  • To produce the functional food materials, 50 kinds of the mycelial extracts from edible mushroom were examined for anticoagulant activity and Phellinus linteus showed the highest activity through the activated partial thromboplastin test (aPTT). The maximum production of anticoagulant activity and the mycelial growth was observed in culture medium containing soluble starch 3.0%, peptone 0.1%, $MgSO_4{\cdot}7H_2O^{\circ}C$ 0.1%, $K_2HPO_4$ 0.1% and in the culture conditions controlled at initial pH 7.0, $30^{\circ}C$ and 150 rpm by the rotary shaker. In addition, the maximum production of mycelial dry weight was 7.5 mg/mL after 10 days under the optimal conditions, and anticoagulant activity was reached to 390 sec in 5 L-jar fermentor.

  • Thailand is one of the largest citrus producers in Southeast Asia. Pathogenic infection by Phytophthora, however, has become one of major impediments to production. This study identified a pathogenic oomycete isolated from rotted roots of pomelo (Citrus maxima) in Thailand as Phytophthora nicotianae by the internal transcribed spacer ribosomal DNA sequence analysis. Then, we examined the in vitro and in vivo effects of Chaetomium globosum, Chaetomium lucknowense, Chaetomium cupreum and their crude extracts as biological control agents in controlling this P. nicotianae strain. Represent as antagonists in biculture test, the tested Chaetomium species inhibited mycelial growth by 50~56% and parasitized the hyphae, resulting in degradation of P. nicotianae mycelia after 30 days. The crude extracts of these Chaetomium species exhibited antifungal activities against mycelial growth of P. nicotianae, with effective doses of $2.6{\sim}101.4{\mu}g/mL$. Under greenhouse conditions, application of spores and methanol extracts of these Chaetomium species to pomelo seedlings inoculated with P. nicotianae reduced root rot by 66~71% and increased plant weight by 72~85% compared to that in the control. The method of application of antagonistic spores to control the disease was simple and economical, and it may thus be applicable for large-scale, highly effective biological control of this pathogen.

  • Species in the genus Trametes (Basidiomycota, Polyporales) have been used in natural medicine for a long time. Many studies reported that mycelia or fruiting bodies of Trametes spp. exhibited effects of antioxidant, anti-inflammatory, anticancer, and antimicrobial activities. However, comparative analysis in this genus is scarce due to limitation of morphological identification and the sample number. In this study, the 19 strains of seven Trametes species were chosen to generate a five-gene-based phylogeny with the 31 global references. In addition, 39 culture extracts were prepared for 13 strains to test for anticancer and antibacterial activities. Strong anticancer activities were found in several extracts from T. hirsuta and T. suaveolens. Anticancer activities of T. suaveolens, T. cf. junipericola and T. trogii were first described here. The antibacterial ability of T. versicolor and T. hirsuta extracts has been confirmed. The antibacterial activities of T. suaveolens have been reported at the first time in this study. These results suggest an efficient application of the genus Trametes as the drug resources especially for anticancer agents.

  • This study analyzed the physicochemical characteristics of Astragalus membranaceus (AM) fermented with seven different mushroom mycelia. Physicochemical characteristics, such as contents of moisture, pH, total reducing sugars, free sugar, and isoflavonoid, were investigated. The moisture content was increased in most of the samples. The pH values of AM fermented with Phellinus linteus and Flammulina velutipes were increased, while the pH of other samples were similar to that of non-fermented AM. The reducing sugar content was in the range of 211.69~391.74 mg/100 g. The extraction yield using water was higher than that when extracted with 80% ethanol. The free sugar content was increased through fermentation with mushroom mycelia. However, the glucose contents of the 80% ethanol and water extracts were decreased. Finally, the calycosin and formononetin contents in 80% ethanol and water extracts of AM fermented with Phellinus linteus were 2,549.24 mg/g, and 827.66 mg/g for calycosin, and 1,366.69 mg/g and 221.28 mg/g for formononetin, respectively. These results suggest that fermentation with mushroom mycelia could be used to increase the bioactivity of AM. The mycelium-fermented AM might be a valuable source of functional material and edible resource for industry.

  • The transfer of isolated nuclei from Agrocybe aegerita mycelia of wild type into Pleurotus florida protoplasts of auxotroph was induced with polyethylene glycol. The type 1 of nuclear transfer products was spontaneous segregants of both parental morphology of colony. Hyphae of A. aegerita type had clamp connections while that of P. florida type lacked. Type 2 was main products of nuclear transfer which formed true clamp connections. Type 3 was clampless products. They all produced primordia and developed basidiocarps similar to Agrocybe aegerita. A comparison of nuclei transfer products was made using isozyme analyses of alcohol dehydrogenase, esterase, lactate dehydrogenase and peroxidase. Isozyme band patterns of some type 2 strains produced a new band. Band patterns from mycelial extracts of the other strains could be characterized by parental bands.

