Nutritional value and biomass yield of the edible mushroom Pleurotus ostreatus cultivated on different wastes in Egypt

Abstract

Mushroom yield (number of fruit bodies, fresh biomass gain and pileus diameter) and biochemical composition (proteins, fats, carbohydrates, ash, fiber, moisture, metals and amino acids). Pleurotus ostreatus was evaluated using different natural wastes for cultivation either singly or in combination. The most suitable substrate for fresh, high number, large sized pileus yield with high nutritional facts was the combined mixture of wheat and rice straws (1:1). This mushroom was rich in proteins, fibers, carbohydrates, metals with low fat content. P. ostreatus cultivated in the combined mixture was found to be rich in amino acids with glutamic and aspartic acids being of the highest quantities. Paddy and bamboo leaves not suited the quality and quantity of mushroom gain.
