Immunomodulating activities of cultivated maitake medicinal mushroom Grifola frondosa (Dicks.: Fr.) S.F. Gray (higher Basidiomycetes) on peripheral blood mononuclear cells.

Grifola frondosa is a culinary-medicinal mushroom that contains several physiologically active compounds, of which polysaccharides, specifically β-glucans, are known to possess immunomodulating properties. Its extracts are studied for application as adjuncts for chemotherapy, and experiments in animal models support the use of this mushroom for cancer treatment. The effect of extracts obtained from mushrooms cultivated on different substrates and their capacity of inducing the secretion of cytokines from human peripheral blood mononuclear cells were studied.

Cultivation and bioactivity assessment of Grifola frondosa fruiting bodies on olive oil press cakes substrates.

Grifola frondosa, a medicinal and edible mushroom, was cultivated on substrates composed of olive oil press cakes with different supplements. Crude extracts were prepared from mature fruiting bodies and tested for their capacity to stimulate splenocyte proliferation. Two wild-growing fruiting bodies were extracted for comparison.

The use of spent brewery grains for Pleurotus ostreatus cultivation and enzyme production.

In the brewing industry, spent brewery grains (SBGs) are byproducts with a low economic value. The potential use of this leftover as a substrate ingredient for Pleurotus ostreatus fruiting body cultivation and enzyme production was evaluated. The best substrate mixture for P.

Solid-state cultivation of Grifola frondosa (Dicks: Fr) S.F. Gray biomass and immunostimulatory effects of fungal intra- and extracellular beta-polysaccharides.

Grifola frondosa strain GF3, was cultivated on solid-state substrate consisting of milled whole corn plant (Zea mays) and olive press cake supplemented with mineral additives and olive oil. Maintenance of the moisture content in the solid substrate is of crucial importance. Moistures higher than 70% promote growth of G.
