The Acetone Butanol Ethanol $($ABE$)$ fermentation was a popular process to produce

acetone for use in explosive manufacturing during the second world war. In the last few

decades, the interest has shifted to the production of butanol from this process. The

fermentation process involves fermentation of starch derived glucose into butanol.

However, butanol is a toxic to most strains of Clostridium acetobutylicum cells at

concentrations above $20\frac{g}{L}.$ Develop a processing scheme to maximize the productivity

$(g$ butanol produced $\frac{?}{hr}-g$ dry cells$)$ and yield $(g$ butanol $\frac{?}{g}$ glucose$)$ of the butanol from

the ABE Process. $(6$ points$)$
