Abstract:
Methods for production of ethanol, distiller's corn oil, and enhanced co-products are disclosed. Methods include obtaining a mixture of one or more co-products of an alcohol production process, which may include wet cake, performing hydrolysis of polysaccharides in the mixture to generate fermentable sugars, fermenting the fermentable sugars in the mixture to produce alcohol, distilling the mixture to remove alcohol from the mixture thereby producing alcohol-containing distillate and enhanced whole stillage, removing released oil from the fermented mixture before distillation and/or from the enhanced whole stillage after distillation, and recovering enhanced wet distiller's grains, enhanced thin stillage, and/or enhanced dried distiller's grains. Compositions disclosed herein include enhanced dried distiller's grains having a crude protein content of at least 45% on a dry weight basis and having a total fat content of less than 10% on a dry weight basis.
Abstract:
Methods for production of alcohol, biomolecules, and/or microbial biomass using cellulosic pulp as a feedstock are provided. Cellulosic pulp is contacted with an enzyme composition to produce fermentable sugars, which are used as a carbon source for a microorganism to produce alcohols or biochemicals by fermentation and/or to produce only microbial biomass.

Abstract:
Methods, systems, and compositions for propagating a fermentation microorganism that can have improved product yield during fermentation of a hydrolysate containing at least one growth inhibitor, including ethanol. In some embodiments, the method comprises: (a) providing a hydrolysate for fermentation, wherein the hydrolysate comprises exogenous ethanol in an amount of at least 10 g/L; (b) providing a propagation reactor containing: a propagation medium comprising: the hydrolysate in an amount of at least 25% by volume and glucose in an amount of greater than 14 g/L; and a first cell mass of a fermentation microorganism; and (c) propagating the first cell mass in the propagation medium for a time period to form a second cell mass of the fermentation microorganism that is greater than the first cell mass.
Abstract:
A method for making comestible protein meal includes: producing an alcohol based fuel (such as ethanol) from a starch-based plant feedstock (such as duckweed); then separating stillage that remains afterwards into solids and a thin stillage; drying the solids to a comestible protein meal (minimum 40% protein); and recycling the thin stillage as plant fertilizer. Another method includes: determining a desired amino acid profile; while producing ethanol from a plant feedstock in a process that comprises a fermentation stage, adding a reagent prior to the fermentation stage to adjust an amount of an amino acid output from the fermentation stage to match an amount of the amino acid in the desired amino acid profile; separating stillage remaining after producing the ethanol into solids and a thin stillage; and drying the solids to a comestible protein meal comprising the amount of the amino acid.
