Technical Abstract: Technology for engineering an industrial yeast strain for production of ethanol from glucose, mannose, arabinose, and xylose (GMAX-yeast) using both corn starch and cellulosic feedstocks with simultaneous production of valuable coproducts, including biodiesel, will be discussed. A stable industrial GMAX-yeast strain is being developed by incorporating the genes for anaerobic xylose and arabinose utilization identified in high-throughput automated screening in a plasmid-based yeast and evaluating the resulting strain for ethanol production. Stably incorporating these plasmids into an industrial yeast strain of Saccharomyces cervisiae that is already tolerant to environments in the production biorefinery will produce a strain that is capable of ethanol production from any fermentable feedstock. Initially a cellulosic strain will be produced for use on acid or base hydrolysates of cellulosic biomass for high levels of cellulosic ethanol production.
