Abstract 

To produce ethanol more economically than in a conventional process, it is necessary to attain high productivity and low production cost. To this end, a continuous ethanol production from sago starch using immobilized amylogucosidase (AMG) and Zymomonas mobilis cells was studied. Chitin was used for immobilization of AMG and Z. mobilis cells were immobilized in the form of sodium alginate beads. Ethanol was produced continuously in an simultaneous saccharification and ethanol fermentation (SSF) mode in a pacekd bed reactor. The maximum ethanol productivity based on the void volume, Vv, was 37 g/l/h with ethanol yield, Yp/s, 0.43 g/g (84% of the theoretical ethanol yield) in this system. The steady-state concentration of ethanol (46 g/l could be maintained in a stable manner over two weeks at the dilution rate of 0.46 h-.
