Full textAbstract:
Background: Cigarette smoke can trigger oxidative stress. An alternative to overcome the harmful effects of cigarette smoke is through antioxidants. White oyster mushrooms (Pleurotus Ostreatusostreatus or P. ostreatus) are a source of exogenous antioxidants because many contain active compounds for potential antioxidants such as phenol and flavonoid compounds. The purpose of this study was to analyze the effect of ethanolic extract of Pleurotus P.ostreatus on 4-hydroxy-2-nonenal (HNE) and glutathione (GSH), as well as to analyze their correlation in the lung of Wistar male rats exposed to cigarette smoke. Methods: The study was a preclinical experiment conducted on 24 rats divided into four groups. The treatment was carried out for 42 days and antioxidant effects were assessed through levels of HNE and GSH in rat lungs. Groups were divided as follows: I- normal control, II- negative control, III and IV exposed to cigarette smoke for 60 minutes/day. Group III (treatment group) was treated with ethanolic extract of PleurotusP. ostreatus at 250 mg/kg BW rat/day, and group IV (comparison group) was treated with N-acetyl cysteine 600 mg /day. Data analysis used was one-way ANOVA and Kruskal Wallis test, and Spearmen rank correlation coefficient test. Results: The results showed that the group receiving ethanolic extract of PleurotusP. ostreatus had HNE levels of (44,18 ± 2,09 pg/mL) and GSH (0,04 ± 0,00 pg/mL) protein. This extract significantly increased GSH levels and inhibited the increase of HNE levels. Results of GSH (p≤0.01) showed significant results using one-way ANOVA. Conclusions: The ethanolic extract of P. ostreatus can prevent lipid peroxidation and decrease endogenous antioxidant levels in lung cells exposed to cigarette smoke. Ethanolic extract of PleurotusP. ostreatus has good antioxidant potential.

ABSTRACT The worldwide commercial production of the oyster mushroom Pleurotus ostreatus is currently threatened by massive attacks of green mold disease. Using an integrated approach to species recognition comprising analyses of morphological and physiological characters and application of the genealogical concordance of multiple phylogenetic markers (internal transcribed spacer 1 [ITS1] and ITS2 sequences; partial sequences of tef1 and chi18-5), we determined that the causal agents of this disease were two genetically closely related, but phenotypically strongly different, species of Trichoderma, which have been recently described as Trichoderma pleurotum and Trichoderma pleuroticola. They belong to the Harzianum clade of Hypocrea/Trichoderma which also includes Trichoderma aggressivum, the causative agent of green mold disease of Agaricus. Both species have been found on cultivated Pleurotus and its substratum in Europe, Iran, and South Korea, but T. pleuroticola has also been isolated from soil and wood in Canada, the United States, Europe, Iran, and New Zealand. T. pleuroticola displays pachybasium-like morphological characteristics typical of its neighbors in the Harzianum clade, whereas T. pleurotum is characterized by a gliocladium-like conidiophore morphology which is uncharacteristic of the Harzianum clade. Phenotype MicroArrays revealed the generally impaired growth of T. pleurotum on numerous carbon sources readily assimilated by T. pleuroticola and T. aggressivum. In contrast, the Phenotype MicroArray profile of T. pleuroticola is very similar to that of T. aggressivum, which is suggestive of a close genetic relationship. In vitro confrontation reactions with Agaricus bisporus revealed that the antagonistic potential of the two new species against this mushroom is perhaps equal to T. aggressivum. The P. ostreatus confrontation assays showed that T. pleuroticola has the highest affinity to overgrow mushroom mycelium among the green mold species. We conclude that the evolutionary pathway of T. pleuroticola could be in parallel to other saprotrophic and mycoparasitic species from the Harzianum clade and that this species poses the highest infection risk for mushroom farms, whereas T. pleurotum could be specialized for an ecological niche connected to components of Pleurotus substrata in cultivation. A DNA BarCode for identification of these species based on ITS1 and ITS2 sequences has been provided and integrated in the main database for Hypocrea/Trichoderma (www.ISTH.info ).

Different local strains of Oyster mushroom were evaluated using different cellulosic agro-wastes including cotton waste, paddy straw and wheat straw for mycelial growth, spawn running and production efficiency of different strains of Pleurotus ostreatsus. Maximum production efficiency of P. Sajur caju was observed (195.9%) on wheat straw while minimum production efficiency was recorded (132.1%) on paddy straw followed by cotton waste where the production efficiency was 107.9%. P. ostreatus (white strain) showed maximum production efficiency (113.7%) on wheat straw and minimum (88.8%) on cotton waste. While the production efficiency of P. ostreatus (gray strain) was almost same on cotton waste and wheat straw but greater than paddy straw (128.3%). The Overall performance of P. Ostreatus (gray strain) remained best during its cultivation.