  • This study was conducted to investigate the effect of mycelia of Lentinus edoes mushroom-cultured Lonicera japonica Thunberg (LLJ) on proliferation of the cancer cell lines (Hep3B, MCF-7 and HeLa), sarcoma 180 (S-180) and antiallergy. In an anti-cancer test using Hep3B (hepatic cancer cell), MCF-7 (breast cancer cell) and HeLa (uterine cancer cell), LLJ extract showed higher antiproliferating effect than that of LJ (Lonicera japonica Thunberg) extract. In an anti-cancer testing using Hep3B cells, LLJ extract showed growth-inhibitory effect of $85.60{\pm}4.66%$ at 3mg/rnL. In an anti-cancer testing using MCF-7 cells, LLJ and LJ extracts showed high antiproliferating effect. LLJ showed the tumor suppressive effect in mice injected with S-180 cells. The growth-inhibitory rates against tumor cells were 61% for LLJ, 37% for LJ. LLJ inhibited histamine release from rat peritoneal mast cells activated by compound 48/80. These results suggest that Lentinus edodes mushroom-cultured herb has an antiproliferating effect against cancer cell lines (Hep3B, MCF-7 and HeLa) and S-180 tumor, and will be beneficial in the treatment of allergic reaction.

  • This study wascarried out to compare the medicinal effects of various Ganoderma species mycelial extracts. Among 6 Ganoderma species mycelial extracts by using 100% MeOH, G. species ASI-7150 showed the highest antioxidant effect. In nitric oxide (NO) production and ${\beta}$-hexosaminidase release inhibition assay, the treatment of G. lucidum ATCC64251 (Taiwan) mycelia extracts most effectively inhibited NO production in LPS-stimulated RAW264.7 cells and ${\beta}$-hexosaminidase release. In addition, the treatment of all 6 Ganoderma species mycelial extracts were not affect on RAW264.7 cell viability. Although this preliminary research has thrown up many questions in need of further investigation, it will serve as a base for further studies of medicinal effects of various Ganoderma species.

  • We have previously found that mycelia culture broth of eight kinds of traditional herbal extracts fermented with Phellinus linteus (previously named as 8-HsPLCB) not only inhibited melanin and tyrosinase activity, but also reduced the contents of melanogenesis-related proteins, including tyrosinase and microphthalmia-associated transcription factor, in 3-isobutyl-1-methylxanthine-stimulated B16F0 melanoma cells. For a further study, the effect of 8-HsPLCB against skin pigmentation in brown guinea pigs with ultraviolet B (UVB)-induced hyperpigmentation was investigated. 8-HsPLCB (3%) and arbutin (2%) as positive controls were applied topically twice daily for 4 weeks to the hyperpigmented areas. 8-HsPLCB showed skin-lightening effect as effective as arbutin, one of the most widely used in whitening cosmetics. Melanin index values as the degree of pigmentation showed a significant reduction week by week post 8-HsPLCB treatment and then substantially reduced by 4 weeks. The degree of depigmentation after 4 weeks of topical application with 8-HsPLCB was 32.2% as compared with before treatment (0 week). Moreover, using Fontana-Masson staining and hematoxylin-eosin staining, 8-HsPLCB reduced melanin pigmentation in the basal layer of the epidermis and epidermal thickness changes exposed to the UV-B irradiation as compared with non-treatment and vehicle treatment. The intensity of the skin-lightening effect of 8-HsPLCB was similar to arbutin. These results suggest that the skin-lightening effect of 8-HsPLCB might be resulted from inhibition of melanin synthesis by tyrosinase in melanocytes. To conclude, 8-HsPLCB treatment showed reduction of the melanin pigment and histological changes induced by UV irradiation in brown guinea pigs.

  • Grifola frondosa has been used as an herbal medicine for the treatment of cancer, diabetes mellitus and high blood pressure. In this study, functional polysaccharide was obtained from Grifola frondosa using four different extraction methods: hot water(HwFP), homogenize(HgFP), acid(AcFP), and alkali(AlFP) extraction methods. The effects of these extracts on KB and HepG2 cell lines were then examined for any anti-cancer activity. Alkaline extraction produced a yield of 0.175% and the total sugar content of the extract was 54.97%. We were able to confirm that the polysaccharide extracts from the mushroom produce an anti-cancer effect. The cytotoxicity of AlFP and AcFP against HepG2 cells were 22.86% and 28.88%, respectively, and the cytotoxicity of AlFP against the KB cell lines was 47.76% at a concentration of 1,000 ${\mu}g/m{\ell}$. Therefore, these results suggest that the optimum method for extracting functional polysaccharides from G. frondosa is the alkali extraction method.
