  • To develop basidiomycetes-fermented cereals with hypoglycemic property, inhibitory effects of basidiomycetes mycelia and basidiomycetes-fermented cereals on postprandial glucose were investigated. In vitro effect of basidiomycetes mycelia on retarding the membrane transport of glucose was compared with pectin. For basidiomycetes mycelia, $13.1{\pm}3.6{\sim}41.8{\pm}8.0%$ of total glucose remained in inner solution of dialysis membrane after dialysis for 120 min, indicating that most of basidiomycetes mycelia might effectively retard membrane transport of glucose. Glucose tolerance of basidiomycetes mycelia and basidiomycetes-fermented cereals was tested on streptozotocin-induced diabetic rats administrated with maltose. Postprandial glucose levels of basidiomycetes mycelia, $389.4{\pm}43.8{\sim}426.3{\pm}49.4mg/dL$, were considerably lower than that of control, $535.3{\pm}78.6mg/dL$, at 30 minutes after maltose administration. Namely, basidiomycetes mycelia showed better postprandial glucose lowering effect than pectin. Brown rice and barley fermented with Paecilomyces japonica showed much lower postprandial glucose level than raw brown rice and barley, especially hypoglycemic effect of barley fermented with Paecilomyces japonica was significant.

  • During a week from 6th August in 1976 to survey the fungal flora on higher fleshy fungi around Mt. Jogye 193 specimens were collected and then examined tentatively. As a result fo identification except several troublesome ones it was known that they lie within 66 genera, 110 species, 3 varieties, and 2 forms. Out of them five genera, Eutypa, Sarcosoma in Ascomycetes, and Corticium, Heimiella, Clitopilus in Basidiomycetes were confirmed as unrecorded genera to Korea. And therefrom 26 species and 1 form corresponding almost to the fourth of sum were identified as unrecorded species to Korea, among which Basidiomycetes are provided with descriptions and figures in this survey report.

  • For screening of biological activities of culture broth of some wood rotting basidiomycetes, antimicrobial activity, plant growth regulating activity, antitumor activity, and various enzyme activities were checked. Coriolus versicolor 5129 and C. pubescens 5131 strains showed inhibition activity against gram-positive bacteria and Lenzites betulina 8029 strain showed the activity against gram-negative bacteria. L. betulina 8085 inhibited the growth of both bacteria and plant pathogenic fungi. All of tested basidiomycetes inhibited the germination and growth of radish and cabbage at concentration of 0.8ml/ml. Especially, Fomitopsis pinicolor 8059 and Fomitella fraxinea 8084 showed strong inhibition activity. In contrast, Bjerkandera adusta 8054 stimulated the growth of cabbage and radish at concentration of 0.4 and 0.2ml/ml. All polysaccharides from tested basidiomycetes showed anti-tumor activity against sarcoma 180 and the stronger antitumor activity was observed in L. betulina 8029 and unidentified 8058 strain. All tested basidiomycetes had also an ability to degrade cellulose and lignin.

  • To find anititumor metabolites in Korean basidiomycetes, the shake-cultured mycelia of eight of the higher fungi were extracted with hot water and the extracts, after being partially purified, were subjected to in vivo antitumor test. When administered i. p. at the dose of 30mg/kg/day for ten consecutive days into the female ICR mice, which had been implanted with $1{\times}10^{6}$ / cells of sarcoma 180 twenty four hours before the first injection, the extracts of Agaricus campestris, Lyophyllum decastes, Lyophyllum ulmarium, Armillaria Tabescence and Calvatia exipuliformis respectively showed inhibition ratios of 64.1%, 65.45, 60.-%, 53.0 and 49.3%. These five species were selected for further study, whereas the extracts of Phallus impudicus, Coprinus comatus and Pholiota squarrosa whih showed the inhibition ratios of 31.2%, 33.5% and 19.0% were discontinued.

  • Basidiomycetous fungi are one of the most potent biodegraders because many of its species grow on dead wood or litter, in environments rich in lignocellulose. For the degradation of lignocellulose, basidiomycetes utilize their lignocellulytic enzymes, which typically include laccase (EC 1.10.3.2), lignin peroxidase (EC 1.11.1.14), xylanase (EC 3.2.1.8), and cellulase (EC 3.2.1.4). In recent years, the practical applications of basidiomycetes have ranged from the textile to the pulp and paper industries, and from food applications to bioremediation processes and industrial enzymatic saccharification of biomass. Recently, spent mushroom substrates of edible mushrooms have been used as sources of bulk enzymes to decolorize synthetic dyes in textile wastewater. In this review, the occurrence, mode of action, general properties, and production of lignocellulytic enzymes from mushroom species will be discussed. We will also discuss the potential applications of these enzymes.

  • To investigate the antibiotic constituents of Korean basidiomycetes the carpophores of the wood-rotting basidiomycetes were collected from several locations of Korea, and from them 17 mycelial strains were isolated on potato-dextrose-agar plates supplemented with tetracycline ($20\;{\mu}g/m{\ell}$. The isolated strains were shake-cultured in glucosepeptone-yeast extract medium and then the antibacterial activities of the culture filtrates were assessed by disc-plate method. Among them, 12 strains (70.6%) were active, and basidiomycete strain LMCB-109 (Daedalea quercina) and LMCB-116 showed potent activities against all the six bacterial target organisms including Serratia marcescens.

  • The grains were used as solid-substrate for the cultivation of basidiomycetes. The grains were fermented with Ganodema lucidum 7094, Fomitella fraxinea 81003, Phellinus igniarius 26005, and its free sugar composition was investigated. For the mass cultivation of mycelia, the hydrated grains with cold water were put into the plastic bottle. The mycelial growth rate in the bottled grains was high in the early stage with inoculation of homogenized mycelium. The activity of mycelium was maintained by adding sterilized water in the middle of cultivation. There was marked difference in the content of total free sugar and composition ratio of free sugar according to kinds of basidiomycetes. The content of free sugar increased far more in grains fermented with mycelium than in grains which was not fermented.

  • The properties of various grains used for the solid-state cultivation of basidiomycetes were examined. The hydration time with cold water was 10 hours for malt soybean. The required hydration time for Job's tears, barley and wheat was 4, 6 and 12 hours, respectively, but the final moisture content ranged from 30 to 48 %, which was much less than the optimum moisture content for mycelial growth. For the mass cultivation of mycelia, the hydrated grains with cold water were placed in plastic bottles. The mycelial growth ra in e bottled grains was high in the early stage with inoculation of homogenized mycelium. The mycelium activity was maintained by adding sterilized water in the middle of the cultivation period. Jupjang underwent sensory evaluation to examine the possibility of utilizing basidiomycetes in functional foods. The grains fermented with Ganoderma lucidum was the best for Jupjang. The combination of malt soybean and Job's tears was the best for Jupjang. The acceptability of Jupjang was improved during the period of aging time.