Full textAbstract:
The Pleurotus genus can use by-products of agri-food industry as substrates to develop its edible fruiting body. Pleurotus ostreatus, which is the most cultivated specie of Pleurotus, has high nutritional and nutraceutical properties; in particular, it is a source of vitamin D2 and fiber named β-glucans. However, food uses of this mushroom are limited because of the lack of value-added applications.
The overall aim of this PhD thesis was to develop functional ingredients from P. ostreatus biomass.
Specific goals were:
a) development of a food application and production of a powdered ingredient with a target amount of vitamin D2;
b) encapsulation of an oxidizable target using P. ostreatus β-glucans as antioxidant and emulsifying agent.
The results showed that using an adequate concentration of dehydrated and milled P. ostreatus for the development of new food applications could help against the increasing vitamin D2 deficiency among specific groups of populations. To enhance the level of vitamin D2 in P. ostreatus, a combined process of UV irradiation and air-drying was applied, and a new powdered ingredient with a target amount of vitamin D2 was obtained. The kinetics of vitamin D2 degradation in P. ostreatus powder was studied as a function of water activity and temperature to predict its stability during storage. The kinetics data obtained can be used as a starting point to project the best formulation strategy to deliver vitamin D2 with functional foods. Since there is a gap of knowledge about the effect of UV irradiation on mushroom bioactive compounds, the antioxidant and antiglycation activities of Agaricus bisporus and P. ostreatus were investigated and the results pointed out that UV irradiation reduced the antioxidant activity, but not the antiglycation properties.
Two different β-glucan-rich extracts were obtained from P. ostreatus; after characterization, they were used to stabilized oil-in-water emulsions. Their stability was checked through variation of oil droplets size distribution over time, in order to find the best formulations suitable for further encapsulation, which was carried out using spray drying technique. After production, the powders were analyzed for the particle morphology and in terms of oil protection against oxidation. Results showed that P. ostreatus extracts provided good emulsifying properties and it allowed excellent protection of α-tocopherol and polyunsaturated fatty acids against oxidation. The effects of the P. ostreatus extracts was tested during in vitro digestion; samples underwent partial aggregation, but the oil droplets were still fairly stable, and α-tocopherol degradation was slower in presence of β-glucans up to the beginning of intestinal phase. The protection against oxidation was also studied during 15 days of accelerated storage; β-glucans improved the oxidative stability of the powders, compared to common emulsifier with no inherent bioactivity.
In conclusion, it is evident that P. ostreatus and its compounds can be exploited as sustainable food ingredients to deal with the requirements of populations with endemic nutritional deficiencies and to stabilize oxidizable target during encapsulation process, in vitro digestion and storage.

Cultivation of edible mushrooms in the world is becoming increasingly popular. People are increasingly aware of their positive effects and therefore are mushrooms used not only in restaurants but also increasingly in human and veterinary medicine. With their growing, but also associated infestation of cultivated cultures of mushrooms by pests and diseases. The farms are most often appear green mold of the genus Trichoderma which cause considerable losses. When growing oyster mushroom is the biggest problem Trichoderma pleuroti, the cultivation of Agaricus is a Trichoderma aggressivum. Therefore, the research of protection against these fungi and important in recent years, importance.
Presented work studies the tolerance selected strains of Pleurotus ostreatus against Trichoderma pleuroti and different heat treatments of the substrate. In experiments was examined relationship between Pleurotus ostreatus, Trichoderma pleuroti and Bacillus subtilis, as well as various forms of heat treatment of the substrate and its enrichment. The experiments were statistically analyzed using ANOVA.
In the case of a common growth Trichoderma pleuroti and Bacillus subtilis was Trichoderma pleuroti considerably restricted, especially in the case of surface inoculation of Bacillus subtilis. Also in a common growth of Bacillus subtilis and Pleurotus ostreatus, Pleurotus ostreatus growth was limited by surface inoculation of Bacillus subtilis was to restrict the growth of Pleurotus ostreatus pronounced.
In the case of the fermentation substrate and subsequent heat treatment, it was found that the enrichment of the substrate and its subsequent fermentation treatment is not suitable for the growth of mycelia of Pleurotus ostreatus. In case the substrate has been infected Trichoderma pleuroti the most appropriate treatment showed fermentation substrate and subsequent heat treatment at 60 ° C. Adding mingled substrate is not proved crucial for the growth of mycelium Pleurotus ostreatus.

