  • Fifteen species of wild mushrooms, which are classified as edible, medicinal, poisonous, or unknown types, were analyzed for their free amino acid contents. The average total amino acid content was 1,120.0 mg/kg in the edible type, 1,037.8 mg/kg in the medicinal type, and 1,010.8 mg/kg in the poisonous or unknown type, respectively. The edible type wild mushrooms showed the highest average content of total essential amino acids; conversely, the poisonous or unknown type showed the lowest content. Leucopaxillus giganteus (OK811) showed the highest total amino acid (1,212.4 mg/kg) and essential amino acid (490.2 mg/kg) contents among edible type, while Pycnoporus sanguineus (OK1071) showed the highest total amino acid (1,233.7 mg/kg) and essential amino acid (412.8 mg/kg) contents among the medicinal type. Among the poisonous or unknown type, Hypholoma fasciculare (OK826) showed the highest total amino acid (1,223.4 mg/kg) and essential amino acid (442.8 mg/kg) contents. The amino acid contents of wild mushrooms are fundamental data for the screening of useful genetic resources with nutritionally superior properties.

  • 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.

  • The importance of utilizing biological resources has become magnified and it has been a big issue to share the benefit among nations as Nagoya Protocol began in 2010. This study was conducted to research the diversity and distribution of wild mushrooms, and to survey the traditional mushroom knowledge of the people in Jejudo which is a volcanic island having a distinctive climate and forest environment. The research sites were Dongbaekdongsan, Keuneonggot, Hallasan National Park, Muryeongarioreum, Saryeonisupgil and other important area where mushrooms are growing spontainously in Jejudo. A total of 511 species comprising 2 phylums, 8 classes, 20 orders and 74 genera were identified from 1600 specimens collected from 2006 to 2012. In previous studies, a total of 561 species comprising 69 families and 99 genera were investigated. As a result, a total of 755 species comprising 23 orders, 87 families and 263 genera were documented in Jejudo. In this study, 137 species were newly identified as unrecorded species in Jejudo and 9 species, Amanita gemmata, Tricholoma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Bondarzewia montana, Psilocybe argentipes, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were the first record for Korea. Also, 7 species, Amanita gemmata, Tricoloma aurantiipes, Panellus violaceofulvus, Leucopaxillus septentrionalis, Boedijnopeziza insititia, Sarcoscypha occidentalis for. occidentalis and Morchella patula var. semilibera were known as only growing in Jejudo. The traditional knowledge was collected from visiting and questionnaire survey in 50 villages in Jejudo. A total of 23 mushrooms were found in which 12 species were used for food, 2 species were poisonous, 6 species were medicinal, 2 species were used for folk religion and 3 species were used for play purposes. Macrolepiota procera was the most commonly used as an edible mushroom and Chlorophyllum neomastoidea was the most well known poisonous mushroom. Also, 267 cases of traditional knowledge about using mushrooms as a food and medicine were collected. This study has significance for supplementing previous studies about distribution of wild mushrooms in Jejudo and documenting unrecorded species in Korea. Also, it is valuable by providing important data of traditional knowledge for using mushrooms since old times.

  • Three edible species and one species utilized as drug were selected from wild mushrooms collected from mountains and fields throughout Korea during 1977 to 1979 for artificial cultivation. The media, MES for G. lucidum, MHS for P. rudis and MSES and MHS for P. adipose and Pluteus sp. were selected. The range of optimum pH was 4.0 to 5.0 in citric acid-sodium phosphate dibasic for the tested species. The range of optimum temperature for the mycelial growth of G. lucidum and P. adiposa was 25 to 3$0^{\circ}C$ and 30 to 35$^{\circ}C$ for P. rudis and Pluteus sp. For the moisture content 75 to 80% (w/w) in the substrates, the mycelial growth of most tested species was rapid. As the spawning substrates, poplar sawdust for G. lucidum and Pluteus sp., oak sawdust for P. rudis and wheat for P. adipose were selected, respectively. In this experiment, the fruit bodies of all tested species were appeared. Among them, G. lucidum for medicinal purpose and P. adiposa and Pluteus sp. for sources of new edible mushrooms seems to be possible. However, the sporophores of P. rudis were not adequate as an edible mushroom for the commercial due to the leathery flesh.

