ABSTRACT:
A process for the production of ethanol from a carbohydrate substrate such as glucose comprising culturing a flocculant strain of Zymomonas mobilis such as ATCC 31822, in a semi-batch manner periodically allowing the flocculent cells to settle, removing the ethanol containing supernatant and introducing fresh fermentation medium into the fermentor.
