title: The effect of microwave irradiation on enzymatic hydrolysis of rice straw.
abstract: A series of experiments involving microwave irradiation were carried out to evaluate the effect of microwave irradiation on enzymatic hydrolysis of rice straw. Compared with microwave irradiation free hydrolysis, rice straw pretreated by combining microwave irradiation with alkali could increase the initial hydrolysis rate but the hydrolysis yield remained unchanged. When the enzyme solution was treated by microwave irradiation, the initial hydrolysis rate increased slightly, but the yield was decreased remarkably. Its optimal hydrolysis conditions were temperature (45 degrees C), pH (4.8) and enzyme loading (20 mg g(-1) substrate), which was determined by an orthogonal experiment. When intermittent microwave irradiation was used, initial hydrolysis rate was greatly accelerated but the yield was decreased slightly. Its optimal hydrolysis conditions were temperature (50 degrees C), pH (4.8) and enzyme loading (20 mg g(-1) substrate), which was determined by another orthogonal experiment.