Os cogumelos são definidos como macrofungos que tem papel essencial na decomposição da matéria orgânica. Além de sua função ecológica os cogumelos são apontados como alimentos de valor nutricional e medicinal. Estes fatores têm estimulado a produção e o comércio de cogumelos, sobretudo de Pleurotus ostreatus por sua facilidade de cultivo e alta produtividade. Sob este contexto, são necessárias pesquisas que avaliem os fatores que interferem diretamente na produtividade. Frente ao exposto, o presente trabalho objetivou avaliar e comparar o efeito dos fatores ambientais e nutricionais sobre a produtividade e resposta à indução dos primórdios de duas linhagens de P. ostreatus cultivadas em ambientes protegidos. Os resultados obtidos mostraram que os substratos cultivo apresentaram alta heterogeneidade. A caracterização das diferentes formulações indicaram mudanças sutis sobre a relação C/N do substrato, tendo em vista a C/N sofre diminuição ao final do processo devido à degradação da matéria orgânica. Quanto à produtividade registrou-se diferenças entre linhagens e formulações. A formulação F1, apresentou produtividade de 14,65% e eficiência biológica de 72,58 mediante inoculação da linhagem SB, à diferença do observado na linhagem MB que apresentou produtividade de 17,40% e eficiência biológica de 86,20%. Diferenças foram também registradas na formulação B, na qual obteve-se produtividade de 13,79% e eficiência biológica de 79,91% referente a linhagem SB e produtividade de 13,42% e eficiência biológica de 41,39% referente a linhagem MB. Após a colheita, análises bromatológicas foram realizadas com o substrato exaurido. Os resultados revelaram teores de proteína total de 6,82%, 34,13% de cinzas, 1,41% de lipídeos totais e 84,12% de umidade, para a formulação A e 5,73% de proteína total, 22,93% de cinzas, 2,53% de lipídeos totais e 71,85% de umidade para formulação B. Concluiu-se que a satisfatória produtividade de P. ostreatus está diretamente ligada a qualidade de substrato. Para tanto deve-se estabelecer e parâmetros de qualidade no preparo do composto. Quanto ao substrato exaurido sua composição nutricional avaliada indicou a possibilidade de sua utilização em formulações de ração para ruminantes como fonte de proteína de qualidade.
The mushrooms are defined as Macrofungi that play an essential role in the decomposition of organic matter. Besides to their ecological function, mushrooms are well-known to have nutritional and medicinal value as foods. These factors have been boosting the outputs and trading of mushrooms, especially, Pleurotus ostreatus, due to its facility of cultivation and high productivity. In this context, research is needed in order to evaluate the factors that can directly interfere in their productivity. In face to this issue, this work aimed to evaluate and to compare the effects of environmental and nutritional factors in their productivity. In addition, to assess the responses of the induction of the primordial two strains of P. ostreatus cultivated in protected environments. The obtained results showed that the growing substrates displayed high heterogeneity. The characterization of different formulations showed subtle changes regarded to the substrate C/N, knowing that the C/N suffer a decrease at the end of the process due to the degradation of organic matter. There were registered productivity differences among strains and formulations. The formulation A showed 14.65% of productivity and 72.58% of biological efficiency by inoculation of the SB strain. Differently, the strain MB showed 17.40% of productivity and 86.20% of biological efficiency. Differences were noticed in the strain B as well, in which the productivity was 13.79% and biological efficiency was 79.91% regarded to SB strain and productivity of 13.42% and biological efficiency of 41.39% regarded to MB. After the harvest, bromatological analyzes were made with the depleted substrate. The results showed contents of 6.82% of total protein, 34.12% of ashes, 1.41% of total lipids and 84.12% of humidity to the formulation A and 5.37% of total protein, 22.93% of ashes, 2.53% of total lipids and 71.85% of humidity to the formulation B. In conclusion, the satisfactory productivity of P. ostreatus is straightforward related to the quality of the substrate. Therefore, quality parameters should be established to the preparation of the compost. The evaluated nutritional composition of the depleted substrate pointed out the possibility to be used as an item in the formulation of ruminant feed as a high quality source protein.

Abstract: The mushrooms are defined as Macrofungi that play an essential role in the decomposition of organic matter. Besides to their ecological function, mushrooms are well-known to have nutritional and medicinal value as foods. These factors have been boosting the outputs and trading of mushrooms, especially, Pleurotus ostreatus, due to its facility of cultivation and high productivity. In this context, research is needed in order to evaluate the factors that can directly interfere in their productivity. In face to this issue, this work aimed to evaluate and to compare the effects of environmental and nutritional factors in their productivity. In addition, to assess the responses of the induction of the primordial two strains of P. ostreatus cultivated in protected environments. The obtained results showed that the growing substrates displayed high heterogeneity. The characterization of different formulations showed subtle changes regarded to the substrate C/N, knowing that the C/N suffer a decrease at the end of the process due to the degradation of organic matter. There were registered productivity differences among strains and formulations. The formulation A showed 14.65% of productivity and 72.58% of biological efficiency by inoculation of the SB strain. Differently, the strain MB showed 17.40% of productivity and 86.20% of biological efficiency. Differences were noticed in the strain B as well, in which the productivity was 13.79% and biological efficiency was 79.91% regarded to SB strain and productivity of 13.42% and biological efficiency of 41.39% regarded to MB. After the harvest, bromatological analyzes were made with the depleted substrate. The results showed contents of 6.82% of total protein, 34.12% of ashes, 1.41% of total lipids and 84.12% of humidity to the formulation A and 5.37% of total protein, 22.93% of ashes, 2.53% of total lipids and 71.85% of humidity ...

