  • To find new species of Basidiomycetes in Korea, 15 species were collected in the medicinal plants garden of Sook Myung Women’s University during the period from May to November, 1983. Of them, 11 species were identified and classified into 10 genera and seven families. Among these species, Macrocystidia cucumis(Pers. ex Fr.) Heim and Melanoleuca verrucipes (Fr.) Singer were found to be unrecorded species in Korea. Also their two genera are newly found ones in Korea. They were named 'Bahm Saek Min $B\breve{u}s\breve{u}t$' and 'Hin Bol Lock $B\breve{u}s\breve{u}t$' respectively and their characteristics were here reported.

  • GCP is a novel functional food obtained from the extracts of soybean isoflavone fermented with basidiomycetes mycelia. The enzyme reaction makes GCP containing high concentration of isoflavone aglycons, particularly for genistein and high content of polysaccharides. GCP exerts its anti-tumor activities by anti-angiogenesis and induction of apoptosis in cancer tissues and by enhancement of immune responses in immune system.(omitted)

  • In the course of screening lipid peroxidation inhibitor from basidiomycetes, a mushroom, which was collected at O-Dae mountain in Kangweon- Do, was found to have active compound. The mushroom was identified as Polyzellus multiplex, which belongs to Aphylloporalles Thelephoraceae, on the basis of macroscopic and microscopic characteristics of the fruiting body. The methanol extract of fruiting body was extracted with benzene and ethylacetate, sequentially. By using various kinds of chromatographies, PM1, and PM2 and PM3, were purified from the ethylacetate extract and the benzene extract, respectively. Color reaction and analyses of IR, UV, and NMR spectra indicated that PM1 was a derivative of thelephoric acid, and PM2 and PM3 were linoleic acid and oleic acid, respectively. IC$_{50}$ of PM1 for inhibition of lipid peroxidation was 1.96 ppm and LD$_{50}$ was 500 mg/kg.

  • Taurine is one of the essential amino acids for humans and many of mammals. It is produced and contained in fleshes, shells, plants and algae, but has never been found in fungi. We examined six mushrooms for taurine and detected taurine in five of them. Taurine was determined by an automated amino acid analyzer using ion-exchange chromatography, being eluted between phosphoserine as a distinct peak on the chromatogram. Fruit bodies of Flammulina velutipes contained $83\mu$moles/100g fresh wt. the highest level among them, Agaricus bisporos $65\mu$moles, Lentinus edodes $49\mu$moles, Pleurotus ostreatus $9\mu$moles, and Auricularia auricula-judae $20\mu$moles. Taurine was not detected in Ganoderma lucidum. As far as fungi are concerned, this is the first report of the detection of taurine in Basidiomyces.

  • To treat chromaticity contained in effluents of dyeing wastewater efficiently, potent dye-degrading microorganisms were isolated from influent water, aeration- tank sludge, recycle water and settling-tank sludge located in leather and dyeing treatment plant. Six potent strains were finally isolated and identified as Comamonas testosteroni, Methylobacteriaceae bacterium, Stenotrophomonas sp., Kluyveromyces fragilis, Ascomycetes sp. and Basidiomycetes sp. When Basidiomycetes sp. was inoculated into ME medium containing basal mixed-dyes, 93% of color was removed after 8 days incubation. In the same experiment, the 1:1 mixed culture of Basidiomycetes sp. and photosynthetic bacterium exhibited 88% of color removal; however, it showed better color removal for single-color dyes. The aeration-tank and settling-tank samples revealed higher color removal (95-96%) for black dyes. The settling-tank sample also revealed higher color removal on basal mixed-dyes, which resulted in 90% color removal after 6-h incubation. From the above results, it is expected to achieve a higher color removal using the mixed microorganisms that were isolated from aeration-tank and settling-tank samples.

