the basis of various NMR studies including
and DEPT experiments.
