Mushrooms are considered not only as food but also for source of physiologically beneficial medicines. The culinary-medicinal mushrooms may important role in the prevention of age-associated neurological dysfunctions, including Alzheimer's and Parkinson's diseases. Hericium erinaceus (H. erinaceus), is edible mushrooms, is a parasitic fungus that grows hanging off of logs and trees and well established candidate for brain and nerve health. H. erinaceus contains high amounts of antioxidants, beta-glucan, polysaccharides and a potent catalyst for brain tissue regeneration and helps to improve memory and cognitive functions. Its fruiting bodies and the fungal mycelia exhibit various pharmacological activities, including the enhancement of the immune system, antitumor, hypoglycemic and anti-aging properties. H. erinaceus stimulates the synthesis of Nerve Growth Factor (NGF) which is the primary protein nutrient responsible for enhancing and repairing neurological disorders. Especially hericenones and erinacines isolated from its fruitin body stimulate NGF, synthesis. This fungus is also utilized to regulate blood levels of glucose, triglycerides and cholesterol. H. erinaceus can be considered as useful therapeutic agents in the management and/or treatment of neurodegeneration diseases. However, this review focuses on in vitro, in vivo and clinical trials for neurodegerative disease.

Commonly known as the button mushroom, Agaricus bisporus is one of the most widely cultivated mushroom species of edible fungi. In the breeding of new button mushroom, Seolwon was developed by crossing two homokaryons. Because of the predominantly pseudohomothallic life cycle, only a small percentage of homokaryotic meiospores are produced, which do not fruit. Homokaryotic cultures derived from these types of single spores produce a vegetative mycelium that contain a variable number of genetically identical nuclei per cell. After crossing two homokaryons, hybrids were cultivated on a small scale and on a commercial scale at a farm. The spawn was made by a commercial spawn producer and the spawned compost by a commercial compost producer. Mycelial growth of Seolwon on CDA was better at
when it was compared with that of Seolgang. The mature cap shape of new strain Seolwon is oblate spheroid and the immature cap shape is round to oblate spheroid. The cap diameter was 39.7 mm on average. In comparison with white strain Seolgang, the strain had a yield that was 11% higher. It produced fruiting bodies which had a higher weight on average per fruiting body and were 9.7% firmer with a good shelf life. Days of fruiting body were 1-2 days later than those of Seolgang. The physical characteristics such as springiness, chewiness, adhesiveness, gumminess were better than that of Seolgang.

The primary objective of the present study is the characterization of the somatic hybrids of dikaryon-monokaryon (di-mono) crosses in mushroom breeding. We employed this technique for developing superior strains from Pleurotus ostreatus strains with 48 intraspecific hybrids of 12 combinations between six P. ostreatus strains and one P. florida strain. The results on the experiments of hybridization rate, nuclear DNA patterns, and colors and morphology of fruit-bodies, are presented. In di-mono crosses, somatic hybrids among Pleurotus strains showed 100% of crossability as seen in those between P. ostreatus and P. florida strains indicating that the nuclei of a dikaryon is inferred to be migrated to a recipient. 87.5% of the somatic hybrids among Pleurotus strains were similar to the donor dikaryons, and 12.5% of the somatic hybrids presented DNA patterns of both parents. In 16.6% of di-mono crosses between P. ostreatus and P. florida, the nuclear DNA patterns of all hybrids showed the same or similar patterns compared to the donor dikaryons. 70.9% of the hybrids between P. ostreatus and P. ostreatus were similar to the donor dikaryons and 12.5% of them presented the DNA patterns of both parents. 79.2% of fruiting body morphology of the hybrids among Pleurotus strains were similar to the dikaryons and 20.8% of them were similar to both parents. Interestingly, the morphology of all dikaryons were dissimilar each other. All hybrid strains between dikaryon P. florida and monokaryon P. ostreatus showed the fruiting body of which colors were similar to those of the dikaryon, while the hybrids between dikaryon P. ostreatus and monokaryon P. florida were showed the combined colors of both parents. Therefore, the fruiting body color of P. florida tends to be generally dominant. In conclusion, the present study provides a way to find out and suggest superior hybrid strains using the nuclear DNA patterns of hybrids between Pleurotus strains as well as the characteristics of their fruiting bodies. The advantages of the di-mono crossing are needs to be fully utilized in mushroom breeding because it is an ideal way to develop the superior strains of Pleurotus.

