Full textAbstract:
Shiitake mushrooms (Lentinus edodes) have many nutritional and medicinal benefits. The cultivation of log-grown shiitake mushrooms encourages forest farming and can be an opportunity for farmers interested in developing an additional enterprise. In 2006, the University of Missouri Center for Agroforestry conducted a nationwide survey of shiitake mushroom producers to analyze the U.S. shiitake mushroom industry by taking into consideration the forces that influence competition based on Porter's five forces model. Shiitake mushrooms are grown primarily as a side business, especially those produced exclusively outdoors. Indoor production on sawdust generates higher income than outdoor production on logs, but log production is more suitable for a small-scale operation in an agroforestry setting. Barriers to entry are created by relationships in the market, economies of scale, and the learning curve effect. Although there are a limited number of spawn suppliers in the market, they produce quality inoculum and maintain good relationships with shiitake mushroom producers. The majority of respondents sell their shiitake mushrooms locally. Gourmet restaurants, farmers markets, and on-farm outlets are the main markets for shiitake mushrooms. Trends in demand are increasing and prices are high. Shiitake mushrooms can be replaced with other common or gourmet mushroom types, but also have their own identity for numerous nutritional and medicinal properties. Competition for log-grown shiitake mushrooms arises from shiitake mushrooms produced on sawdust and from imports. To successfully survive in the market, firms create competitive advantages through quality, customer service, and consistent supply. Barriers to success in the shiitake mushroom business include demanding work requirements, the need for a serious commitment to produce and market shiitake mushrooms, a 1-year time lag between investment and a return on investment, and insufficient production and marketing information. Grower associations, universities, and state and federal agencies must join their efforts to fund and support shiitake mushroom research and industry development.

Reishi (Ganoderma lucidum (Curtis) P. Karst) and shiitake (Lentinula edodes (Berk.) Pegler) mushrooms have high economic value and contain bioactive metabolites that provide heatlh benefits. Shiitake mushrooms have a delightfully unique taste as an edible mushroom. Mushroom production can be increased by utilizing microbes known as MGPB (Mushroom Growth Promoting Bacteria). This study aimed to determine the presence of bacteria associated with shiitake and reishi mushrooms in the baglog and determine how these bacteria influence the growth of shiitake and reishi mycelium. Bacteria was isolated from the mushroom baglog then were purified and centrifuged to obtain the cell-free extract. Furthermore, the bacterial cell-free extracts were poured on PDA media, then shiitake and reishi mycelium were inoculated to test the effect of bacteria isolates on fungal growth. The results showed that three isolates have the potential as MGPB in reishi mushroom, i.e., isolate S1C, S1D, and S2A. Reishi mycelium grown on isolate S2A achieved the fastest maximum growth on day 6th. In shiitake mushroom, it was seen that all isolates showed a negative effect on mycelium growth. Shiitake mycelium in isolate S1C, S1D, S2A, and S2B were seen to form a clear zone on PDA medium.

Mushrooms are appreciated not only for their nutritional value and bioavailability, but also for their medicinal properties. There are a growing number of the studies focused on investigating medical preparation base on natural compounds, including those isolated from a number of fungi species of fungi species. The aim of this study is to compare anti-inflammatory, analgesic and antiulcer effects of extracts of shiitake mushrooms and chanterelle mushrooms in an experiment on rats. Materials and methods. The experiment involved 30 white female rats weighing 170-210 g., divided into 5 groups: group 1 included intact animals; group 2 included animals with modelled pathology; group 3 included animals, which received chanterelle extract; group 4 involved animals, which received shiitake mushroom extract, and group-5 rats received the reference drug. Observation of changes over the inflammatory process in the model of carrageenan-induced inflammation in the paw of the rats revealed an anti-exudative effect of varying intensity that made up 36.84% for the of chanterelle mushroom extract and 15.79% for shiitake mushroom extract. The dynamics of trypsin-induced inflammatory process showed moderate anti-inflammatory activity, 32.02%, during the courses of the therapy with chanterelle mushroom extract. According to the indicator of analgesic effects produced by the studied extracts, the highest indicator was reached by the chanterelle mushroom extract (33.53%) that exceeded the analgesic effect of the shiitake mushroom extract (17.65%). Therapeutic and prophylactic administration of the chanterelle mushroom extract in a dose of 10 mg / kg in the model of aspirin-induced gastric ulcer in rats showed a pronounced anti-ulcer effect which made up 66.7% compared with that by shiitake mushroom extract (33.4%) and the reference drug “Altan” (100%). Conclusion. The obtained data have demonstrated the promise of using the extracts of chanterelle and shiitake mushrooms for the therapeutic and prophylactic purposes.

