Raw starch can be effectively saccharified in an enzyme reaction system containing sttrition-milling media. In order to develop an effcient attrition-coupled bioreactor(bioattritor), a rotating drum type bioattitor was construced, and its optimal operation conditions and power consumptions were evaluated. The optimal conditions for 3l bioattritor were 4 baffled, baffle size of 1:0.05 (the ratio of drum diameter to baffle), drum rotation speed of 100 rpm, and 1.33g of 3 mm glass bead/g of raw corn starch.