Resumo: Os cogumelos são uma alternativa muito viável na transformação de materiais lignocelulolíticos em produtos uteis, resultam na geração de alimento rico em proteínas, fibras, sais minerais, vitaminas, com baixo teor de lipídeos e carboidratos. Para a produção do cogumelo é necessário obter a Spawn, que pode ser feito a partir de um fragmento ou pseudotecido retirado do seu píleo. Para a fungicultura a fase laboratorial é tão importante quanto à fase no campo. O cultivo de cogumelos gera uma grande quantidade de composto pós-cultivo (SMC - "spent mushroom compost"). O presente trabalho buscou avaliar a influência da maturidade da Spawn na produtividade do cogumelo Pleurotus ostreatus utilizando tempos distintos de maturação. Após o cultivo do fungo foi testado o substrato exaurido na produção de mudas de alface, que foram levadas a campo para avaliar produtividade e análise bioquímica. Para a avaliação da Spawn foram utilizados sete sacos de 2 Kg de composto inoculado a cada três dias, onde a primeira inoculação ocorreu no 13º dia de maturação da Spawn e a ultima no 25º dia. Foram avaliados número de cachos, número de cogumelos, peso dos cachos, massa média de cachos e cogumelos e produtividade. Os maiores valores de produtividade foram obtidos pela 2ª e 3ª inoculação com 19,0 e 19,7 %, respectivamente, com 16 e 19 dias de maturação da Spawn, apresentando uma curva muito semelhante a de crescimento microbiano em geral, em fase Log. A primeira inoculação foi a menos produtiva, e ... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Mushrooms are a very viable alternative in the transformation of lignocellulolytic materials into useful products, resulting in the generation of food rich in proteins, fibers, minerals, vitamins, low in lipids and carbohydrates. For the production of the mushroom it is necessary to obtain the inoculum, which may be made from a fragment or pseudotecido taken from the colonus thereof. For fungicide the laboratory phase is as important as the phase in the field. Mushroom cultivation generates a large amount of spent mushroom compost (SMC). The present work aimed to evaluate the influence of the inoculum maturity on the productivity of the Pleurotus ostreatus mushroom using distinct maturation times. After the fungus was cultivated the exhausted substrate was tested in the production of lettuce seedlings, which were taken to field to evaluate productivity and biochemical analysis. For the evaluation of the Spawn, seven bags of 2 kg of inoculated substrate were used every three days, where the first inoculation occurred on the 13th day of mycelial run and the last on the 25th day. Number of bunches, number of mushrooms, weight of bunches, average mass of bunches and mushrooms were evaluated as a parameter for evaluation of productivity. The highest values of productivity were obtained by the 2nd and 3rd inoculation with 19.0 and 19.7%, with 16 and 19 days of seed maturation. It is concluded that the time of maturation of the inoculum influences the yield of the mushroom Pleurotus ostreatus, showing that the production of the inoculum is a primordial phase to reach high yields. Then, the residue of the Pleurotus ostreatus production was used for the cultivation of lettuce (Lactuca sativa L.) seedlings at doses of depleted compound (50%, 30% and 10%) mixed with the commercial substrate Carolina soil®. For comparison, a control with 100% commercial substrate was used. Seed productivity parameters were ...

