This study aimed to investigate the effects of pulsed electric field (PEF), ultrasound (US), and combined pretreatments (PEF-US) on mass transfer, rehydration capacity, microstructure, nutritional quality shiitake mushrooms (Lentinus edodes). The results indicated that could accelerate transfer during hot-air drying process at 65 °C, resulting in lower time energy requirement than control. Mean...

The centesimal composition and the physical and chemical analyses of Lentinus strigosus, an edible mushroom occurring in the Brazilian Amazon and produced in alternative substrates based on wood and agroindustrial residues, were evaluated. For this purpose, the C, N, pH, soluble solids, water activity, protein, lipids, total fiber, ash, carbohydrate, and energy levels were determined. The subst...

To obtain extracts rich in the organic forms of selenium with putative cancer-preventive properties more effective than those of selenizedyeast, Lentinula edodes mycelia were cultivated in media enriched with selenium at concentrations from 0 to 20 μg mL, by addition of sodium selenite either before inoculation or after three days of mycelial growth. The total selenium content of submerged cult...

The uracil auxotrophic monokaryotic strain 423-9 of Lentinula edodes was crossed with nine monokaryons (cro2-2-9, W66-1, xd2-3-2, QingKe 20A, 241-1-1, 9015-1, L66-2, 241-1-2, and Qing 23A) derived from wild type strains of L. edodes. Nine dikaryotic hybrids were established from these crosses. These hybrids were fruited and 496 single spore isolates were obtained. Among these single spore isola...

Shiitake (Lentinula edodes (Berk.) Pegler) mushrooms have a reputation as a healthy food, in part from the abundance of different polysaccharides that may have functional food activities. However, the total polysaccharide content of mushrooms may not represent the functional food activity if they contain significant concentrations of starch. There are few reports characterizing the starch conte...

Four Lentinula edodes strains (Le10, 46, K2, Assai) were assessed for their antagonistic effect on four filamentous fungus species of agricultural importance (Helminthosporium euphorbiae, Helminthosporium sp, Fusarium solani and Phomopsis sojae) and on Alagoas serotype of Vesicular Stomatitis Virus (VSA). The L. edodes strains studied had variable effects on the filamentous fungi and on VSA. Th...

Three common species of cultivated edible mushrooms were analyzed in terms of their antioxidant capacity and total phenolics content. Fruiting bodies of Agaricus bisporus, Pleurotus ostreatus and Lentinula edodes were subjected to blanching in a citric acid solution for five minutes and boiling in water for fifteen minutes. Both ethanolic and water extracts were obtained from the mushrooms and ...

From fruiting bodies of L. edodes strain L-54, single-spore isolates (SSIs) were collected. Two parental types of L-54 were regenerated via monokaryotization. By means of random-amplified polymorphic DNA (RAPD), DNA samples from L-54, its two parental types, and 32 SSIs were amplified with arbitrary primers. Dedikaryotization was demonstrated, and 91 RAPD-based molecular markers were generated....
