  • The genetic relationships among six Cordyceps spp. were investigated based on internal transcribed spacer sequences of ribosomal DNA .A portion of the these genes was amplified by PCR. Approximately 590 base pairs were successfully amplified, cloned, sequenced, compared. The nucleotide sequence of the six amplified fragments were aligned by the clustal W program. As a result, Cordyceps militaris shared 87, 96, 98, 90 and 97% sequences homology with Paecilomyces japonica, Paecilomyces sp. J300, Paeciomyces farinosa. Paecilomyces sp. J500 and Cordyceps sinensis, respectively. Paecilomyces japonica also shared 87, 88, 92 and 87% sequence similarity with Paecilomyces sp. J300, Paecilomyces farinosa, Paecilomyces sp. J500 and Cordyceps sinensis, repectively.

  • This study investigated the quality characteristics of the Seolgiddeok samples prepared with various amounts(0, 0.5, 1.0 and 2.0%) of Paecilomyces japonica powder by examining proximate compositions, color, texture and sensory quality. The composition of the Paecilomyces japonica powder was measured as follows: moisture(7.40%), crude protein(55.77%), crude lipid(7.1l%), and crude ash(5.39%). With increasing Paecilomyces japonica powder content, the moisture and crude protein content of the Seolgiddeok increased; however crude fat and ash contents decreased. In terms of color, the lightness of the Seolgiddeok decreased and yellowness and redness increased with increasing amounts of Paecilomyces japonica powder. Among textural characteristices hardness, cohesiveness, and gumminess were decreased, but springiness increased according to the addition level of Paecilomyces japonica powder. For the sensory evaluation, the overall quality of the SP-l.0% group was not significantly different than the control group(SP group). In conclusion, the optimal addition amount of Paecilomyces japonica powder for Seolgiddeok is proposed as 1% of total weight.

  • The acute toxicity of Paecilomyces sinclairii was tested in beagle dogs. We daily examined clinical signs, body weights, and hematological/biochemical examinations for 14 days after administration of Paecilomyces sinclairii with different dose levels (0, 0.4, 2 and 10 g/kg). There were no clinical signs and no significant changes in hematological and biochemical analysis. These results showed that Paecilomyces sinclairii did not induce any remarkable acute toxic response and the $LD_{50}$ was greater than 10 g/kg in beagle dogs.

  • The purpose of this study is to investigate tile effects of the Paecilomyces japonica on blood glucose in non-insulin dependent diabetes mellitus volunteers. During the 3 months of the experimental period, freeze-dried powder of Paecilomyces japonica (2 g/meal) was given to the subjects right before each meal. Paecilomyces japonica caused a significant decrease of $27.5\%\;and\;35.5\%$ in fasting and postprandial blood glucose levels, respectively. There were significant reductions of $28.5\%\;and\;33.5\%$ in fasting and postprandial blood glucose levels of the male subjects, respectively Paecilomyces japonica also significantly decreased in fasting and postprandial blood glucose levels of $26.1\%\;and\;37.3\%$ in female patients after treatment. This study shows that Paecilomyces japonica supplementation significantly lowered the fasting and postprandial glucose levels in NIDDM patients. These effects presumably contribute to the hypoglycemic activity.

  • The quality characteristics of breads with different concentrations(2%, 4%) of Paecilomyces japonica (J2, J4) and Cordyceps militaris (M2, M4) powder were compared in terms if sensory and mechanical properties. In the sensory test, J2 and M2 groups gained good scores in taste, texture and odor acceptance as control grourp. Paecilomyces japonica-added group showed higher moisture and bigger volume than that of control group, and Cordyceps militaris group showed lower moisture content and decreasing volume. 'L' values of J and M groups was lower than control, and the longer the storage period, the lower the lightness. The more Paecilomyces japonica was added, the higher the 'a' value was, but Cordyceps militaris showed an opposite trend. The hardness of the bread was the lowest in J2 group and the highest in M4 group, and the longer tile storage period. the higher the hardness was (p<.001). Overall, the addition of 2% Paecilomyces japonica showed a similar tendency with control group, and showed good scores especially in acceptance, moisture and volume. Paecilomyces japonica appeared to be more desirable than Cordyceps militaris.

