Endogenous lipase for metal reduction in distillers corn oil

Abstract

Provided herein are compositions, methods, systems associated with propagation and fermentation, and co-products of biochemical production processes, for example, a DCO co-product resulting from converting oil containing grains into bio chemicals via fermentation in the presence of endogenous esterase. The DCO resulting from the processes exhibits lower metal ion content relative to a DCO obtained in the absence of endogenous fermentation with an esterase such as a lipase. The DCO is useful as a feedstock for the production of renewable diesel.