Full textAbstract:
Particle-induced X-ray emission (PIXE) analysis of Lentinula edodes mushrooms (Shiitake mushrooms) contaminated with radioactive cesium was performed to study relationships between concentrations of alkali elements in the shiitake mushroom samples and their radioactive cesium levels. The shiitake mushrooms were cultivated using radiocontaminated hard wood logs due to the nuclear power plant accident in Fukushima. The significant localization of radioactive cesium was found in the pileus region of the shiitake mushroom from autoradiographic observation. The concentrations of alkali elements in the shiitake sample were measured by PIXE analysis. The PIXE analysis has shown that the concentrations and transfer coefficients of potassium and rubidium in the pileus are much higher than the other parts of the shiitake sample as is the case of radioactive cesium. It is suggested that radioactive cesium is transferred into shiitake mushrooms in a manner similar to potassium and rubidium. The results of this work have shown the possibility to be able to use rubidium as an elemental tracer for radioactive cesium.

Full textAbstract:
The diagnosis of Shiitake flagellate dermatitis is often overlooked due to the rarity of the condition and the commonality of shiitake mushroom consumption. As the popularity of shiitake mushroom rises and is further incorporated into Western diets, there will be a greater chance of coming across shiitake flagellate dermatitis. In this report, we present a middle-aged female patient who developed shiitake flagellate dermatitis following the consumption of shiitake mushrooms. The physical examination showed characteristic erythematous linear papules in a flagellate like pattern across her neck, abdomen, and thighs. Biopsies demonstrated perivascular, lymphocytic infiltrates with scarce eosinophils. Awareness and familiarity to this condition may aid in addressing patient’s worries and preventing unnecessary procedures or treatments which may exacerbate symptoms.

Full textAbstract:
Influence of shiitake mushroom Lentinula edodes on reproduction of Drosophila melanogaster Shiitake mushroom Lentinula edodes is an edible basidiomycete cultivated worldwide, with high nutritious value and diverse biological activity. There has been an increase in its use as food supplement. Influence of shiitake mushroom extract on the reproductive function and development in an object fruit fly Drosophila melanogaster is described in this research. Fruit flies were maintained on banana medium with or without supplementation of shiitake mushroom's extract, standardized per amount of crude polysaccharides. Shiitake extract supplement, 0.030% and 0.015% crude polysaccharides per volume, induced a statistically significant increase in total number of pupae and flies, and promoted pupae viability. Adult drosophilae males, which received shiitake extract supplement for seven days, had a statistically significant reduction in copulation latency, while thirty day exposure to extract promoted a statistically higher rate of mated flies. Females showed an increase in number of mated flies and reduction in copulation latency post seven day feeding period and had no significant effect on mating ability and fertility post thirty days. Further studies are planned to identify the biologically active components of shiitake mushroom hot water extract and to characterize their effects on reproductive function.

