  • The cultural characteristics and antibacterial activities of Cordyceps militaris and Paecilomyces tenuipes were compared. The mycelial growth was the highest on MCM (Mushroom Complete Medium) for C. militaris and on YMA (Yeast Malt Agar) for P. tenuipes. But the mycelial density on MMM (Mushroom Minimal Medium) was lower than other on media. The optimum mycelial growth was observed at $25^{\circ}C$. C. militaris was low mycelial growth when it was transferred over 5 times generation. The carbon source for the optimum mycelial growth was fructose of monosaccharide, maltose of disaccharide and dextrin of polysaccharide. The calcium nitrate of organonitrogen was found the best mycelial growth on C. militaris, while the sodium nitrate observed to be well for mycelial growth on P. tenuipes. The ammonium tartrate was observed to be the best among the inorganonitrogen used for mycelial growth. Antibacterial activities were found out just C. militaris against Bacillus cereus of Gram (+).

  • The purpose of this study was to investigate the effect of Paecilomyces japonica mycelia(PJM) on pH, titrable acidity and microbiological qualify of Jeungpyun(fermented rice cake). Jeungpyun prepared with $0\~\%$ of PJM stored at $5^{\circ}C\;and\;20^{\circ}C$ for 4 weeks and 7 days respectively. Before fermentation of Jeungpyun dough, viable cells of total bacterial counts(TBC), yeasts and lactic acid bacteria(LAB) were $6.0\~9.8\times10^6,\;5.3\~9.0\times10^6,\;5.4\~8.5\times10^6\;CFU/g$, respectively. During the fermentation of dough, viable cells of TBC, yeasts and LAB increased $0.3\~0.4$ log cycle and pH was decreased whereas acidity increased as the progress of fermentation. Total viable cells in Jeungpyun before storage were $5.0\times10^1\;CFU/g$. During storage of Jeungpyun, TBC, yeasts and LAB of control group increased 2.6, 2.4, 2.1 log cycle at $5^{\circ}C$ and 4.8, 4.6, 4.5 log cycle at $50^{\circ}C$, respectively, when reached at maximum level. Major microflora of Jeungpyun was composed of yeasts and LAB during fermentation of dough and storage at $5^{\circ}C\;and\;20^{\circ}C$. Addition of PJM, inhibited the growth of microorganisms, the changes of PH and titrable acidity of Jeungpyun during storage at both of $5^{\circ}C\;and\;20^{\circ}C$. From these results, the addition of PJM extended the shelf-life of Jeungpyun during storage at $5^{\circ}C\;and\;20^{\circ}C$.

  • This study was carried out to identify the phylogenetic relationship and to know the distribution of the entomopathogenic fungi by comparing the DNA sequences of internal transcribed spacer regions (ITS1 and ITS2) and 5.8S ribosomal DNA (rDNA) repeat unit. The entomopathogenic fungi had their specific sequences in ITS1 and 2 regions depending on species. The comparison of the ITS sequences of standard strains indicated that the sequences ITS1 were more variable than those of ITS2. It seems that Paecilomyces tenuipes, Isaria japonicus and P. japonicus are the same species but called as different names because of very similar sequences, and unidentified Paecilomyces sp. KACC 40220 and KACC 40656 showed identical sequences to P. tenuipes. Thirty six strains of the commercial products of entomopathogenic fungi used in this study were divided into four groups by the phylogenetic analysis based on 5.85 rDNA and ITS regions. We found twenty-three strains were P. tenuipes / japonica, eleven strains were C. militaris, and other two strains were Beauveria bassiana and C. multiaxialis, respectively.

  • The present study examined the lipid lowering and antioxidant activity of Paecilomyces tenuipes. Eight week-old male Sprague-Dawley rats were fed one of the three diets, a reference diet without cholesterol addition (NC), a high fat (17 g/ 100 g)-high cholesterol (1 g/100 g) diet (HC) and a HC diet supplemented with 3% P. tenuipes (PT) for 30 days. Total lipid and total cholesterol were reduced significantly by 33 and 37%, respectively, in the PT diet group compared with controls. A similar reduction was found for low density lipoprotein (LDL) cholesterol levels, while plasma high density lipoprotein (HDL) cholesterol and triglyceride (TG) concentrations were not significantly different among groups. Hepatic total lipid and total cholesterol levels, but not hepatic TG levels, were significantly decreased in the PT group compared to the HC group. The administration of P. tenuipes increased the plasma total antioxidant potential and decreased the levels of lipid peroxidation. These results suggest that P. tenuipes exerts significant health benefits through the modulation of physiological functions including a variety of atherogenic lipid profiles and antioxidants in hypercholesterolemia.

  • The purpose of this research was to investigate the immuno-modulatory effect and anti-carcinogenic property of Cordyceps militaris(CM) and/or Paecilomyces japonicus (PJ). The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of 10 ㎍/ml of CM and/or PJ. B lymphocytes subpopulation in splenocytes were increased both CM and/or PJ administered(p.o. for 7 days)-mice. Thymic T lymphocytes, especially TH cells were significantly increased in CM-administered mice. CM and/or PJ treatment inhibited the cell viability of L 1210 mouse leukemia and HL60 human leukemia cells and induced the apoptosis of L1210 and HL60 cells. In addition, CM and/or PJ increased the hemaggutination(HA) titer against SRBC. These results suggest that CM and/or PJ have an immuno-modulatory action and anti-carcinogenic property.