Resumo: Pleurotus ostreatus (shimeji) está entre os três cogumelos comestíveis mais consumidos no Brasil e no mundo. Dentre os fatores relacionados à sua produtividade elevada, a mais relevante é a produção do spawn. Spawn é a primeira etapa no cultivo de cogumelos e inicia-se com o crescimento micelial in vitro em meios de cultura, chamado de matriz primária, posteriormente transferida para substrato sólido nomeada como matriz secundária, e então utilizado como inóculo para produção de cogumelos. O objetivo desse estudo foi avaliar a influência dos diferentes processos de preparo do spawn sob efeito na eficiência biológica do fungo Pleurotus ostreatus. Na matriz primária avaliou-se número de repicagem, velocidade do crescimento micelial, concentração de nutrientes, concentração de dextrose e fontes diversas de nutrientes no meio de cultura em função da eficiência biológica do fungo. Na matriz secundária: tempo de armazenamento, atividade enzimática de lacase (LAC) e manganês peroxidase (MnP) do spawn em função da eficiência biológica de P. ostreatus. Para isto, a pesquisa foi subdividida em dois capítulos. No primeiro avaliou-se a velocidade do crescimento micelial em doze diferentes combinações de meio de cultura utilizando diferentes concentrações de batata, quirera de milho, composto à base de serragem e dextrose, sob efeitos na interferência da eficiência biológica de P. ostreatus. Posteriormente avaliou-se a atividade enzimática LAC e MnP nos spawns e foi correlacionadas à efic... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: Pleurotus ostreatus (shimeji) is among the three most consumed edible mushrooms in Brazil and worldwide. Among the factors related to its high productivity, the most relevant is spawn production. Spawn is the first step in the cultivation of mushrooms and begins with mycelial growth in vitro in culture media, called the primary matrix, later transferred to a solid substrate named as secondary matrix, and then used as an inoculum for the production of mushrooms. The objective of this study was to evaluate the influence of different spawn preparation processes under effect on the biological efficiency of the fungus Pleurotus ostreatus. In the primary matrix, the number of grains, mycelial growth velocity, nutrient concentration, dextrose concentration and various nutrient sources in the culture medium were evaluated according to the biological efficiency of the fungus. In the secondary matrix: storage time, enzymatic activity of laccase (LAC) and manganese peroxidase (MnP) of spawn as a function of the biological efficiency of P. ostreatus. For this, the research was subdivided into two chapters. In the first, the mycelial growth rate was evaluated in twelve different combinations of culture medium using different concentrations of potato, maize cherry, sawdust and dextrose based compounds, on effects on the biological efficiency of P. ostreatus. The LAC and MnP enzymatic activity in the spawns was then evaluated and correlated to the biological efficiency of the first and seco... (Complete abstract click electronic access below)

Resumo: Este trabalho descreve a ação de dois fungos basidiomicetos, Pleurotus sajor caju (020) e Phanerochaete chrysosporium ATCC 24725 na degradação dos corantes naturais urucum hidrossolúvel e carmim (ácido carmínico); como também a combinação destes com o corante urucum oleossolúvel; os corantes sintéticos new coccine, orange G, chrome azurol S; a combinação destes e o efluente da indústria de corantes naturais CHR HANSEN. Além disso, estudou-se o sistema ligninolítico envolvido nesses processos, a redução da demanda química de oxigênio (DQO) do efluente e dos meios de cultivo contendo os corantes, as análises de variações do pH, e do peso seco em relação ao tempo de crescimento. Os fungos foram crescidos em dois diferentes meios agitados: extrato de malte 0,5%, contendo 100 mgIL de corante e no efluente bruto. As análises dos caldos de cultivo foram realizadas no 2°,4°,6°, 8°, 10°e 12°dias de crescimento. A descoloração dos meios de cultivos e do efluente foi verificada através de espectrofotometria de varredura, variando-se o comprimento de onda de 200 a 800 nrn, e a degradação dos corantes por cromatografia líquida de alta eficiência (CLAE). Todos os corantes foram descoloridos em alguma extensão pelos fungos estudados. A eficiência de remoção da cor variou de 50% a 100%. Ambos os fungos mostraram capacidade de descoloração, sendo que Pleurotus sajor caju (020) foi capaz de descolorir, eficazmente o efluente e os corantes naturais e sintéticos, individualmente ou em combinação. Não ocorreu descoloração do efluente por Phanerochaete chrysosporium, mas obteve-se excelente descoloração dos corantes naturais individualmente e dos corantes sintéticos individualmente ou em combinação.
Abstract: This work describes the degradative action of two basidiomycetes, Pleurotus sajor caju (020) and Phanerochaete chrysosporium ATCC 24725, on the following natural or synthetic dyes: a) hydro-soluble annatto (norbixin) b) cannirn (carminic acid); c) a combination of these with the fat-soluble annatto (bixin); d) new coccine; e) orange G; f) chrorne azurol S; g) a combination of these synthetic dyes; h) effluent samples :ITomthe natural dye industry. In addition, the ligninolytic system involved in these processes and the reduction in the chemical oxygen demand (COD) ofthe effluent and ofthe cultivation medium containing dyes were studied. The fungi were grown in two different agitated media: 0.5% malt extract, containing 100 rng/L of different dyes, and in the raw industrial effluent. The cultivation broths were analysed for pH mycelium weight and COD on the 2nd, 4th,6th,8th,10th and 12th days of growth. The decolorization of the culture media and effluent was verified using spectrophotometry, in the wavelength range 200 to 800 nm, and the degradation ofthe dyes was investigated using high performance liquid chromatography (HPLC). All the dyes were decolorised to some extent by the fungi studied with the efficiency of the color removal varying :ITom50 to 100%. Pleurotus sajor caju (020) was capable of efficiently decolorising the effluent and the natural and synthetic dyes, individually or in combination. Effluent decolorization was not observed with Phanerochaete chrysosporium, but this fungus showed an excellent decolorization action on the natural dyes individually and on the synthetic dyes individually or in combination.

