  • 주로 고온에서 재배되는 왕송이는 온도제어기를 사용하지 않고 재배할 수 있는 잇점이 있다. 여름철 냉방시설없이 재배할 수 있는 품종을 개발하고자 국내외에서 수집된 왕송이균을 교잡하여 새로운 품종 '백련'을 육성하였다. 백련 왕송이의 균배양온도는 $25^{\circ}C$~$30^{\circ}C$이며 자실체 발생온도와 생육온도 거의 동일하다. 다만 배양완료 후 복토를 해야하기 때문에 2차 균사생장기간이 있어 초발이소요일수가 다소 늦다. 하지만 복토를 하기 때문에 주야간 온도차이에도 버섯발생이 용이하고 습도관리가 쉬워 여름철 재배가 유리하다. 버섯의 모양은 순백색에 전형적인 우산형으로 강한 다발성을 가지며 대가 긴편이다. 특히, 병재배보다는 봉지재배를 할 경우 다발성은 더욱 강해지면 자실체의 크기도 증가한다. 적정배지는 포플라 40%+미송 40%+미강 20%를 혼합한 배지이며 평균수량은 병재배시 101g이나 봉지재배에서는 더욱 증가할 것으로 사료된다.

  • Mushrooms are a recognized component of the human diet, with versatile medicinal properties. Some mushrooms are popular worldwide for their nutritional and therapeutic properties. However, some species are dangerous because they cause toxicity. There are many reports explaining the medicinal and/or toxic effects of these fungal species. Cases of serious human poisoning generally caused by the improper identification of toxic mushroom species are reported every year. Different substances responsible for the fatal signs and symptoms of mushroom toxicity have been identified from various poisonous mushrooms. Toxicity studies of mushroom species have demonstrated that mushroom poisoning can cause adverse effects such as liver failure, bradycardia, chest pain, seizures, gastroenteritis, intestinal fibrosis, renal failure, erythromelalgia, and rhabdomyolysis. Correct categorization and better understanding are essential for the safe and healthy consumption of mushrooms as functional foods as well as for their medicinal use.

  • Mushroom has economic, food and medicinal value to a large proportion of human populace. This study assessed the consumption pattern of mushroom species in Southwestern Nigeria. Non-probability sampling method was used to select 20 Local Government Areas (LGAs) from 3 states and four communities were selected purposively from each LGAs. Snow-ball sampling approach was used in selecting 5 respondents from each community, making a total of 400 respondents. Descriptive statistics was used to describe the socio-economic characteristics of the respondents, to compare the differences between the local (wild) and Exotic (cultivated) mushroom Species and to determine the rate at which mushroom substitute is consumed among the mushroom consumers. Logit regression was used to identify the factors influencing mushroom consumption in the study area. Thirty percent of the respondents were aged 41 to 50 years, with mean age of 49.76 years. About 82% had tertiary education, 17.3% earned above N200,000 monthly and 8.8% spent above N6000 monthly on mushroom. Logit regression showed that age (-3.21), household size (-2.17) and medicinal benefits (-2.17) had significant (p<0.01) negative effects on mushroom consumption. Conclusively, mushroom has wide acceptance among the general populace, good for food and medicine; hence, awareness should be created through agricultural policy on the need for mushroom cultivation and consumption in Nigeria.

  • The effectiveness of three kinds of enzymes (chitinase, ${\beta}$-glucuronidase, and lysing enzyme complex), employed as elicitors to enhance the ${\beta}$-glucan content in the sawdust-based cultivation of cauliflower mushroom (Sparassis latifolia), was examined. The elicitors were applied to the cauliflower mushroom after primordium formation, by spraying the enzyme solutions at three different levels on the sawdust-based medium. Mycelial growth was fully accomplished by the treatments, but the metabolic process during the growth of fruiting bodies was affected. The application of a lysing enzyme resulted in an increase in the ${\beta}$-glucan concentration by up to 31% compared to that of the control. However, the treatment resulted in a decrease in mushroom yield, which necessitated the need to evaluate its economic efficiency. Although we still need to develop a more efficient way for using elicitors to enhance functional metabolites in mushroom cultivation, the results indicate that the elicitation technique can be applied in the cultivation of medicinal/edible mushrooms.