  • To reduce the production cost of $Pleurotus$ $ostreatus$, discarded medicinal sludge was collected from oriental medical clinics to develop the $Pleurotus$ $ostreatus$ culture medium. According to the analysis of the proximate composition of the materials used in Korean herb medicine, the crude ash contents of $Carthamus$ $tinctrius$ L stem and $Acanthopanax$ $chiisanensis$ were 11.6% and 10.1% respectively, which were relatively higher than the 9.6% of the control medium, waste cotton. Crude protein was detected in 9.8% of the waste cotton medium, whereas it was detected in 14.9%, 13.9%, 13.4%, and 11.5%, of wild mugwort, $Acanthopanax$ $\underline{chiisanensis}$, medicinal sludge, and $Carthamus$ $tinctrius$ L stem, respectively, which are all higher than the control. The pH of medicinal sludges, wild mugwort, and $Aacanthopanax$ $chiisanenses$ ranged from 5.27 to 5.72, which was similar to the 5.70 pH value of waste cotton. In the case of addition concentration of each Korean herb medicine material influencing mycelial growth of the $Pleurotus$ $ostreatus$, the 9% concentration was more favorable compared to that of 3% and 6%. However, the addition of Korean herb medicine materials did not significantly affect the growth of $P.$ $tolaassi$ and $Trichoderma$ $sp.$ According to a field experiment that added 9% of medicinal sludge into the waste cotton medium, the mycelial growth of mushrooms was facilitated by approximately 2 days, and the mushroom yield was increased by 10~15%. Furthermore, pileus and stipe of the mushrooms were even and superior in quality.

  • The global mushroom industry has grown rapidly in recent years in terms of beneficial effects, market value, and demand. India has a wide range of agro-climatic conditions and is largely an agricultural country with a cultivated area of about 4.37 %, generating about 620 million tons of agro waste annually. Mushroom cultivation not only helps recycle agro wastes, but also fills the nutritional gap prevalent among a large population of India. Recently, government industrial policy and creative innovation has promoted research and other endeavors aiming towards the cultivation of mushrooms. Mushroom cultivation in India was initiated in Solan, in the mid-sixties. Mushroom cultivation has been successful in temperate regions of the Himalayas, the Western Ghats, and the hills of northeast India. Recently, many unemployed people have begun to adopt mushroom cultivation as a means of self-employment. It is high time that Indian mushroom cultivators and consumers became aware of the nutritional and medicinal values of cultivated and wild species of mushrooms. The total mushroom production in India between 2010 and 2017 was approximately 0.13 million tons, accounting for a 4.3% increase in the average growth rate of mushrooms per annum. In particular, the total production of white button mushrooms is the highest, with a share of about 73% of total mushroom production. In this review article, we have analyzed the current scenario of the Indian mushroom industry and its contribution to the economic growth of the country.

  • Ganoderma lucidum (Fr.) Karst (Polyporaceae), belonging to basidiomycota, is one of the most famous medicinal mushrooms. This study was carried out to investigate favorable mycelial growth conditions, such as pH, temperature, growth media, carbon sources and nitrogen sources of Korean strains in G. lucidum. The most suitable temperature for the mycelial growth was obtained at $30^{\circ}C$. In general, optimal temperature range for the mycelial growth was found at $25{\sim}30^{\circ}C$. This Mushroom has a broad pH range ($5{\sim}9$) for its mycelial growth and mostly favorable growth was found at pH 5. Generally, Hamada, Glucose peptone, YM, Mushroom complete and Lilly media were the most suitable for the mycelial growth of G. lucidum. Among 10 different carbon sources, dextrin, galactose and fructose were best but the rest of other carbon sources also facilitated the growth of mycelia. The most suitable nitrogen sources were ammonium acetate, glycine, arginine and calcium nitrate, but to a certain extent, all of the supplemented nitrogen sources also stimulated the mycelial growth.
