Patent Summary

A process for converting mixed sugars like glucose, galactose, and arabinose into ethanol using a modified yeast cell. The process involves introducing genes into the yeast cell to allow it to ferment all three sugars. The genes include xylose isomerase for converting xylose to xylonate, xylose reductase and xylitol dehydrogenase for converting xylose to ethanol, and deletion of the aldose reductase gene to reduce competing pathways. This allows efficient fermentation of mixed sugar feedstocks containing glucose, galactose, and arabinose.
