Abstract

The present invention relates to a process to enhance ethanol yield from molasses fermentation, by addition of enzymes (depolymerising enzymes and xylose isomerase) which convert unfermentable sugars into fermentable sugars. The anaerobic fermentation of the increased amount of fermented sugars facilitated by Saccharomyces cerevisae results in higher level of ethanol yield.
