Abstract
A method for the fermentation of pre-treated and liquefied starch to ethanol where the starch material is saccharified to glucose by the enzyme amyloglucosidase, and the glucose is fermented to ethanol by the micro-organism Zymomonas mobilis in a single fermentation vessel. The ratio of amyloglucosidase cells to Zymomonas mobilis cells can be varied so that saccharification and fermentation steps occur at the same rate. The starch concentration is in the range 10 % to 30 % (w/v).
