• Simultaneous saccharification and ethanol fermentation (SSF) of sago starch using amyloglucosidase (AMG) and immobilized Zymomonas mobilis ZM4 on sodium alginate was studied. The immobilized Zymomonas cells were more thermo-stable than free Zymomonas cells in this system. The optimum temperature in the SSF system was 40℃, and 0.5% (v/w) AMG concentration was adopted for the economical operation of the system. The final ethanol concentration obtained was 68.3 g/l and the ethanol yield, Y_<p/s>, was 0.49 g/g(96% of the theoretical yield). After 6 cycles of reuse at 40℃ with 15% sago starch hydrolysate, the immobilized Z. mobilis retained about 50% of its ethanol fermenting ability.
