Mushrooms have been used for food and medicinal purposes since ancient period. The β-glucans found in
mushrooms are currently considered to be responsible for some of the medicinal properties of mushrooms,
thereby motivating studies on characterization of these compounds. In our study, we tested the effect of nitrogen
supplementation on the productivity and nutritional composition of Pleurotus ostreatusmushrooms. The fungi
were grown in various substrates supplemented with urea or rice bran, and the biological efficiency, mineral
composition, protein and β-glucan content were evaluated. The growth of P. ostreatusin substrates with nitrogen
supplementation increases the mushroom’s productivity and nutritional value. Our results also indicate that
nitrogen supplementation, a simple technique, efficiently increases the β-glucan content of mushrooms.
