Development of chemical property and process models for a new fermentation approach

Bioethanol is well-established as an alternative to petroleum-based fuels. A current roadblock in ethanol fermentation is end-product inhibition: where the increasing concentration of ethanol slows the growth of the yeast cells and their ability to ferment biomass. There is work being done to use existing separation technologies to remove ethanol throughout the reaction to avoid end-product inhibition, however these methods are often energy-intensive and therefore not feasible on a commercial scale.
