Abstract

Abstract: The saccharification processes of rice straw were investigated using three different microwave irradiation treatment methods.The results showed that rice straw pretreated by combining microwave irradiation with alkali treatment together was the most favorable approach for saccharification of rice straw under this test condition.The effects of microwave irradiation power and irradiation time on saccharification was examined and the saccharification conditions were optimized by an orthogonal test.The optimal saccharification conditions were:substrate concentration 10 g/L,temperature 45℃,pH value 4.8 and enzyme loading 20 mg/g substrate.

Key words: microwave irradiation, rice straw, saccharification
