  • The main objectives of this study were to fruit body of Phellinus linteus using liquid spawn. Highest mycelial growth and in vitro fruiting was observed when $180m{\ell}$ of water was added to 200g of brown rice in $1000m{\ell}$ PP bottle. Optimum inoculum amount was 100ml per bottle. Better mycelial growth and fruiting were observed when the amount of brown rice was lowered. For timber log culture of P. linteus, low contamination was observed when logs were sterilized for as low as 60 mins. But, best mycelial growth was observed when the logs were sterilized for 120mins. Among different log types, highest mycelial growth and fruiting were observed in oak and mulberry. Only few fruiting could be observed in birch, chestnut, alder, while no fruiting was produced in Aspen. Best fruiting was produced from isolate PH-211, although other isolates also produced few fruiting.

  • This study examined the dye-properties of natural fabrics dyed with Coptis chinensis and Curcuma longa root fermented with fungi. The optimum culture conditions for the fermentation of microorganisms, the relationship between natural dye color and fermentation conditions were investigated. Two different medical herbs (ground to 80-100 mesh in size) were used as a natural dyeing source. Phellinus linteus (P. linteus), which can grow in different media, such as Agarmedium (only agar containing medium), maltose extract agar (MA) and potato dextrose extract agar (PDA) culture media, were isolated from the medium. P. linteus was confirmed to be the optimum microorganism for the fermentation of Coptis chinensis and Curcuma longa, and the MA medium was confirmed to be the best for culturing. When using the microorganism as the fermenting agent, $32^{\circ}C$ was found to be the optimum fermenting temperature for both natural colorants. Regarding the dyeing property of the fermented natural dye, silk was dyed quite darkly in an appearance by naked eye estimation and the K/S value in the color strength of silk reached a high level of 16 after the fermenting process. The washing fastness of dyed silk after treatment washing was reduced from 4 to under4 and indicates that dyed silk with fermented plant was not unsubstantial. The light fastness was 1 to 2, showing intended to maintain due to the fermentation process.

  • A key molecule in the pathogenesis of Alzheimer's disease (AD) is the ${\beta}$-amyloid peptide ($A{\beta}$) generated by ${\beta}$-secretase activity, an aspartic protease. This study was designed to evaluate inhibitory effect of the high-molecular weight water-soluble polysaccharides (Et-P) isolated and purified from Phellinus linteus fruiting body on ${\beta}$-secretase activity. The Et-P was purified from the hot water extract of Phellinus linteus fruiting body mainly by 75% ethanol precipitation and DEAE-Cellulose column chromatography. From the DEAE-Cellulose chromato-gram and molecular weight analysis, the Et-P was shown to be a mixture of three polysaccharides with molecular mass of 1,629, 1,294, and 21 kDa, respectively. The monosaccharide composition of Et-P was determined to be glu-cose, galactose, and mannose as major sugars, glucose being the most prominent one (48% in mole percentage). The elemental analysis and FT-IR analysis suggested that Et-P is typical polysaccharides having at least partially ${\beta}$-linkages and possible existing as complex with phenolic compounds. The laminarinase digestion and HPAEC-PAD analysis suggested that Et-P is a variant of beta-(1,3)-glucans. The Et-P showed DPPH radical scavenging activity and, especially, a significant inhibitory activity on ${\beta}$-secreatase activity (48% inhibitin at 100 ${\mu}g/mL$), suggesting that they may inhibit the formation of $A{\beta}$ which is the major causative of Alzheimer's disease. The results of this study suggest that the water soluble polysaccharides of Phellinus linteus fruiting body can be a potent material for the development of preventive or therapeutic agents for AD.

  • The extract contents of various Phellinus species (Hymenochaetaceae) including P. linteus, P. baumii, P. pini and P. igniarius of domestic and foreign products, were examined to standardize the quality of these products. The differences of various extract contents were identified and compared between different species of Phellinus products. The thin layer chromatographic patterns were also analyzed and six unidentified samples were thought to originate from P. baumii and P. igniarius. The chemical standardization for the quality control of various origins could be suggested by this study.