Resumo: O objetivo deste trabalho foi avaliar a possibilidade de descoloração/degradação dos corantes índigo e preto enxofre (0,02%, p/v), em suas fórmulas técnicas, por espécies llinhagens de PIeurotus nativas e/ou comestíveis, em meio líquido e sólido, e a degradação do Iodo residual da indústna têxtil acrescido de resíduos lignocelulósicos. Uma seleção, com 14 espécies llinhagens de Pleurotus, foi realizada em meios líquido e sólido; em meio líquido os corantesforam empregadoscomo única fonte de carbono e, em meio sólido foram empregados na presença e ausência de resíduo lignocelulósico.O corante RBBR também foi utilizado no processo de seleção inicial. Uma espécie/linhagem foi testada em meio líquido esterilizado variando-se a concentração de nitrogênio; sob condições naturais, sem esterilização, o teste de biodegradabilidade imediata foi aplicado empregando-se duas espécies/linhagens como inóculo. Em resíduo lignocelulósico misturado ao Iodo (30%, peso úmido), após pasteurização,duas linhagens selecionadas de P. sajor-caju - CCB 020 e PSC 94/03, foram estudadas quanto à capacidade de colonização e degradação do substrato; as avaliações feitas a cada 7 dias foram: fenóis, DQO, umidade, fósforo, potássio, rnagnésio, fibra detergente neutro (FDN) e fibra detergente ácido (FDA), açúcares totais, enzimas ligninolíticas e, após 30 dias, o substrato colonizado foi avaliado quanto ao potencial de mutagenicidade. Os resultados obtidos com o RBBR na seleção das espécies/linhagens ligninolíticas correlacionaram-se com a descoloração observada com os corantes têxteis. Contudo, o processo de descoloração do corante índigo, em meio sólido, só ocorreu na presença do bagaço de cana de açúcar, o que não aconteceu para o corante preto enxofre porque houve descoloração também na ausência do bagaço de cana, dependendo da espécie/linhagem. Seis espécies/linhagens foram pré-selecionadas para testar o Iodo, todas apresentaram descoloração total quando malte e bagaço de cana de açúcar estavam presentes. Em meio líquido, todas as espécies/linhagens apresentaram descoloração, entretanto não foi observada correlação entre peso do micélio e percentual de descoloração. Com relação à razão de descoloração, os resultados indicaram que esta se deu devido à adsorção do corante ao micélio. A espéciellinhagem selecionada para estudo em meio líquido, mudando-se a concentraçãoda fonte de nitrogênio, confirmouque o resultado da descoloração era decorrente de adsorção dos corantes ao micélio. ...

Abstract: The aim of this.study was to evaluate the possibility of índigo and sulphur blackdyes (0,02%,wlv) to be decolorized/degraded by native or /edible or both species/strains of Pleurotus, in liquid and solid media, and the degradation of sludge trom the textile industry together with lignocelullosic wastes. The screening of 14 species/strains of Pleurotus was conducted, in sterile liquid and solid media; in liquid media the dyes were used as the sole source of carbon and, in solid media they were used with and without lignocelullosic wastes. The RBBR dyewas also utilized in thefirst screening. One species/strain was tested in sterilized liquid medium, varying the nitrogen concentration. Under natural conditions, without sterilization, the biodegradability assay was applied using two selected species/strains as inocula. In the lignocelullosic wastes mixed with the sludge (30%, wet weight), afier pasteurization, two strains of P. sajor-caju - CCB 020 and PSC 94/03, were studied to determine their colonization and degradation capability of the substrate; evaluations made every 7 days were: phenols, COD, humidity, phosphorus, potassium, magnesium,fiber detergent neutral (FDN) and fiber detergent acid (FDA), total sugars, ligninolytic enzymes and, afier 30 days, the colonized substrateswere evaluatedfor their mutagenic otential. The results obtained with the RRBR in the screening of the ligninolytic species/strains of Pleurotus correlated with the decolorization observed with the textile dyes. While the decolorization of indigo dye, in a solid media, occurred only in the presence of sugar cane bagasse, this did not happen with black sulphur dye, where the decolorization also occurred in the absence of sugar cane bagasse, depending on species/strain. Six species/strains were selected to test the sludge and ali of them showed total decolorization when malt and sugar cane bagasse were present. In liquid media, all species/strains showed some decolorization, but no correlation was observed between weight and percentage decolorization. Regarding the decolorization rate, the results showed that the decolorization was due to dye adsorption by fungal mycelia. The selected species/strain selected for study in liquid media, under different nitrogen concentration, confirrned that decolorization is related to dye adsorption to fungal mycelia. For both dyes, production of ligninolytic enzymes was either not detected or extremely low. There was no difference in decolorization due to nitrogen concentrations in the medium. In the Ibama's ready biodegradability assay, the dyes were also classified as not easily biodegradable. ...

