Agricultural Wastes as Potential Substrates for White Oyster Mushroom (Pleurotus ostreatus)

Abstract

This study aimed to evaluate the White oyster mushroom (P. ostreatus) grown in different agricultural wastes substrates namely; Rice straw (treatment 1), Water hyacinth (treatment 2), and Oil palm empty fruit bunches (treatment 3). Based on the result, it confirmed that White oyster mushroom (P. ostreatus) could be grown efficiently in the Rice straw which was very abundant agricultural waste in Rice producing countries. The results will support the study of (Ahlawat, 2005) stated that mushroom prefers high cellulose, low lignin containing the substrate and induces a variety of cellulolytic enzymes since Rice Straw founded to be high cellulose and low in lignin. Rice byproduct also found to have high in nitrogen content which a very essential element for mycelia growth, thus, mycelia growth is an essential in primordial development.