  • The effect of hot water and methanol extracts of 9 species from Korean mushrooms (Fomitopsis pinicola, Fomitella traxinea, Codyceps militaris, Phellinus linteus, Coriolus versicolor, Sparassis crispa, Ganoderma lucidum, Fomes fomentarius, Agaricus blazei) on the growth of Helicobacter pylori were examined using a Mueller-Hinton agar diffusion method. Hot water ($121^{\circ}C$) extracts from fruit bodies of F. traxinea, C. militaris, P. linteus, C. versicolor and F. pinicola showed $10{\sim}15\;mm$ inhibition zone against H. pylori. Methanol extracts of F. pinicola showed 44 mm inhibition zone, but another extracts showed no inhibition. Early fractions of DEAE-Sephadex A-25 column chromatography of methanol extracts from F. pinicola showed high inhibition activity against H. pylori.

  • Mycelia of Pleurotus ostreatus, Phellinus linteus, Ganoderma lucidum and Lentinus edodes were cultured in the selected cereals to generate functionally active cereals. The optimum water contents for the mycelial growth were 50%(wt/wt) for brown rice, barley and soybean and 75% for wheat and corn, respectively. P. ostreatus grew well in the most cereals while the mycelial growth of P. linteus, G. lucidum and L. edodes in soybean were siginificantly retarded. The contents of β-glucan and glucosamine in the mycelial cereals were determined. Wheat cultured with mushroom mycelia showed high ß-glucan content. Especially, wheat with G. lucidum contained the highest value of 26.16%. Soybean cultured with G. lucidum showed two-fold increase in glucosamine content with 9.63% of total mass while wheat showed 7.91%. Overall, wheat cultured with G. lucidum was the best functional cereal in terms of β-glucan and glucosamine contents.

  • The purpose of this study was to investigate the effects of p. Linteus and C. militaris supplement on lactate, phosphorous, ammonia, MDA(malondialdehyde), GPX(glutathione peroxidase) and TAS(total antioxidant status) following $VO_{2max}$, and 85% $VO_{2max}$ exercise. The 15 male college students were divided into three groups: 5 P. liteus supplied(PL), 5 C. militaris supplied(CM), and 5 placebos supplied(PB) and compared the differences between supplement before and after. Obtained results were as follows: In the exercise performance time, there were no differences in PL, CM and PB groups. Regular supplement of P. linteus or C. militaris partially reduces fatigue induction factors. Also, P. linteus or C. militaris supplement decreases MDA, increases GPX and TAS. Therefore, it can be concluded that P. linteus or C. militaris supplement not only have a pharmacological effect for clinical treatment, but also have a maintenance effects on the tissue oxidant-antioxidant system after exercise.

  • Although aronia (Aronia melanocarpa (Michx.) Elliott) contains higher levels of polyphenols and more antioxidant activity than other berries, it is a berry that is difficult to eat raw due to its strong astringent taste and lack of sweetness. Therefore, in this study, we investigated the effect of tannin reduction of aronia by bioconversion method using mushroom mycelia cultures. Aronia and liquid cultures of Lentinula edodes and Phellinus linteus mycelia were mixed and then treated for 48 hours at 60℃. Tannin content, total polyphenol, total flavonoid and antioxidant activities (DPPH, ABTS radical-scavenging activities and FRAP activities) were investigated. The tannin content decreased from 64.2 mg ECE/g to 57.9 mg ECE/g (9.8% reduction) when treated with liquid culture of L. edodes and from 77.3 mg ECE/g to 47.9 mg ECE/g (38.1% reduction) from treatment with a liquid culture of P. linteus. Therefore treatment with mushroom mycelia culture solution may improve the palatability of aronia reducing the astringent taste.

  • This study was carried out to obtain the basic data on artificial culture of Phellinus linteus. The optimum condition for the mycelial growth was $25{\sim}30^{\circ}C$ and pH $6.0{\sim}7.0$. The carbon sources such as D-glucose, D-mannose and Dextrose were favorable to mycelial growth. As nitrogen sources, peptone, cassamino acid and glutamic acid appeared to be favorable. The optimum C/N ratio was about 20:1, when 2% of glucose was provided as a carbon source. The better organic acids and vitamin among tested ones were gallic, silicic acids and biotin. The mineral nutrients of $KH_2PO_4,\;FeSO_4{\cdot}7H_2O,\; MgSO_4{\cdot}7H_2O,\;ZnSO_4{\cdot}7H_2O$ were effective and the optimum concentrations were 0.05, 0.001, 0.02 and 0.003%, respectively.
