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 includes systems and methods for hydrolyzing (e.g., pretreatment and/or enzymatic hydrolysis) lignocellulosic biomass into one or more sugars such as pentose and glucose sugars. The present disclosure includes configurations that incorporate flashing and/or liquid cooling so as to permit desirable throughput. The present disclosure also includes a liquefaction configuration so as to permit desirable (e.g., continuous high volume) throughput.

Abstract: Methods, compositions, and systems for propagation and fermentation, particularly large scale operations for production of ethanol and dried distiller's grain are provided. Addition of urease and urea to propagation and/or fermentation improves yeast health, fermentation efficiency, and quality and quantity of DDG. Urease can be in reagent form or can be endogenous to the natural feedstock.

Abstract: Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.
Abstract: Described are food products including doughs, extrudates, and finished food products derived therefrom, that contain zein protein, e.g., zein protein ingredient, wherein the zein protein improves processing or textural characteristics of the food product.

Abstract: Provided are methods and systems for remediating toxins present in feedstock that are used in processes to produce ethanol and other products.
Abstract: Methods and system for producing a slip stream of sugar, for example for use in the production of one or more chemicals, in ethanol fermentation facilities. In some embodiments, the methods and systems have little to no impact on the level of production of ethanol, despite also producing a slip stream of sugar. The methods and systems can be implemented in dry mill ethanol, wet mill ethanol, and lignocellulosic ethanol fermentation facilities and processes.
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 to a dewatering systems, and related methods, that are adapted to convey lignocellulosic biomass to separate at least a portion of the water from a lignocellulosic biomass slurry and accumulate the dewatered lignocellulosic biomass. The dewatering system also includes a headspace occupied by a gas that is at a pressure that facilitates transferring the accumulated biomas into a pretreatment reactor having a pressurized headspace. Such a dewatering system can prevent undue mixing and backflow of gas (e.g., steam) from the pretreatment reactor.
Abstract: The present disclosure relates to using a source of one or more monosaccharides derived from a pulp or paper mill waste by-product for propagating microorganisms (e.g., yeast or bacteria). If desired, after propagation, the microorganisms can then be used to ferment one or more monosaccharides derived from a pulp or paper mill waste by-product into one or more biochemicals. Optionally, a stillage composition can be included in propagation medium to facilitate propagation and/or a stillage composition can be used to facilitate enzymatic hydrolysis of oligosaccharides and/or polysaccharides in a pulp or paper mill waste by-product to form monosaccharides.