Full textAbstract:
Edible mushrooms are seen as a way of increasing dietary diversity and achieving food security in Ethiopia. The aim of this study was to develop substrates using locally available agro-industrial by-products and animal manures to enhance the production of Shiitake (Lentinula edodes) mushrooms in Ethiopia. The hypothesis was L. edodes mushroom production on seven different substrates: 100% sugarcane bagasse (S1), 80% sugarcane bagasse, 20% cow dung (S2), horse manure (S3), chicken manure (S4), cottonseed hulls (S5), sugarcane filter cake (S6), and sugarcane trash (S7). Mushroom yield and biological efficiency were significantly affected by substrate type (p < 0.05). A significantly higher yield (434.33 g/500 g of substrate) and biological efficiency (86.83%) were obtained using substrate S4 while lower yield (120.33 g/500 g) and biological efficiency (24.33%) were obtained using substrate S7 than when using other substrates. The largest first flush of mushrooms was obtained on S4, and five flushes were produced on this substrate. S4 also had the highest biological efficiency, the highest nitrogen content, and the lowest C:N. Chicken manure is rich in nitrogen, magnesium, calcium, and potassium, which are crucial for Shiitake mushroom growth. Thus, substrate S4 would be a viable option for cultivating Shiitake mushrooms, particularly in regions where chicken manure is readily available. Substrate S2 also provided high yields and rapid fructification and would be a suitable alternative for Shiitake mushroom cultivation.

Full textAbstract:
Mushrooms have a long history of use as food and medicine. They are rich in various nutrients and bioactive compounds, particularly phenolic compounds. In this study, ten mushroom species were selected, and solvent extraction using 80% ethanol was used to extract phenolic compounds. Total phenolic content (TPC), total flavonoid content (TFC) and total condensed tannin content (TCT) were measured to evaluate phenolic content in different mushroom varieties. In the mushroom varieties tested, brown portobello mushroom had the highest TPC (396.78 ± 3.12 µg GAE/g), white cup mushroom exhibited the highest TFC (275.17 ± 9.40 μg CE/g), and shiitake mushroom presented the highest TCT (13.80 ± 0.21 µg QE/g). Antioxidant capacity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), 2,2′-azino-bis-3ethylbenzothiazoline-6-sulfonic acid (ABTS) and total antioxidant capacity (TAC) assays. The highest DPPH free radical scavenging ability was found in white cup mushroom (730.14 ± 55.06 µg AAE/g), while the greatest iron-reducing ability (FRAP) was recorded for shiitake mushroom (165.32 ± 10.21 μg AAE/g). Additionally, Swiss brown mushroom showed the highest ABTS antioxidant capacity (321.31 ± 5.7 μg AAE/g), and the maximum TAC value was found in shiitake mushroom (24.52 ± 1.2 μg AAE/g). These results highlight that most of the mushroom varieties studied showed high phenolic contents and demonstrated strong antioxidant activity, with shiitake mushrooms standing out due to their high TCT and FRAP values, and the highest TAC value among the varieties studied. In addition, LC-ESI-QTOF-MS/MS was used to characterize the mushroom samples, and tentatively identified a total of 22 phenolic compounds, including 11 flavonoids, 4 lignans, 3 phenolic acids, 2 stilbenes and 2 other phenolic compounds in all mushroom samples. The research results of this study showed that mushrooms are a good source of phenolic compounds with strong antioxidant potential. The results can provide a scientific basis for the development of mushroom extracts in functional food, health products, and other industries.

Full textAbstract:
<p><em></em>Shiitake is an edible mushroom native to East Asia. In the present research, the soaking water was targeted as the vehicle to enrich the substrate. The amount of nutrients in the substrate is severely reduced by mycelium growth and development during spawn running and browning period. Some part of this reduction can be compensated by soaking the substrate in the enriched soaking water. In this study, soaking water was enriched by some complement materials and enrichment effects on some important properties of shiitake mushroom were evaluated. The highest biological efficiency (69.88 %) was gained with soaking the blocks in wheat bran extraction suspension. The highest dry matter of mushroom was obtained by rice bran extraction suspension as the enriched soaking water. The results of this research showed that some important properties of shiitake mushroom can be improved by soaking the blocks with enriched soaking water. According to the results, wheat bran extraction suspension was the best enriched solution to increase productivity of shiitake mushrooms and rice bran extraction suspension was suitable to improve quality of mushrooms.<strong></strong></p>

