Abstract
Oyster mushroom (Pleurotus spp.) is a delicious edible fungus with high nutritional and medicinal values. Itcontains all essential amino acids and several polysaccharides.Five strains of oyster mushroom werecultivated on rice straw sterilized at 121oC for 100 min and on rice straw piled for6-7 days at 60-70oC. The results showed that of5 oyster mushroom strains, PN1 showed the highest growth rate. In addition, sterilized straw was the most suitable material for the growth of PN1 with bio-efficiency at 73.8%. For further investigation, PN1 was cultured on a mixture of different materials including straw and some agricultural wastes such as cotton seed hull, sawdust, husk, and rice bran. It showed that the mix(in percent) with straw (84), cotton seed hull (10), rice bran (5) and CaCO3(1)was the best medium for the mycelial growth and fruitingbody yield and the bio-efficiency of PN1reached 77.4%.