Full textAbstract:
Nel corso del tirocinio di tesi si sono studiate nuove metodologie per la produzione di enzimi idrolitici per matrici lignocellulosiche vegetali di scarto.
In primis è stato valutato un nuovo metodo di produzione enzimatica utilizzando il fungo basidiomicete Pleurotus ostreatus all’interno di un fermentatore in stato solido (SSF) movimentando periodicamente il substrato mediante un'estrusione meccanica e confrontando i risultati con esperimenti analoghi ma privi di estrusione.
In seguito si è valutata l’attività enzimatica prodotta dal fungo Agaricus bisporus (il comune Champignons) cresciuto tramite una fermentazione in stato solido priva di qualsiasi movimentazione.
Infine gli estratti enzimatici ricavati dalle prove precedenti sono stati utilizzati allo scopo di idrolizzare matrici vegetali di scarto provenienti dall’industria cerealicola e viti-vinicola.
I risultati del lavoro risultano promettenti e si osserva come sia gli estratti ricavati da fermentazioni su stato solido dinamiche (con Pleurotus) che quelle su stato solido statiche (con Agaricus) sono in grado di favorire l’idrolisi e la degradazione delle matrici vegetali favorendo la fuoriuscita di componenti di interesse come zuccheri riducenti e polifenoli.

Full textAbstract:
This study was conducted to determine the drying characteristics of oyster mushroom (Pleurotus ostreatus) at 50, 60 and 70 °C. Pleurotus ostreatus were cleaned and dried in a laboratory cabinet dryer. The drying data were fitted to six model equations namely Newton, Pabis and Henderson, Logarithmic, Two-term diffusion, Wang and Singh, as well as Modified Henderson and Pabis equations. The goodness of fit of the models were evaluated by means of the coefficient of determination (R2), root mean square error (RMSE) and reduced chi-square (χ2). The Logarithmic model best describes the drying data and could be used to predict its drying behaviour. Keywords: oyster mushroom; thin-layer drying; characteristics; modelling

Forest and agricultural waste can be a major development and ecological opportunity. Therefore, it is reasonable to use biological waste further to produce energy and for the manufacture of certain products with high added value, such as, for example, the cultivation of fungi and, consequently, the production of biocatalysts with high market value. In addition, the use of agriculture waste for Oyster mushroom (Pleurotus ostreatus) growth can be integrated to waste management and the development of the bioeconomy. The cultivation of P. ostreatus using waste plant biomass from agriculture (straw, grass, courgettes, cucumbers, peaches, apricots, pears, and peppers) was performed in order to obtain the highest increase in biomass production of the cultivated mushroom and as a potential source of α-amylase, with high catalytic activity. The highest α-amylase activities were achieved when pears or apricots were used as a substrate for P. ostreatus cultivation.

