  • To classify fungal species employed for pharmacological effects, mycelial proteins of six isolates of Ganoderma lucidum, five isolates of Schizophyllum commune and five isolates of Cordyceps spp. were separated on polyacrylamide gel to compare them by esterase, acid phosphatase, leucine aminopeptidase and peroxidase patterns. Similarity of isozyme patterns among the isolates of G. lucidum IY003, IY004, IY005 and IY008 was indicated over 70%, but that among the isolates of G. lucidum IY009, IY010 and others was indicated from 48% to 9%. Highest similarity of isozymes of S. commune was observed to be between IY803 and IY805, and similarity between these two isolates was 57%. Similarity among other isolates was shown to be from 40% to 56%. Isozyme patterns of Cordyceps spp. were comparatively different, even though they were originated from the same kind of insect as their isolate. Similarity between Cordyceps spp. IY901 and IY904, which was isolated from moths, was 67% and that of IY905 and IY909, which was originated from the larvae, was 42%. Similarity among other isolates was shown to be from 12% to 67%.

  • Batch kinetics during the exo-polysaccharide (EPS) fermentation of Ganoderma lucidum was investigated as a function of different substrates (glucose and starch), substrate concentration $(1{\sim}7%,\;w/v)$ and subculture (3 times). Logistic model for mycelial growth fitted the experimental data better than Monod and two thirds power model. The Luedeking-Pirt equation was adequate to fit the kinetic data of product formation and substrate consumption. The EPS production was strongly non-growth associated, although it was mixed type. The product formation and sustrate consumption by growth associated mechanism decreased as the concentration of glucose increased, while those of the non-growth associated mechanism increased. However, starch medium increased the growth associated and non-growth associated substrate consumption indicating higher availability of substrate. Also, batch culture in starch medium showed the higher specific growth rate and stability during subculture than those in glucose medium. In conclusion, the enhanced EPS production and stability in the subculture was found to be remarkably improved by use of starch as sole carbon source in medium. The maximum mycelium dry weight and EPS production of 9.463 and 10.410 g/l, respectively, were obtained after shake culture of 7 days at $30^{\circ}C$ from the media containing 7% starch.

  • This study was carried out to compare the medicinal effects of various fruiting body of Ganoderma species and Cordyceps militaris, Phelinus linteus extracts. ${\beta}$-glucan and polyphenol are useful ingredient in mushrooms and they were known to have antioxidant activity. We analyzed ${\beta}$-glucan and polyphenol contents of fruiting body of Ganoderma spp., Cordyceps militaris, and Phellinus linteus. Most Ganoderma spp. exhibited ${\beta}$-glucan contents of 15 to 20%. Cordyceps militalis showed the highest ${\beta}$-glucan level of 25%. Interestingly, eight strains of Ganoderma spp. was analyzed to have higher contents of ${\beta}$-glucan than Phelinus linteus. Polyphenol contents was measured after extraction with different solvents. (D.W., 70% EtOH, 80% MeOH) The level of polyphenol in ASI 7020 strain was at maximum in the water extraction and ASI 7086 showed the highest level in the 70% EtOH extraction. The amounts of polyphenol in strain ASI 7113 was at maximum in the 80% MeOH extraction.

  • Ten strains of 7 species from the genus Ganoderma, G. lucidum ATCC 64251, FP-103561-T, and ES70701, G. applanatum ATCC 44053 and FP-57035-T. G. lobatum ATCC 42985, G. resinaceum ATCC 52416, G. subamboinense var. laevisporum ATCC 52420, G. meredithae ATCC 64492, and G. microsporum ATCC 76024, were studied to discuss their phylogenetic relationships by utilizing restriction fragment length polymorphisms (RFLPs) of mitochondrial DNAs (mtDNAs). Six restriction enzymes, BamHI, BglII, EcoRI, HindIII, PvuII, and XbaI which digested mtDNAs into adequate numbers of restriction fragments for cluster analysis, were used in this study. Restriction profiles of strains for each restriction enzyme were treated as analysis characters to calculate similarity coefficients, which were converted into nucleotide sequence divergence values whose mean values were then arranged in a matrix table. This table was utilized for a phylogenetic analysis using the Neighborjoining method of the PHYLIP package to construct phylogenetic tree. Three strains of G. lucidum and two strains of G. applanatum exhibited different lineages each but one of G. applanatum strains showed a close relationship with G. lobatum, which reflected the species complexity of these species whose strains were phenotypically indistinguishable but genetically distinct. The present results suggest that the natural classification of Ganoderma needs to be considered from the viewpoints of molecular biology-based systematics as well as morphological classifications and cultural identifications for better phylogenetic conclusions.
