Beschreibungen/Notizen

• ► Pleurotus ostreatus mushrooms were enriched with selenium. ► Consumption of 10g of mushrooms can provide the recommended Se daily intake. ► Low-price agricultural residue can be used to produce selenium-enriched mushrooms. Pleurotus ostreatus fungus forms an edible mushroom that possesses important nutritional and medicinal properties. Selenium (Se) is essential to human diets and it is in low concentration in the soil, and consequently in food. P. ostreatus was grown in coffee husks enriched with various concentrations of sodium selenite. The biological efficiency of P. ostreatus was affected by the addition of high concentrations of Se. The highest level of Se absorption was obtained by adding 51mgkg1 of sodium selenite. The mushrooms from first flush contained more Se than the further flushes. These results demonstrate the great potential of coffee husks in the production of Se-enriched mushrooms and show the ability of this fungus to absorb and biomagnify Se.
