Mushroom Species

Mushroom cultivation in South Korea is increasing fast last decades. Mushroom cultivation of South Korea is 173577 tones and South Korea gains 800 million dollars income annually. Different kind of mushroom species are cultivated and 31% enoki mushroom (Flammulina velutipes), 26% king oyster (Pleurotus eryngii), 26% oyster mushroom (Pleurotus ostreatus), 13% white buton mushroom (Agaricus bisporus) and 4% rest of the total mushroom Lentinula edodes, Ganoderma lucidum, Phellinus vb. are produced in Korea. 764 ha mushroom growing area was used for mushroom cultivation. 31% of total growing area is oyster mushroom (Pleurotus ostreatus) and 14% king oyster (Pleurotus eryngii), 6% winter mushroom (Flummulina velutipes), 16% white button mushroom (Agaricus bisporus), 3% Phellinus, 3% reishii (Ganoderma lucidum) and 27% other mushrooms. Mushroom is consumed frequently in Korea and mushroom consumption per person is 4.2 kg. Growing on log culture (oak mushroom, reishi and Phellinus), growing on shelves (Agaricus bisporus and Pleurotus ostreatus) and bottle culture (Flummulina velutipes, Pleurotus ostreatus, Pleurotus eryngii) are commonly used growing systems.

Button Mushrooms

The study was conducted to analyze the comparative economics of oyster (Pleurotus ostreatus P.) and button mushrooms (Agaricus bisporus J.) in Kathmandu district of Nepal during the year 2012 with the objective to compare their resource productivity. Primary data were collected from semi-structured pretested questionnaire from purposively selected 45 growers from each category. The examination of resource use efficiency showed that most of the resources were not used efficiently and there is further scope of commercialization. It is imperative to banks for investment in mushroom. Study revealed materials are to be decreased in case of oyster mushroom and labor use is to be increased in button mushroom. It is suggested to cultivate button mushroom instead of oyster as button mushroom has increasing return to scale. It was concluded that the mushroom farming was highly profitable and suggested to cultivate button mushroom in long run and oyster mushroom in short run.

Shape And Size

The formation of physogastry of the mushroom mite Dolichocybe perniciosa (Acari: Prostigmata: Dolichocybidae) has not been well understood. The shape and size of this mite vary dramatically. To evaluate the effects of environmental factors on the formation of physogastry we tested eight species of edible fungi hyphae, five temperatures and five humidity levels on the shape and size of physogastry. Dolichocybe perniciosa only fed on six species of edible fungi, Agaricus bisporus, Auricularia auricula-judae, Auricularia polytricha, Flammulina velutipes, Ganoderma lucidum and Lentinula edodes but failed to develop on the hyphae of Pleurotus geesteranus and Pleurotus eryngii. However, the six species of edible fungi had different effects on the formation and development of physogastry in D. perniciosa. The suitable temperature for the physogastric formation was from 18°C to 28°C at 75±5% RH, and the suitable humidity was from 22% to 92% at 25°C. The width of physogastries was less than 0.85 mm at five temperatures. The majority of physogastries were oblong or cylindrical under ideal temperature (25°C), but globular at a low temperature (13°C). The largest length and the highest length/width ratio were recorded at 25°C. The length and width of the physogastry were less than 4.0 mm and 0.8 mm, respectively, under tested humidity levels. The highest length/width ratio was 8.19 at 65% RH.

Active Substances

Although the button mushroom (Agaricus bisporus) accounts for slightly over half of total world mushroom production, specialty mushrooms, e.g., shiitake (Lentinula edodes), straw (Volvariella volvacea), oyster (Pleurotus spp.), and enokitake (Flammulina velutipes), are increasing in popularity. These species contain moderate quantities of good quality protein and are good sources of dietary fiber, vitamin C, B vitamins, and minerals. Lipid levels are low, but unsaturated to saturated fatty acid ratios are high (about 2.0 – 4.5:1). Some species (e.g., shiitake) accumulate cadmium and selenium and other heavy metals, and some may contain toxic substances such as the heat labile cardiotoxic proteins volvatoxin in the straw mushroom and flammutoxin in enokitake. Extensive clinical studies, primarily in Japan, have clearly demonstrated that a number of species have medicinal and therapeutic value, by injection or oral administration, in the prevention/treatment of cancer, viral diseases (influenza, polio), hypercholesterolemia, blood platelet aggregation, and hypertension. Most of the studies have focused on shiitake, enokitake, Pleurotus spp., and on the generally nonculinary Ganoderma spp. Many of the active substances which include polysaccharides (e.g., β-glucans), nucleic acid derivatives (the hypocholesterolemic eritadenine), lipids, peptides, proteins, and glycoproteins, have been isolated and identified. Some of the mechanisms of activity have been elucidated, e.g., antiviral activity via stimulation of interferon production in the host. Additional medical claims less well documented may nonetheless have some validity and merit further study.

