Effect of Different Substrates on Yield and Nutritional Value of Pleurotus ostreatus and Evaluation of its Phyto-chemical and Antibacterial Properties

Mushrooms are fleshy, spore bearing fruiting bodies or fungus. They belong to the class Basidiomycetes, order; Agaricales. According to Chang and Miles mushroom is “a macro-fungus with a distinctive fruiting body which can be either epigeous or hypogeous. The study was conducted to observe the effect of different substrates on growth, yield and nutritional composition of oyster mushroom (Pleurotus ostreatus). Four different substrate Wheat straw, paddy straw, rice bran, sugarcane baggase supplemented with gram husk and wheat bran were observed in different ratio. The results indicated that different substrates showed significant different in growth, yield and nutritional composition of Pleurotus ostreatus. Wheat straw supplemented with gram husk and wheat bran gave maximum yield as compared with other substrates, but with increase in supplemented substrates showed adverse effect on growth and yield of Pleurotus ostreatus.
