Abstract
The present invention provides improved fermentation processes, including for use in an ethanol production process. The improved fermentation processes include applying at least one fatty acid oxidizing enzyme (especially a lipoxygenase) in a fermentation process. The improved fermentation process may also involve the addition of various additional enzymes and growth stimulators for the fermenting microorganisms, including vitamins and mineral.
Claims14
A process for producing ethanol in a fermentation medium which process comprises a fermentation step with a microorganism, comprising subjecting the fermentation medium to at least one fatty acid oxidizing enzyme.
A process for producing ethanol, comprising
- (a) milling whole grains;
- (b) liquefying the product of step (a);
- (c) saccharifying the liquefied material;
- and
- (d) fermenting the saccharified material using a microorganism, wherein the fermentation process further comprises contacting the fermentation media with at least one fatty acid oxidizing enzyme.
