  • Patent number: 9725742
    Abstract: A process for obtaining high ethanol yield from the fermentation of an energy crop and for producing a nutritionally enhanced feed co-product is provided. In particular, the process includes converting non-fermentable polysaccharides in an energy crop into fermentable sugar. The fermentable sugars may be fermented into ethanol thereby enhancing the ethanol yield. In addition, separation of ethanol from the fermentation product yields a whole stillage product having enhanced protein content and reduced fiber content. The process requires little or no modification to the configuration of existing commercial ethanol facilities.

  • Patent number: 9574212
    Abstract: The disclosure provides a process for producing a fermentation product from a lignocellulosic feedstock. The process describes soaking a lignocellulosic feedstock in an aqueous solution to produce a soaked feedstock. The soaked feedstock is at least partially dewatered and the at least partially dewatered feedstock is subjected to pretreating in the presence of sulfur dioxide, sulfurous acid or a combination thereof to produce a pretreated feedstock composition. The pretreated feedstock composition is fed to an enzymatic hydrolysis in which the concentration of dissolved solids fed to the enzymatic hydrolysis is at least 50% (w/w) of the concentration of dissolved solids in the pretreated feedstock composition. The cellulose in the pretreated feedstock composition is hydrolyzed with cellulase enzymes in the presence of the dissolved solids to produce glucose. The glucose is fermented to produce the fermentation product.
