摘要：Simultaneous saccharification and fermentation of dextrinized cassava starch to glucose and alcohol, respectively, were carried out by co-immobilized Zymomonas mobilis and immobilized glucoamylase (IG). Calcium alginate-entrapped cells and IG (4: 1 ratio) gave an alcohol productivity of 0.30 g/gww cells /h in a batch fermentation process. For continuous fermentation, 54.3 g/l alcohol was produced at a dilution rate of 0.3/h. 60% of the initial activity was lost within 3 days and, thereafter; the system entered a slowly decreasing phase of alcohol production.
