Technical Abstract: Current ethanol dry grind and wet mill processes for fuel ethanol production from starch, yield substantial amounts of corn oil as one of the byproducts. This crude corn oil is a suitable feedstock for the production of fatty acid ethyl esters for use as biodiesel, which could be produced on-site. The conversion of crude corn oil to fatty acid ethyl esters requires purification and transesterification and purification of the corn oil triacylglycerides to yield the constituent ethyl ester and glycerol components. Mitsubishi Chemical Corporation has developed ion exchange resin beads that have the capability of anchoring a lipase catalyst on the surface. Since no denaturing agent or heat is used, the enzyme retains its function upon immobilization. These lipases can be expressed inexpensively in the dry grind refinery yeast and be used for secondary ethyl ester production with ethanol and from corn oil at the crossover biorefinery.
