This study was carried out to investigate the mycelial growth and density of A. auricula treated four kinds of substances L-citrulline, L-carnitine, Senna, Garcinia cambogia made from 10, 100, 500, 1000, 1500, 2000 times solutions respectively. Senna all treatments made from 10, 100, 500, 1000, 1500, 2000 times solutions are available for mycelial growth and density than control. Senna treatment made from 100 times solution of them is the best. L-citrulline treatment made from 500 times solution grew more much 7.86mm for 15 days than control, also it was optimal. L-carnitine treatment made from 100 times solution grew more much 3.4mm for 15 days than control, also it was optimal. Garcinia cambogia all treatments made from 10, 100, 500, 1000, 1500, 2000 times solutions were not available for mycelial growth and density than control. But Garcinia cambogia treatment made from 1000 times solution of them was similar to control. Accordingly, these solutions like that were effective to mycelial growth and density than control.

Mushrooms growing spontaneously in the Juwangsan National Park were surveyed from April to October 2017 for supporting management of higher fungi and creating a bio-diversity database of the park. In total, two divisions, eight classes, 21 orders, 85 families, 225 genera, and 503 species were detected. Among them, 247 species belonged to order Agaricales, which occupied 48.8% of the population, followed by members of orders Polyporales and Russulales. The mushrooms were abundant in August, and an altitude of 300-400 m above sea level was optimal for their growth, such as those found at Sanguijigu, Deajeonsa, and Geodaeri semgoal areas. Furthermore, Macrolepiota procera and Sarcodon aspratus, which belong to criteria of climate change, were detected in this survey.

The acute toxicity of a crude extract of maitake mushroom(Grifola frondosa practical compound: GFPC) and the mixture of maitake mushroom extract and white jelly mushroom extract(Tremella fuciformis practical compound: TFPC). For acute oral toxicity test, male and female ICR mice were randomly assigned to five groups, consisting of 12 animals each, six males and six females, received either GFPC or the mixture of GFPC and TFPC, at dose of 0, 2,000 and 5,000mg/kg b.w. by orally(10ml/kg b.w.). For the period of 48hr, clinical signs, body weight and food intake were measured. All animals survived during the study and did not show any clinical signs. Food intake was mildly decreased in both GFPC and the mixture of GFPC and TFPC treated groups, however, body weight gain showed no significant difference among the groups. It is suggested that LD50 of GFPC and the mixture of GFPC and TFPC by oral administration was estimated to be over 5,000mg/kg in both sexes of mice. These results conform that GFPC and the mixture of GFPC and TFPC are safe and no toxic at average dietary level.

White jelly fungus (Tremella fuciformis Berk) is effective for hypertension, diabetes, obesity, lung disease, beauty, and has been known as an elixir of life in ancient Chinese dynasty. In this study, we investigated the anti-obesity and diabetic effects of the fermented white jelly fungus extract by the bioconversion process. We fed an obesity-inducing mouse with 5% non-fermented Tremella fuciformis (TF), 2.5% fermented Tremella fuciformis (FTF), and 5% FTF containing High Fats Diet (HFD) and HFD for 8 weeks, respectively. The oral glucose tolerance test (OGTT) was performed analysis after 7 weeks of feeding and the dietary intake, food efficiency ratio, body weight, liver, epididymal fat weight, and serum insulin level were measured after 8 weeks of feeding. Also, HOMA-IR was analyzed. The concentrations of serum total cholesterol, triglycerides test was analyzed. The FTF compare with 5% TF and HFD confirmed that 5% FTF reduced body weight, tissue weight, triglycerides concentration, HOMA-IR, respectively. As a result, we confirmed that the fermented white jelly fungus has the anti-obesity effect. Finally, this study can be used a basic data for obesity treatment using fermented white jelly fungus.

Chemical compositions of dried Auricularia polytricha mushroom were analyzed when the dried mushroom were soaked in distilled water at different soaking condition. Physicochemical properties of soaked mushroom were investigated. Compositions of chemical components were 12.6% crude protein, 2.1% crude fat, 6.7% crude fiber and 6.2% ash. The contents of Ca, K, Mg were higher than those of other minerals in the sample, but Mn and Ni were of little quantities. The major amino acids of the sample were found to be aspartic and glutamic acid. The increase in the soaking time and temperature increased the ratio of water uptake, amount of water soluble solid, browning and pH value in the soak water. Ribonucleotide contents of the sample after soaking decreased depending on soaking time and temperature.

To ensure food-safety of mushrooms from radioactive contamination, edible mushroom samples distributed in Gyeonggi province in Korea were collected according to species and country of origin. A total of 284 mushrooms, belonging to 10 species (Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, Agaricus bisporus, Flammulina velutipes, Phellinus linteus, Inonotus Obliquus (Chaga), Auricularia auricula-judae, Ganoderma lucidum and Tricholoma matsutake) were subjected to radioactivity testing. The concentration of artificial radionuclides, 131I, 134Cs, and 137Cs, was analyzed using gamma-ray spectrometry. 131I and 134Cs were not detected more than MDA value from all samples. Among 204 domestic mushrooms, however, 137Cs were detected in 0.21~2.58 Bq/kg from six cases (3 Lentinula edodes, 1 Ganoderma lucidum and 2 Tricholoma matsutake), whereas 137Cs were detected in 0.21~53.79 Bq/kg from 38 cases (22 Inonotus Obliquus(Chaga), 14 Phellinus linteus, 1 Lentinula edodes and 1 Tricholoma matsutake) among 80 imported mushrooms. In addition, average concentration of 137Cs in 10 Chaga mushroom-processed products was more than twice as much as dried Chaga mushroom, and maximum concentration was 123.79 Bq/kg. Results suggest that radioactivity monitoring system for imported mushrooms and mushroom-processed products should be continuously intensified to secure food-safety in Korea.

The effect of 12 edible mushroom species on the antioxidant and cytotoxicity on cancer cells were studied Methanol extract of Lyophyllum ulmarium, Cordyceps militaris and Sarcodon aspratus showed $30\~60\%$ DPPH radical scavenging activity and $39\~53\%$ protective effects against the cytotoxicity of $B_2O_2$. Methanol extracts of Sarcodon aspratus, Lyophyllum ulmarium, Cordyceps militaris, Agaricus blazei and Ganoderma lucidum revealed high inhibitive activities in cytotoxicity on human leukemia tells such as promyelocytic leukemia cell (HL60) and histiocytic lymphoma cell (U937). Highest toxicity was observed against HL60 cells in Sarcodon aspratus methanol extract showing $70.5\%$ inhibition at 1mg/mL whereas Cordyceps militaris methanol extract showed $81.5\%$ inhibition against U937 cells. Most water extracts of edible mushrooms exhibited the lowest effect against HL60 and U937 cells compared to methanol extract. These extract did not show cytotoxic effects against human lymphocyte. Results revealed 5 kinds of edible murshroom (Cordyceps militaris, Agaricus blaxei, Lyophyllum ulmarium, Ganoderma lucidum and Sarcodon aspratus) have strong antioxidative and in vitro anticancer efforts.
