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.

Abstract: Methods, compositions, and systems for steeping, propagation and fermentation, particularly large-scale operations for production of starch and ethanol and fermentation product streams are provided. Addition of mycotoxin mitigating enzymes or microorganisms expressing mycotoxin mitigating enzymes to steeping, propagation, and/or fermentation tanks, and/or to post-fermentation product streams, mitigates mycotoxin levels in fermentation co-products obtained from mycotoxin contaminated feedstocks.

Abstract: The present disclosure relates to methods and systems for refining grain oil compositions using an esterase enzyme component, water, bleaching processes, and combinations thereof, and related compositions produced therefrom having one or more reduced color values. The present disclosure also relates to methods of using said compositions, e.g., as mineral oil replacements.

Abstract: The present disclosure describes methods for reducing the content of minerals, metals, ions, and/or other undesirable contaminants in vegetable oil, such as corn oil, obtained from fermentation of ground vegetable material. In one aspect, the methods herein produce distiller's corn oil having low amounts of minerals, metals, ions, and/or other contaminants rendering the corn oil more suitable for various further uses, such as biofuel production, with little to no additional refining.

Abstract: Methods to prepare vegetable oil compositions having an elevated ethyl ester content are provided.

Abstract: The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.

Abstract: The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition and/or feedstock to make diesel.

Abstract: The subject disclosure relates to a method for producing a fermentation product from biomass that has been pre-treated in a pre-treatment system and separated into a liquid component and a first solids component. The method comprises: (a) treating the liquid component in a filtration system comprising at least one nano-filter to produce a treated liquid component, and to remove an acid from the liquid component; (b) supplying the treated liquid component, a fermenting organism, and agents to a fermentation system; (c) recovering the fermentation product from the fermentation system; and (d) supplying the acid for re-use in the pre-treatment system. In many embodiments, the biomass comprises lignocellulosic material and the liquid component comprises pentose (e.g., xylose).