CAPESO cultivo de cogumelos comestíveis vem ganhando espaço no meio agrícola em todo o país, contribuindo assim com uma nova opção de produto no mercado de alimentos. A atividade está ligada a manejos culturais e artesanais com princípios ambientalmente sustentáveis e gera renda para a pequena propriedade rural. Neste contexto, o presente estudo avaliou as potencialidades do cultivo artesanal do Shiitake como uma atividade para agroecossistemas sustentáveis. Para tanto, foi realizado um resgate do histórico da implantação e evolução do cultivo artesanal do cogumelo Shiitake em propriedades consideradas modelos, localizadas nos municípios de Pato Branco, Guarapuava e São José dos Pinhais no estado do Paraná e Frei Rogério em Santa Catarina. Na sequência, uma análise comparativa entre os sistemas de cultivo das propriedades e o aproveitamento de áreas de fragmentos florestais ou reflorestamento foi conduzido. Foram avaliados também aspectos de produção, renda da atividade e pluralismo do estabelecimento rural, bem como, efetuada uma caracterização dos parâmetros de qualidade nutricional dos cogumelos produzidos nas diferentes propriedades. Os resultados obtidos revelam potencialidades econômicas na produção do Shiitake. A atividade também possui potenciais para o aproveitamento sustentável de áreas de mata nativa e de reflorestamento, contribuindo para a otimização do uso do espaço físico na pequena propriedade. A cultura artesanal do Shiitake interage de forma sistêmica, aproveitando à madeira oriunda do próprio estabelecimento rural, evitando a contaminação através de agroquímicos no produto e no ambiente e auxiliando na renovação da biomassa do agroecossistema. Por fim, ficou constada a elevada qualidade nutricional dos cogumelos produzidos nos diferentes substratos utilizados nas propriedades estudadas. As amostras de Shiitake apresentaram elevados conteúdos de proteínas, fibras, minerais e baixos conteúdos de gordura.
Edible mushroom cultivation has been gaining ground in the agricultural environment throughout the country, creating a new product option in the food market. This activity is linked to cultural and artisanal management with environmentally sustainable principles and generates income for small farms. In this context, the present study evaluated the potential for artisanal cultivation of Shiitake as an activity for sustainable agroecosystems. Initially, the historic of implementation and evolution of artisanal cultivation of Shiitake mushroom on properties considered models in Pato Branco, Guarapuava and São José dos Pinhais (Paraná) and Frei Rogerio, (Santa Catarina) were carried out. Consequently, a comparative analysis between the cultivation systems of these properties and the use of small wooded areas and reforested areas was conducted. Aspects of production, income and pluralism of the farms, were also performed. At the end, the nutritional quality parameters of mushrooms produced in different properties were evaluated. The results show economic potential in Shiitake production. The activity also has potential for the sustainable exploitation of native forest and reforested areas, contributing to the optimal use of physical space small properties. In artisanal cultivation of Shiitake there is a systemic interaction verified by the use of wood from the same farm, assisting in the renewal of biomass of the agroecosystem. Finally, it was found that mushrooms produced on different substrates used in the studied properties have high nutritional quality. Shiitake samples exhibited high contents of protein, fiber, minerals and low fat content.

In Brazil there was little research related to Shiitake axenic culture. It was researched in this experiment the physical, chemical and environmental aspects in relation to different strains of Lentinula edodes. The aim of this research was to understand the substratum effects in the kinetics of the Shiitake mycelium growth. It was used two Shiitake strains and two different base substrate (eucalyptus sawdust and sugar cane bagasse) varying in three proportions of the supplements. The supplements, a blend of rice and wheat brans, were added in the proportion of 0, 10 and 20% of the base substrate. The experiment was composed of six treatments. It was concluded that the mycelium kinetics growth in culture medium followed a mathematical model that were represented by exponential equation. Gamma parameters were directly proportional to the instantaneous growth velocity in area. The mycelium growth kinetics in volume had no effect relation to the strains and substrate and it followed a mathematical model represented by logarithmic equation. Beta, gamma and delta parameters didn't show any correlation with the growth velocity in volume. There were significant differences between the strains and the mycelium growth in the supplemented substrate. The strain L55 was better adapted than L17.