  • (1) Objectives: To discover natural skin-lightening agents, we have evaluated the inhibitory activity of EtOH extracts from 20 medicinal plants against mushroom tyrosinase. (2) Methods: Tyrosinase activity was determined by the dopachrome method using L-tyrosine as the substrates. (3) Results: Of the plant extracts tested, the extracts of 4 plants, Albizzia julibrissin, Curcuma longa, Anethum graveolens and Sophora flavescens, exhibited potent inhibitory activity (> 50%) in mushroom tyrosinase assay. Four plant extract, extracts of Agrimonia pilosa, Paeonia moutan, Magnolia obovata and Eugenia caryophyllata also showed relatively strong inhibitory (> 40%) against mushroom tyrosinase. (4) Conclusion: These active medicinal plants may be useful for the development of skin-whitening agents. Since the active medicinal plants may contain effective tyrosinase inhibitors even more than kojic acid, further study to identify the active constituents from the plants is expected.

  • Background: Hair loss related syndromes are increasing due to environmental pollution and stress. Hair care products are mainly prepared by mixing chemicals and natural extracts, such as those obtained from medicinal plants. The purpose of this study was to investigate the effects of 70% ethanol extracts from the flowers of Calendula officinalis, fruit body of Phellinus linteus, and the whole plant of Houttuynia cordata on the growth of CCD-986 cells, hair follicle dermal papilla cells (HFDPC), and 3T3-L1 cells. Methods and Results: All sample extracts at all concentrations, except for that from P. linteus fruit body at $500{\mu}g/m{\ell}$, were cytotoxic to CCD-986 cells. However, none of the sample extracts were cytotoxic to HFDPC. The lipid differentiation of 3T3-L1 cells regulates hair regeneration via secretion of platelet derived growth factor. The 70% ethanol extract of H. cordata whole plant promoted hair growth. Adipogenesis rate significantly increased in a treatment concentration-dependent manner. Conclusions: These results suggest that 70% ethanol extracts of C. officinalis flower, P. linteus fruit body and H. cordata could be used for the development of hair care products.

  • The purpose of this study was to develop molecular identification method for medical mushrooms and their preparations based on the nucleotide sequences of nuclear large subunit (LSD) rDNA. Four specimens were collected of each of the three representative medicinal mushrooms used in Korea: Ganoderma Incidum, Coriolus versicolor, and Fomes fomentarius. Fungal material used in these experiments included two different mycelial cultures and two different fruiting bodies from wild or cultivated mushrooms. The genomic DNA of mushrooms were extracted and 3 nuclear LSU rDNA fragments were amplified: set 1 for the 1.1-kb DNA fragment in the upstream region, set 2 for the 1.2-kb fragment in the middle, and set 3 for the 1.3-kb fragment downstream. The amplified gene products of nuclear large subunit rDNA from 3 different mushrooms were cloned into E. coli vector and subjected to nucleotide sequence determination. The sequence thus determined revealed that the gene sequences of the same medicinal mushroom species were more than $99.48\%$ homologous, and the consensus sequences of 3 different medicinal mushrooms were more than $97.80\%$ homologous. Restriction analysis revealed no useful restriction sites for 6-bp recognition enzymes for distinguishing the 3 sequences from one another, but some distinctive restriction patterns were recognized by the 4-bp recognition enzymes AccII and HhaI. This analysis was also confirmed by PCR-RFLP experiments on medicinal mushrooms.

  • 밀리타리스 동충하초 추출물은 체내 염증반응을 유도하는 peroxinitrite를 밀리타리스 동충하초 추출물 $128{\mu}g/ml$ 처리로 peroxinitrite를 $60.77{\pm}1.67%$ 저해시켜 뛰어난 저해능을 가지는 것으로 free radical의 생성을 억제하며, Raw 264.7 세포에 LPS $1{\mu}g/ml$을 처리하여 NO 생성이 $3.75{\pm}0.20{\mu}M$까지 증가하였으나 밀리타리스 동충하초 추출물 $32{\mu}g/ml$ 처리군에서 $3.21{\pm}0.10{\mu}M$, $64{\mu}g/ml$ 처리군에서 $3.07{\pm}0.13{\mu}M$로 농도 의존적, 유의적으로 감소 시켰다. 또한, 이로 인해 발현되는 염증 유전자 COX-2의 발현을 유의적으로 저해 한 것을 Western blot으로 확인 하였다. 그러므로, 밀리타리스 동충하초 추출물은 항염증소재로의 가능성이 충분하다고 사료된다.