Gloeostereum incarnatum is an edible and medicinal mushroom belongs to Family Cyphellaceae of Polyporales, Basidiomycota. The purpose of this study was to investigate the free radical scavenging, anti-inflammatory, and melanin synthesis inhibitory activities of fruiting bodies of Gloeostereum incarnatum. In the free radical scavenging activities, the mushroom extracts showed good 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and chelating activity on the ferrous ions compared with the positive control, BHT. The mushroom extract suppressed nitric oxide (NO) production in LPS-induced RAW 264.7 macrophage cells in dose dependant manners. Significant reduction of paw edema of rats were observed at 2~6 h after administration with 50 mg/kg of the methanol and hot-water extracts, which were comparable with treatment of 5 mg/kg of indomethacin, the positive control. The melanin synthesis of Melanoma B16/F10 cells treated with
of the methanol and hot water extracts decreased melanin concentration to 50% and 45% compared with the control, arbutin. Therefore, the experimental results showed that methanol and hot-water extracts of Gloeostereum incarnatum fruiting bodies might be used for good sources of anti-inflammatory, free radical scavenging, and skin whitening agents for human health.

In analysis of inorganic components of Miscanthus sinensis Andersson var. sinensist, Phosphate increased with the progress of growing stage. in other way potassium, calcium and magnesium was inclined to decrease. The total nitrogen content in the Miscanthus sinensis Andersson var. sinensist was increased until second age cultivated stage, but in its third year, it was decreased apparently. In other way the total carbon content of Miscanthus sinensis was not changed until second year cultivation. But rapid increasing was happen in its third year cultivation stage. 3 year cultivated Miscanthus sinensis Andersson var. sinensist which has a plentiful carbon source can be used as a good culture media source for the formation of mushroom's fruit body. When rice bran added at the amount of 20% to the keep in 65% moisture Miscanthus sinensis Andersson var. sinensist, the fermentation of culture material was well done and the temperature of
fittest for thermophilic microorganism growth was maintained for 5 days from 5 days after treatment. Rice bran 20% added to the Miscanthus sinensis Andersson var. sinensist was the fittest fermentation culture media for the Pleurotus ostreatus vinyl-bag type cultivation. When Pleurotus ostreatus was cultivated in this culture media, the yield was increased by 60% than whole Miscanthus sinensis Andersson var. sinensist containing culture media. The fermentation Miscanthus sinensis Andersson var. sinensist culture media could be substituted by 20% the sawdust in existing culture media(sawdust 50%+cottonseed bark 30%+cottonseed meal 20%).

This study was conducted to know the optimal supplementary level of spent mushroom substrates (Flammulina velutipes) as an energy source and fermentation period in manufacturing of rye silage. Whole crop rye was harvested at full bloom stage and ensiled with spent mushroom substrates of 20%(S-20), 40%(S-40) and 60%(S-60) as fresh matter basis. Each silage was prepared in plastic buckets included with vinyl bag by three replications and fermented for 3, 6 and 9 weeks, respectively. Moisture contents of whole crop rye at full bloom stage and spent mushroom substrates were 62.3% and 54.3%, respectively, and those of silages was ranged from 58% to 64%. Ether extracts content of silages was significantly (P<0.05) increased in 6 weeks of fermentation period. The pH of silages ranged from 4.46 to 5.05, and fluctuated in the changes by fermentation period beside of decreased with elapsing the period in the S-60. The organic acid content of silages was higher in the order of lactic acid, butyric acid, acetic acid and propionic acid. Lactic acid content was higher when fermented for 6 weeks compared to the other fermentation period. Flieg's score for estimation of silage quality ranged from 63 to 80, and was relatively high level in the S-20 and the S-40 fermented for 6 weeks, and was high level in S-20, and was relatively low level in the silages fermented for 3 week. Hence, we suggest that supplementation of 20% spent mushroom substrates in fresh matter basis and fermentation for 6 weeks are resonable for a good quality of rye silage.
