Abstract
The effect of chemically disinfected wheat straw on the proximate composition and mineral content of oyster mushrooms (Pleurotus ostreatus) was investigated. Different treatment levels were used in combination with different times (12, 18 and 24 hours) and doses of Formalin (250, 500 or 750 ppm) and Bavistin (75 ppm), and regulation was compared. The highest production in terms of protein in percent (25.71) was obtained in wheat straw processed with Formalin (500 ppm) + Bavistin (75 ppm) for 18 hours. Pleurotus ostreatus grown on wheat straw treated with Formalin (750 ppm) + Bavistin (75 ppm) for 18 hours yielded the highest percentage of crude fiber (21.40), Ca (22.15 mg/100 gm) and Zn (15.10mg/100 gm) content. So, sterilizing wheat straw with Formalin (750 ppm) + Bavistin (75 ppm) for 18 hours may be an economically effective treatment for the nearest compression and the higher mineral oyster mushroom content.