Resumo: A finalidade principal deste trabalho foi reunir subsídios para orientar os processos desecagem, armazenagem e reidratarão do cogumelo Shiitake. A pesquisa foi realizada durante o ano de 2002 no Laboratório de Tecnologia Pós-Colheita/Secagem da Faculdade de Engenharia Agrícola da Universidade Estadual de Campinas e consistiu em duas etapas: secagem e armazenagem por 3 meses. Os fatores estudados foram: na secagem - geometria de corte (Shiitake inteiro e fatiado), temperatura de secagem (50ºC e 70°C), teor de umidade final (5% e 15%); na armazenagem - geometria de corte (Shiitake inteiro e fatiado), teor de umidade inicial (5% e 15%), embalagem (com e sem saco de polipropileno) e tempo de armazenagem (3 meses); na reidratação - tempo de imersão em água (8 tempos), geometria de corte (Shiitake inteiro e fatiado), teor de umidade inicial (5% e 15%) e tempo de armazenagem (3 meses). Os parâmetros de qualidade estudados foram: cor, textura, massa, teor de umidade, capacidade de reidratação. Os parâmetros de secagem estudados foram: cinéticas experimentais de secagem. As cinéticas de secagem mostraram que a secagem ocorreu no período de taxa decrescente e que a secagem dos cogumelos fatiados secos à 70ºC ocorreu em menor tempo que os demais tratamentos. A temperatura de secagem de 70ºC proporcionou menor escurecimento e os resultados do efeito da secagem sobre a textura do cogumelo foram pouco conclusivos. O tempo de armazenagem afetou a qualidade dos cogumelos ocorrendo maior dureza, gomosidade e escurecimento. Entretanto, o uso da embalagem retardou o escurecimento. Cogumelos fatiados armazenados com 15% de umidade inicial e embalados obtiveram pouca variação de mastigabilidade, teor de umidade e massa durante a armazenagem. O tempo de armazenagem provocou redução da capacidade de reidratação para os cogumelos com 5% de umidade inicial. Os cogumelos fatiados, com 5% de umidade inicial e embalados obtiveram valores de reidratação superiores aos demais tratamentos
Abstract: Mushroom (Shiitake), drying, storage and re-hydration: effect on quality parameter process determinations. To orient drying, storage and re-hydration processes, accumulated subsidies by studying some parameters on mushroom Shiitake. During three months, drying, storage and re-hydration processes, were studied on mushroom in 2002 at Drying/Post-harvesting Technology Lab from Agricultural Engineering School of the Campinas State University. In drying process were studied: drying temperature (50º and 70 ºC), final moisture content (5% and 15%), cutting geometry (mushroom whole and sliced); in re-hydration process besides drying temperature and cutting geometry, were assessed also, water immersion (8 times), initial moisture content (5%% and 15%) and storage time (3 months); in packing up process; (with/without polypropylene bag), storage time (3 months) and initial moisture content were evaluated. Color, texture, mass, moisture content, and re-hydration capacity, were also evaluated. Drying kinetics showed that drying occurred at increased rate in the period and sliced mushroom dried at 70º C, occurred in lesser time than other treatments. Drying temperature at 70 ºC had less darkening and the results on mushroom texture drying effects were not conclusive. Drying time affected mushroom quality, occurring great hardness, gummosis and darkening. However, packing up use, delayed the darkening. Stored sliced and wrapped mushrooms with 15% initial moisture content had less, chew property variation, moisture content and mass during storage. Storage time provoked rehydration capacity decrease on mushrooms with 5% of initial moisture. Sliced and wrapped mushrooms, with 5% initial moisture, had re-hydration values greater than other treatments

