To develop artificial cultivation and improve some problems such as auto-lysis on commercialization of Coprinus comatus that has been known edible and medicinal mushroom, they were conducted for selection of superior strain, suitable culture methods for mycelial growth and fruiting, and morphological characteristics of fruit body. Strain CM 980301 of Coprinus comatus was selected as a superior strain for artificial cultivation. Wheat grain and rice straw full-grown compost media were most effective for preparation of spawn and artificial cultivation of C. comatus, respectively. Spawn running of Coprinus spp. on the rice straw full-grown compost media required to be 15 days from 24 to $28^{\circ}C$. The casing layer incubation before initiation of fruit body formation, required for 13 days at same temperature for spawn running. And then require $10{\sim}11$ days for initiation and $7{\sim}8$ days for development of fruit body from 20 to $24^{\circ}C$. The fruit body of strain CM 980301 was harvested within a week from initiation of primordium formation. The hardness of pileus and stipe that were harvested in optimal stage showed 102 to 169, and 128 to $182\;g/cm^2$, respectively. Yields of srain CM 980301 from the rice straw full-grown compost media was $37.7kg/3.3m^2$. Weight of individual fruit body was 17.9 g in average.

The effect of Herricium erinaceus on the mutagenicity in salmonella assay and quinone reductase activity in hapalclc7 cells were studied. Antimutagenic as evaluated by Ames test, the extract and fractions of JHerricium erinaceus had no effects on the mutagenicity by themselves. However, methanol extract and fractions from Hericium erinaceus showed strong inhibitory effect on the mutagenesis induced by N-methyl -N'-nitor-N- nitroso-guanidine (MNNG) and benzo(a)pyrene (B(a)P). Among the solvent fractions of methanol extract, the hexane fraction, the chloroform fraction and the ethylacetate fraction exhibited stronger inhibitory activity against MNNG and B(a)P induced mutagenesis than butanol and water fractions. The methanol extract, the extract, the chloroform and the ethylacetate fractions of Hericium erinaceus induced the activity of quinone reductase, an anticarcinogenic marker enzyme, in murine hepalclc7 cells while the others did have little effect on the enzyme activity.

This study aimed to examine the major domestic and foreign regulations related to the production of organic products. The production and consumption of organic products have been expanding due to the increase in consumer demand for safe food, as well as improved certification procedures and industry trends. In case of organic mushrooms, there were 405 certified farms nationwide in 2021, with a cultivation area of 3,886,628 m² and a planned production of 6,011 tons. Jeollanam-do has 221 farms, a cultivation area of 2,923,402 m², and a certification plan for 2,132 tons. Shiitake mushrooms are ranked first with 369 farms, a cultivation area of 3,805,636 m², and a certification plan for 3,576 tons, representing 91% of the farms, 98% of the cultivation area, and 60% of the certification planning.

In this study, we measured antioxidant activity as DPPH radical scavenging and the total polyphenol content of pulverized and lyophilized oak pollens inoculated with fungi to confirm the husk removal effect. The total polyphenol content of oak pollen was highest in lyophilized pollen medium inoculated with Armillaria mellea, and was lowest in pollen inoculated with Lentinula edodes. Total polyphenol content of the lyophilized pollen was higher than that of the refined pollen and the pulverized pollen in oak pollen germinated with A. mellea. The total polyphenol content of the lyophilized oak pollen germinated with A. mellea was 1.4-fold higher than that extracted with water. Measurement of antioxidant activity using the DPPH (2, 2 diphenyl-1-picrylhydrazyl) free radical scavenging method showed that the lyophilized oak pollen germinated with A. mellea had the highest and that germinated with L. edodes was lowest in antioxidant activities. The lyophilized oak pollen germinated with A. mellea was 2 to 4 times higher than that extracted with water in the antioxidant activity of DPPH free radical scavenging. Many germinated cells were formed around pore of acorn pollen inoculated with L. edodes, while those were formed at the end of hyphae derived from oak pollen inoculated with A. mellea.

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.

Worldwide production of mushrooms has been increasing by 10-20% every year. Recently, Pleurotus eryngii and P. nebrodensis have become popular mushroom species for cultivation. In particular, China exceeded 8.7 million tons in 2002, which accounted for 71.5% of total world output. A similar trend was also observed in Korea. Two kinds of mushrooms-Gumji (金芝; Ganoderma) and Seoji-are described in the ancient book 'Samguksagi' (History of the three kingdoms; B.C 57~A.D 668; written by Bu Sik Kim in 1145) during the Korea-dynasty. Many kinds of mushrooms are also described in more than 17 ancient books during the Chosun-dynasty (1392~1910) in Korea. Approximately 200 commercial strains of 38 species of mushrooms were developed and distributed to cultivators. The somatic hybrid variety of oyster mushroom, 'Wonhyeong-neutari,' was developed by protoplast fusion, and distributed to growers in 1989. Further, the production of mushrooms as food was 199,829 metric tons, valued at 850 billion Korean Won (one trillion won if mushroom factory products are included) in 2015. In Korea, the major cultivated species are P. ostreatus, P. eryngii, Flammulina velutipes, Lentinula edodes, Agaricus bisporus, and Ganoderma lucidum, which account for 90% of the total production. Since mushroom export was initiated in 1960, the export and import of mushrooms have increased in Korea. Technology was developed for liquid spawn production, and automatic cultivation systems led to the reduction of production cost, resulting in the increase in mushroom export. However, some species were imported owing to high production costs for effective cultivation methods. In academia, RDA scientists have conducted mushroom genome projects since 1997. One of the main outcomes is the whole genome sequencing of Flammulina velutipes for molecular breeding. With regard to medicinal mushrooms, we have been conducting genome research on Cordyceps and its related species for developing functional foods. There are various kinds of beneficial substances in mushrooms; mushroom products, including pharmaceuticals, tonics, healthy beverages, functional biotransformants, and processed foods have also became available on the market. In addition, compost and feed can likewise be made from mushroom substrates after harvest.

Agaricus blazei Murill is a important medicinal mushroom for a powerful immune system builder and tonic. Currently, it is known about a new disease phenomenon that appears to be occurring on a number of mushroom farms. We described a straightforward approach in which molecular methods was used to survey the presence of potentially endo- and epiphytic bacteria infected with the Agaricus blazei. The 16S rDNA was amplified with universal eubacterial primers directly from pure cultures of Agaricus blazei mycelium and fruit body. The 16S rDNA sequences were almost identical (96 to 97% similarity), and phylogenetic analysis placed them in a single unique rRNA branch belong to the uncultural bacterium phylogroup. PCR detection of uncultural bacterium in the malformed tissues of Agaricus blazei were carried out by using 16S rRNA sequenced specific probe. It was strongly amplified at the malformed pileus region of fruit body and also spore print was impossible.