  • This study was performed to understand the interaction between Ophiostomataceae and basidiomycetes fungi during cultures, and whether the basidiomycetes fungi inhibit the growth and decolorize dark pigments of blue staining fungi. The conjoint cultivation was studied on 2% malt extract agar. The ability of basidial cultures to decolorize dark pigments of ophiostomatoid fungi was the main characteristics estimated during this study. More than half of basidial cultures were characterized by deadlock interaction with blue staining fungi. In the dual cultures, where basidial partners were presented by Agaricus bisporus(64), Laetiporus sulphureus(L01/89), Trametes versicolor(09) and unknown fungus(02), antagonism was found at the phase of primary contact of colonies. Replacement interaction resulted usually in decreasing dark colour of substrate was observed for 11 basidial cultures that were belonging mainly to white-rot fungi. Among them Abortiporus biennis(123), Antrodiella hoehnelii(S28/91), Bjerkandera fumosa (137), and Gleophyllum odoratum(124) were characterized by the absence of deadlock-phase: they began to grow over dark colonies of their partners just after primary contact. Basidiomycetes did not affect strongly the pigments of Ceratocystis spp. and Leptographium sibirica isolates, but completely decolorized colonies of Ophiostoma ips and to a smaller degree Ophiostoma minus. Antrodiella hoehnelii(S28/91), Bjerkandera fumosa(137), Gleophyllum odoratum(124) and Trametes versicolor(B18/91) cultures were found to be the most active in decreasing dark color of blue staining fungi colonies. The cultures were recommended for further development as agents of biopulping of wood chips and bio-control of blue stain in woods.

  • This study examined the changes in the protein and mineral composition of Gryllus bimaculatus fermented with Bacillus substilis and the mycelia of Basidiomycetes. Normal Gryllus bimaculatus (S) and experimental group data obtained after an inoculation of Bacillus substilis (SC) (KACC 19623), Pleurotus eryngii (SP) and Cordyceps millitaris (SC) were compared. The crude protein content of the Gryllus bimaculatus (control) was 75.48%, but it decreased to 64.55, 54.32, and 63.53% after fermentation with SB, SP and SC, respectively (p<0.05). An analysis of the organic elements showed that the contents of the carbon and nitrogen sources were also reduced after fermentation, and the most significant decrease was observed after fermentation with SP. In SDS-PAGE, a 120 kDa and a 48 kDa protein of Gryllus bimaculatus were found. On the other hand, protein bands faded after fermentation with SP and SC, respectively. Moreover, no visible band was observed after fermentation with SB. According to amino acid analysis, the total free amino acid content increased 3.84 and 1.74 times after fermentation with SB and SP, respectively, compared to the corresponding baseline data. In contrast, it decreased by 0.52 times after fermentation with SC. Among the essential amino acids found in crickets fermented with SB, the valine and isoleucine content was 3.57 and 2.64 times higher, respectively, than the recommended daily amount of essential amino acids.

  • Short-preservation of basidiomycetes is generally being conducted in slant tubes containing solid medium based on agar. In this study, we investigated the vitality of 28 species and 76 strains preserved on potato dextrose agar (PDA) at $4^{\circ}C$ for 2~7 years. The survival rates of the fungi were 82%, 86%, 94%, 96%, 94%, and 94% for seven, six, five, four, three, and two years old preservation, respectively. The volume of medium in Lentinula edodes showed decrease after 2 years preserved. The pH of preserved medium was 5.42 in 2007 (two years old), but it became nearly neutral as increasing preservation term.

  • Subculture is the most common method for preservation fungi, but has a disadvantage of accumulation of spontaneous mutations during the repeated subculture. To reduce the subculture frequency, the effect of preservation period at $4^{\circ}C$ in a slant culture was examined on the mycelia growth and lignocellulolytic enzyme activities of various basidiomycetes. Mushrooms, including Stereum ostrea, Coprinellus micaeus, Trametes versicolor, Hypholoma fasciculare, Wolfiporia extensa, Pleurotus pulmonarius, Piptoporus betulinus and Ganoderma applanatum were not affected by the preservation period more than two years, indicating that they can be maintained by subculture every two years. Some other tested fungal strains showed a significant decrease in both viability and enzyme activity when they were maintained for two years, suggesting that they should be subcultured at least once in a year. A little correlation was found between the recovery of mycelial growth and extracellular enzyme activity. In conclusion, mycelial activity and enzyme activity according to storage period is expected to be a way of deciding on subculture times for fungal preservation.