Full textAbstract:
Produtos naturais são cada vez mais vendidos como suplementos dietéticos devido a várias das suas propriedades terapêuticas, enfatizando a pesquisa para novos medicamentos. Este trabalho mostra que extratos aquosos de Lentinula edodes, Pleurotus sajor-caju e Agaricus blazei exercem atividade citotóxica, através do ensaio da redução do sal de brometo tetrazólio, nas linhagens celulares humanas de carcinoma de laringe (Hep-2) e carcinoma cervical (HeLa). Os extratos foram obtidos inicialmente em três diferentes temperaturas (4C, 22ºC e 50C). Entretanto, a temperatura ambiente foi escolhida para a realização dos outros experimentos já que apresentou os melhores resultados na redução da viabilidade celular. Ensaios bioquímicos realizados em paralelo indicaram uma maior quantidade de polifenóis nos extratos do L. edodes nas três temperaturas de extração e também uma melhor capacidade de eliminação do radical 2,2-difenil-1-picrilhidrazilo. Os resultados para a atividade citotóxica revelaram que o extrato de P. sajor-caju foi mais eficiente do que os extratos de L. edodes e A. blazei, nas linhagens testadas. Modificações morfológicas observadas nas células foram confirmadas pela coloração de Giemsa, após o tratamento com os extratos, sugerindo a inibição da proliferação e indução da apoptose dose/dependente. O tipo de morte celular foi testada com o método da anexina V acoplada a um fluorocromo mais iodeto de propídio, confirmando que tanto os extratos de L. edodes e P. sajor-caju induzem a apoptose tardia. Ensaios da composição química obtidos por cromatografia gasosa acoplada ao espectrômetro de massas mostraram a presença de ácidos graxos nos extratos, com uma prevalência do ácido palmítico no extrato de L. edodes e P. sajorcaju e ácido esteárico no extrato de A. blazei. A quantificação dos carboidratos e proteínas indicaram uma maior quantidade de carboidratos no L. edodes, e o A. blazei apresentou um maior teor de proteínas. Estes resultados indicam que os extratos aquosos dos cogumelos L. edodes, P. sajor-caju e A. Blazei são potenciais fontes antioxidantes, ricos em proteínas e ácidos graxos e possuem atividade anticancerígena por indução da apoptose. No entanto, novos estudos são necessários para explorar seus usos terapêuticos e para elucidar o seu modo de ação no organismo.Submitted by Marcelo Teixeira (mvteixeira@ucs.br) on 2014-06-11T12:32:57Z No. of bitstreams: 1 Dissertacao Tiane Cristine Finimundy.pdf: 150195 bytes, checksum: 16fa4de06cc7be6b6a285105c8c35610 (MD5)

Natural products are increasingly sold as dietary supplements due to several of its therapeutic properties, emphasizing the search for new drugs. This work shows that aqueous extracts of Lentinula edodes, Pleurotus sajor-caju and Agaricus blazei, exert cytotoxic activity by testing the reduction of tetrazolium bromide salt in human cell lines of laryngeal carcinoma (Hep-2) and cervix carcinoma (HeLa). The extracts were obtained initially at three different temperatures (4C, 22ºC and 50C), however ambient temperature was chosen to carry out other experiments that have shown the best results in the reduction of cell viability. Biochemical assays performed in parallel showed an increased amount of polyphenols in the extracts of L. edodes the three extraction temperatures and also a better ability to eliminate the radical 2,2-diphenyl-1- picrylhydrazyl. The results for the cytotoxic activity revealed that the extract of P. sajor-caju was more efficient than that of L. edodes and A. blazei, the strains tested. Observed morphological changes in the cells was confirmed by Giemsa staining after treatment with the extracts, suggesting that the inhibition of proliferation and induction of apoptosis dose/dependent. The type of cell death was assayed by the method of annexin V bound to a fluorochrome and propidium iodide further confirming that both of L. edodes and P. sajor-caju induce apoptosis late. Testing the chemical composition obtained by gas chromatography mass spectrometer showed the presence of fatty acids in the extracts, with a prevalence of palmitic acid in the extract of L. edodes and P. sajor-caju and stearic acid extract of A. blazei. The quantification of carbohydrates and proteins indicated a greater amount of the carbohydrates L. edodes and A. blazei showed a higher protein content. These results indicate that the aqueous extracts of the mushroom L. edodes , P. sajor-caju and A. blazei, are potential sources antioxidants, high in protein and fatty acids and have anticancer activity by induction of apopt sis. However, further studies are needed to explore their therapeutic use and to elucidate its systemic effects.

