A continuous process involving simultaneous saccharification and fermentation of liquefied starch has been developed using Zymomonas mobilis. Amyloglucosidase retention and cell recycle have been effected by using an Amicon hollow-fiber membrane system with a MW cutoff of 5000. Relatively high productivities of up to 60 g l-1 h-1 have been achieved at ethanol concentrations of 60-65 g/l. The system also offers the potential for reduced enzyme requirements for saccharification. (Refs. 21).
