摘要：
The utilization of wastes by bioconversion into value added products may be an innovative solution to the environmental waste problem. The objectives of this work were to study the production of enzymes (amylase, invertase, filter paper cellulase, carboxy methyl cellulase, xylanase and chitosanase) and bioactive phenolic and antioxidant compounds by Pleurotus ostreatus NRRL-0366 in solid state fermentation (SSF) using different agricultural residues (rice straw and pineapple waste) at different concentrations. Highest amylase activity (93.75U/gds) was obtained with concentration (triple amount of pineapple waste mixed with rice straw). The maximum activity of invertase enzyme (69.6 U/gds.) was achieved with double amount of rice straw mixed with pineapple waste. Maximum filter paper cellulase. Activity (18.9U/gds.) was observed when P. ostreatus was grown on rice straw only. The maximum activities of carboxy methyl cellulase, xylanase and chitosanase enzymes (56.55, 55.35 and 46.5 U/gds), respectively were achieved with concentration (triple amount of rice straw mixed with pineapple waste) respectively. The total polyphenol and antioxidant activities of seven extracts were determined.