The 3 oyster mushroom species namely Pleurotus florida, P. eous, and Hypsizygus ulmarius were evaluated for their biological efficiency (BE) and net returns from the rupee invested (NRRI) in late kharif and rabi seasons. The BE and NRRI of P. florida and H. ulmarius were on par and significantly superior to P. eous in both the seasons. The present study provided corroboration for the suitability of P. florida and H. ulmarius cultivation in the late kharif and rabi seasons whereas, P. eous cultivation in the summer and early kharif seasons. Thus, the season-specific selection of oyster mushroom species promotes the concept of year-round mushroom cultivation.

Abstract This project aimed to study the reinforcement effect of fungal chitin at different loading on chitin/PLA composite. The chitin nanofibers were extracted from three mushroom species (oyster mushroom Pleurotus ostreatus, shiitake mushroom Lentinula edodes, enoki mushroom Flammulina velutipes) and used as a reinforcement element in PLA. The chitin/PLA composite was fabricated using a solvent-casting method followed by the hot-compress molding method. In the solvent-casting method, the chitin nanofibers were dispersed in PLA/chloroform mixture and the mixture was left for solvent evaporation. The solvent-free chitin/PLA thin film was then filled in dog bone mold before proceeded with hot-compress molding at 190°C and 70 bar. The samples with different chitin loading were tested with tensile test to study the mechanical performance of nanocomposite. The chitin/PLA composite from oyster mushroom shows the optimum result (σ= 43 MPa, E= 12 MPa) at 5% chitin loading. The increment of the chitin loading leads to a decrease in both strength and strain. However, for the samples from enoki and shitake mushrooms, the optimum chitin loading is 10% with 55 MPa and 56 MPa tensile strength, respectively. This study suggests the potential of fungal chitin as reinforcement in PLA.

Os sais de lítio são usados no transtorno de humor, uma vez que este elemento químico atua no sistema nervoso central. Para aumentar a biodisponibilidade deste metal, estratégias são estudadas, como a bioacumulação em basidiomicetos. Desta forma, o objetivo deste trabalho foi realizar uma revisão bibliográfica sobre a capacidade de bioacumulação de lítio in vitro por basidiomicetos. Artigos científicos sobre biocumulação, lítio e basidiomicetos publicados nos anos de 1980 a 2020 foram pesquisados. Uma alternativa para o tratamento do transtorno de humor bipolar é o carbonato de lítio, porém sua faixa terapêutica é estreita, o que pode levar a intoxicação medicamentosa. A bioacumulação de lítio in vitro em basidiomicetos pode ajudar na redução dos efeitos colaterais e melhorar a biodisponibilidade do lítio. São escassos os estudos sobre bioacumulação de lítio em basidiomicetos, e a maioria utiliza LiCl como fonte de lítio, provavelmente pela sua alta solubilidade. O cultivo micelial dos fungos em meio líquido têm sido a melhor opção para a produção de biomassa enriquecida com lítio. Dentre os estudos analisados, Pleurotus ostreatus é a espécie mais estudada na bioacumulação de lítio, tanto na forma de basidiocarpo quanto na forma micelial. Outras espécies como Agaricus subrufescens, Ganoderma lucidum, Lentinus crinitus, Pleurotus eryngii também já foram avaliadas. A biomassa micelial bioacumulada com lítio pode ser considerada uma opção de suplementação ao tratamento contra os distúrbios de humor bipolar, ou um preventivo ao suicídio e até mesmo ao Alzheimer, existindo a necessidade de novos estudos.