Full textAbstract:
Lentinula edodes é um cogumelo comestível que possui qualidades nutricionais, terapêuticas e medicinais. Além disso, muitos estudos na área médica têm comprovado que o cogumelo possui efeito antibiótico sobre microrganismos patogênicos ao homem. Na área agrícola, alguns trabalhos realizados com o cogumelo demonstraram possíveis efeitos no controle de fitopatógenos. O presente trabalho teve como objetivo demonstrar a produção de substâncias antimicrobianas por L. edodes ativas sobre Colletotrichum sublineolum, agente causal da antracnose em sorgo, Alternaria solani, responsável pela pinta preta do tomateiro, Xanthomonas axonopodis pv. passiflorae, agente causal da mancha bacteriana em maracujazeiro e Tobacco mosaic virus (TMV), causador de mosaico foliar em fumo. Para os testes com C. sublineolum e A. solani foram utilizados extratos aquosos de L. edodes, obtidos a partir de basidiocarpos desidratados em pó, dos isolados LE JAB-K, LE 96/22, LE 96/17 e LE 95/01. Os resultados evidenciaram que o extrato aquoso de basidiocarpos do isolado LE 96/22 inibiu o crescimento micelial in vitro e a formação de apressórios por C. sublineolum. Já os extratos dos isolados LE JAB-K e LE 95/01 apresentaram efeito inibitório na germinação de conídios e na formação de apressórios do patógeno. Em contrapartida, os extratos aquosos de basidiocarpos dos diferentes isolados de L. edodes não apresentaram efeito inibitório na germinação dos conídios e no crescimento micelial de A. solani. Por sua vez, os extratos aquosos de basidiocarpos a 20% (v/v) e o filtrado do crescimento micelial de L. edodes, misturados à suspensão de X. axonopodis pv. passiflorae, exibiram redução na multiplicação bacteriana. Todos os extratos aquosos de basidiocarpos dos diferentes isolados testados na multiplicação da bactéria mostraram-se termolábeis, quando autoclavados a 121 °C por 20 min. Em experimentos com plantas de fumo, os extratos aquosos de basidiocarpos dos isolados LE 96/17 e LE 96/22 adicionados à suspensão contendo partículas do TMV reduziram significativamente a ocorrência de lesões locais nas folhas. O extrato aquoso do isolado LE 96/22 apresentou compostos antivirais de natureza termoestável. Finalmente, o extrato aquoso de basidiocarpos do isolado LE 96/22, o qual apresentou a maior atividade antimicrobiana, foi purificado parcialmente por cromatografia de troca aniônica (CTA). O pico V apresentou efeito inibitório no crescimento micelial de C. sublineolum. Por sua vez, a multiplicação de X. axonopodis pv. passiflorae foi inibida pelos picos IV, V e VII. Já os picos I, II e III, obtidos em CTA por gradiente linear de NaCl e o pico I obtido em CTA pelo método step wise, reduziram significativamente a infectividade do TMV em plantas de fumo. Com base nesses resultados, evidencia-se a ação de preparações de L. edodes sobre fitopatógenos, o que demonstra o uso potencial do mesmo no controle de agentes causais de doenças infecciosas em plantas.Lentinula edodes is an edible mushroom that has nutritious, therapeutical and medicinal qualities. Moreover, many studies in the medical area have shown that the mushroom exhibits antibiotic effects on pathogenic microorganism to the man. In the agricultural area, work carried out with the mushroom has demonstrated its possible effects to control phytopathogens. The objective of the present work was to demonstrate the productionof antimicrobial substances of L. edodes active on Colletotrichum sublineolum, causal agent of anthracnose in sorghum, Alternaria solani, responsible for the black spot of the tomato plants, X. axonopodis pv. passiflorae, causal agent of the bacterial spot in passion fruit plants and on Tobacco mosaic virus, causal agent of the mosaic in tobacco plants. For the test with C. sublineolum and A. solani aqueous extracts were obtained from dehydrated fruiting bodies from the shiitake isolates LE JAB-K, LE 96/22, LE 96/17 and LE 95/01. The results showed that the fruiting body aqueous extract from isolate LE 96/22 inhibited micelial growth and appressorium formation by C. sublineolum. The aqueous extracts of isolates LE JAB-K and LE 95/01 exhibited inhibitory effect on conidium germination and on formation of appressorium by the patogen. On the other hand, the extracts of the different isolates of L. edodes did not exhibit inhibitory effect on conidium germination and micelial growth of A. solani. The aqueous extracts of fruiting bodies at 20% (v/v) concentration and filtrate of the micelial growth of L. edodes, when mixed to the suspension of X. axonopodis pv. passiflorae, exhibited decreased on bacterial multiplication. All the aqueous extracts of fruiting bodies tested from the different isolates in the bacterial multiplication were thermobile, when heated at 121 °C for 20 min. In experiments with tobacco plants, the aqueous extracts of fruiting bodies of isolates LE 96/17 and LE 96/22 when added to the suspension of TMV reduced the amount of local lesions on the leaves. When the aqueous extracts of LE 96/22 were heated the antiviral nature was not lost. Finally, the aqueous extract of fruiting bodies from isolate LE 96/22 that presented major antimicrobial activity was partially purified by anion exchange chromatography (AEC). The peak V exhibited inhibitory effect on micelial growth of C. sublineolum. Multiplication of X. axonopodis pv. passiflorae was inhibited by peaks IV, V and VII. Regarding TMV infectivity, peaks I, II and III, obtained in CTA through linear gradient of NaCl, and peak I also obtained through CTA by the method "step wise", significantly reduced virus infectivity in tobacco plants. Based upon these results, it is shown that preparations of L. edodes can interfere whith phytopathogen multiplication, demonstrating its potential to control plant diseases.