Full textAbstract:
During the granting period, we performed the following projects: Firstly, we differentially measured glucan content in several pleurotus mushroom strains. Mushroom polysaccharides are edible polymers that have numerous reported biological functions; the most common effects are attributed to β-glucans. In recent years, it became apparent that the less abundant α-glucans also possess potent effects in various health conditions. In our first study, we explored several Pleurotus species for their total, β and α-glucan content. Pleurotuseryngii was found to have the highest total glucan concentrations and the highest α-glucans proportion. We also found that the stalks (stipe) of the fruit body contained higher glucan content then the caps (pileus). Since mushrooms respond markedly to changes in environmental and growth conditions, we developed cultivation methods aiming to increase the levels of α and β-glucans. Using olive mill solid waste (OMSW) from three-phase olive mills in the cultivation substrate. We were able to enrich the levels mainly of α-glucans. Maximal total glucan concentrations were enhanced up to twice when the growth substrate contained 80% of OMSW compared to no OMSW. Taking together this study demonstrate that Pleurotuseryngii can serve as a potential rich source of glucans for nutritional and medicinal applications and that glucan content in mushroom fruiting bodies can be further enriched by applying OMSW into the cultivation substrate. We then compared the immune-modulating activity of glucans extracted from P. ostreatus and P. eryngii on phagocytosis of peripheral blood neutrophils, and superoxide release from HL-60 cells. The results suggest that the anti-inflammatory properties of these glucans are partially mediated through modulation of neutrophileffector functions (P. eryngiiwas more effective). Additionally, both glucans dose-dependently competed for the anti-Dectin-1 and anti-CR3 antibody binding. We then tested the putative anti-inflammatory effects of the extracted glucans in inflammatory bowel disease (IBD) using the dextran sulfate sodium (DSS)–induced model in mice. The clinical symptoms of IBD were efficiently relieved by the treatment with two different doses of the glucan from both fungi. Glucan fractions, from either P. ostreatus or P. eryngii, markedly prevented TNF-α mediated inflammation in the DSS–induced inflamed intestine. These results suggest that there are variations in glucan preparations from different fungi in their anti-inflammatory ability. In our next study, we tested the effect of glucans on lipopolysaccharide (LPS)-induced production of TNF-α. We demonstrated that glucan extracts are more effective than mill mushroom preparations. Additionally, the effectiveness of stalk-derived glucans were slightly more pronounced than of caps. Cap and stalk glucans from mill or isolated glucan competed dose-dependently with anti-Dectin-and anti-CR-3 antibodies, indicating that they contain β-glucans recognized by these receptors. Using the dextran sulfate sodium (DSS)-inflammatory bowel disease mice model, intestinal inflammatory response to the mill preparations was measured and compared to extracted glucan fractions from caps and stalks. We found that mill and glucan extracts were very effective in downregulatingIFN-γ and MIP-2 levels and that stalk-derived preparations were more effective than from caps. The tested glucans were equally effective in regulating the number of CD14/CD16 monocytes and upregulating the levels of fecal-released IgA to almost normal levels. In conclusion, the most effective glucans in ameliorating some IBD-inflammatory associated symptoms induced by DSS treatment in mice were glucan extracts prepared from the stalk of P. eryngii. These spatial distinctions may be helpful in selecting more effective specific anti-inflammatory mushrooms-derived glucans. We additionally tested the effect of glucans on lipopolysaccharide-induced production of TNF-α, which demonstrated stalk-derived glucans were more effective than of caps-derived glucans. Isolated glucans competed with anti-Dectin-1 and anti-CR3 antibodies, indicating that they contain β-glucans recognized by these receptors. In conclusion, the most effective glucans in ameliorating IBD-associated symptoms induced by DSS treatment in mice were glucan extracts prepared from the stalk of P. eryngii grown at higher concentrations of OMSW. We conclude that these stress-induced growing conditions may be helpful in selecting more effective glucans derived from edible mushrooms. Based on the findings that we could enhance glucan content in Pleurotuseryngii following cultivation of the mushrooms on a substrate containing different concentrations of olive mill solid waste (OMSW) and that these changes are directly related to the content of OMSW in the growing substrate we tested the extracted glucans in several models. Using dextran sulfate sodium (DSS)–inflammatory bowel disease (IBD) mice model, we measured the colonic inflammatory response to the different glucan preparations. We found that the histology damaging score (HDS) resulting from DSS treatment reach a value of 11.8 ± 2.3 were efficiently downregulated by treatment with the fungal extracted glucans, glucans extracted from stalks cultivated at 20% OMSWdownregulated to a HDS value of 6.4 ± 0.5 and at 80% OMSW showed the strongest effects (5.5 ± 0.6). Similar downregulatory effects were obtained for expression of various intestinal cytokines. All tested glucans were equally effective in regulating the number of CD14/CD16 monocytes from 18.2 ± 2.7 % for DSS to 6.4 ± 2.0 for DSS +glucans extracted from stalks cultivated at 50% OMSW. We finally tested glucans extracted from Pleurotuseryngii grown on a substrate containing increasing concentrations of olive mill solid waste (OMSW) contain greater glucan concentrations as a function of OMSW content. Treatment of rat Intestinal epithelial cells (IEC-6) transiently transfected with Nf-κB fused to luciferase demonstrated that glucans extracted from P. eryngii stalks grown on 80% OMSWdownregulatedTNF-α activation. Glucans from mushrooms grown on 80% OMSW exerted the most significant reducing activity of nitric oxide production in lipopolysaccharide (LPS) treated J774A.1 murine macrophages. The isolated glucans were tested in vivo using the Dextran Sodium Sulfate (DSS) induced colitis in C57Bl/6 mice and found to reduce the histology damaging score resulting from DSS treatment. Expression of various intestinal cytokines were efficiently downregulated by treatment with the fungal extracted glucans. We conclude that the stress-induced growing conditions exerted by OMSW induces production of more effective anti-inflammatory glucans in P. eryngii stalks.