  • The aim of this study was to identify the inhibitory effect of hepatic toxicity and liver lipid metabolism after the administration of Artemisia capillaris and Paecilomyces japonica. SD rats were divided into $CCI_4$ treated group with subgroups of 6% Artemisia capillaries (6A), 4% Artemisia capillaris+2% Paecilomyces japonica (4A2P), 3% Artemisia capillaris+3% Paecilomyces japonica (3A3P), 2% Artemisia capillaris+4% Paecilomyces japonica (2A4P) and 6% Paecilomyces japonica (6P). In this study we also intended to verify the optimum ratio of Artemisia capillaris and Paecilomyces japonica which can reduce hepatotoxicity. Artemisia capillaris and Paecilomyces japonica reduced cholesterol and triglyceride levels which were increased by the treatment of $CCI_4$. HDL-cholesterol level was the most enhanced in the group of 4A2P. On the other hand, athrogenic index (AI) was reduced statistically (p<0.05). When the ratio of Artemisia capillaris and Paecilomyces japonica was 2:1, the improvement of rat serum and liver lipid metabolism and the alleviation of hepatic damage induced by $CCI_4$ were shown to be the most effective in this study. It is considered that the symptoms of severe chemically induced hepatotoxicity could be lessened by Artemisia capillaris and Paecilomyces japonica administration.

  • We describe here the complete nucleotide sequence and the exon-intron structure of the Cu,Zn superoxide dismutase (SOD1) gene of Paecilomyces tenuipes and Paecilomyces sp. The SOD1 gene of P. tenuipes spans 966 bp, and consisted of three introns and four exons coding for 154 amino acid residues. Three unambiguous introns in P. tenuipes separate exons of 13, 332, 97, and 20 bp, all exhibiting exon sizes identical to Cordyceps militaris SOD1 gene. The SOD1 gene of Paecilomyces sp. contains 946 bp and consisted of four introns and five exons coding for 154 amino acid residues. Five exons of Paecilomyces sp. SOD1 are composed of 13, 180, 152, 97, and 20 bp. Interestingly, this result showed that the total length of exons 2 (180 bp) and 3 (152 bp) of Paecilomyces sp. SOD1 is same to exon 2 length (332 bp) of C. militaris SOD1 and P. tenuipes SOD1. The deduced amino acid sequence of the P. tenuipes SOD1 showed $95\%$ identity to C. militaris SOD1 and $78\%$ to Paecilomyces sp. SOD1. Phylogenetic analysis confirmed that the C. militaris SOD1, P. tenuipes SOD1 and Paecilomyces sp. SOD1 are placed together within the ascomycetes group of fungal clade.

  • Distribution and in vitro growth characteristics of entomopathogenic Paecilomyces species were studied based on the specimens and isolates deposited in Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University, Chuncheon, Korea. Paecilomyces species were frequently collected from different mountains and valleys and were almost distributed uniformly. Collection period of Paecilomyces species ranged from July to September, with most of the collections at the end of September. P. tenuipes was mostly collected one among different Paecilomyces species. The optimum medium for mycelial growth of P. tenuipes was PDA, whereas in other media such as SDAY and HMA also produced similar growth. The optimum temperature and pH levels were $25^{\circ}C$ and 6.0~7.0, respectively. Best carbon and nitrogen sources were dextrose and tryptone, respectively, while $KH_2PO_4$ was the best mineral source for mycelial growth. Highest mycelial growth was observed when the C/N ratio was 20:1.

  • For a period of 5 days, the quality of breads with Paecilomyces japonica powder were investigated using chemical, sensory, and mechanical evaluations at $25^{\circ}C$. The result of analysis of chemical properties revealed that the pH value of dough was increased as the amount of Paecilomyces japonica powder increased, but volume of dough and baking loss rate were decreased. Breads with 1% and 2% Paecilomyces japonica powder showed a good overall preference in sensory evaluation. As storing time passed. moisture content, lightness, and redness were decreased in all breads, but yellowness increased. Hardness and gumminess of texture analysis were increased as storing time passed, but springiness decreased. Springiness of the mechanical properties was negatively correlated with pH value of dough and volume of bread, while was positively correlated with volume of dough and baking loss rate. In the analysis of correlation between sensory and mechanical properties showed that hardness of mechanical properties had negative correlation with softness, moistness, and springiness. Cohesiveness of mechanical properties had positive correlation with acceptability.

  • This study was carried to investigate the antidiabetic and lipid metabolism of water extract paecilomyces japonica(PJ) in Streptozotocin (STZ) induced diabetic rats. Diabetes were induced by intravenous injection of STZ at a dose of 42mg/kg dissolved in citrate buffer. The water extract of paecilomyces japonica were orally administrated once a day for 7 days at a dose of 500mg/kg or 1,000mg/kg. The contents of serum glucose, triglyceride(TG), total cholesterol were significantly decreased in PJ treated group compared to the those of STZ-control group. The content of hepatic glycogen and activities of glucose-6-phosphate dehydrogenase(G-6-PDH), glucokinase(GK) were significantly increased, but activity of glucose-6-phoshatase(G-6-Pase) was significantly decreased in PJ treated group compared to the those of STZ-control group. These results indicated that water extract of paecilomyces japonica would have antidiabetic and lipid metabolism effect in STZ-induced diabetic rats.