Full textAbstract:
AbstractWith the long-term goal of resuming the use of contaminated deciduous broad-leaved forests, which previously provided bed logs for the cultivation of shiitake mushroom (Lentinula edodes), we are developing a method for estimating the radiocesium (137Cs) activity concentration in the trunks of coppiced konara oaks (Quercus serrata) by using current-year branch in the dormant stage. In this study, we examined whether leaves could be used instead of current-year branches in the dormant stage. Our assessment revealed that the leaves obtained at the phenologically stable stage (from the end of the flushing stage to prior to the defoliation stage) can be used to estimate the 137Cs activity concentration of current-year branches (in the dormant stage) by multiplying the leaf 137Cs activity concentration by 0.54 ± 0.03. This result suggests that leaves collected at this stage are suitable for the estimation of 137Cs activity concentration in the trunk. Given that the leaves are more easily to sample than the current-year branches, we propose that 137Cs activity concentration in the trunk of coppiced konara oak can be estimated more easily with this method using leaves.

Full textAbstract:
In the present study, a heat pump dryer was designed and constructed. The performance of a heat pump assisted dryer was studied. The system was operated by using R22. The experimental data of the drying rates of shiitake mushroom was used to predict the specific moisture extraction rates (SMER). The maximum coefficient of performance (COP) of heat pump was also specified. The optimum operating condition was determined by the percentage of air recirculation from the total air mass flow rate. Finally, the key parameter that influence on the performance of the system and drying rate were specified.
