  • Publication number: 20130011886
    Abstract: The present invention comprises pretreating a lignocellulosic feedstock with acid at a pH between about 2.0 and about 3.5 to produce a composition comprising an acid pretreated feedstock. The acid pretreated feedstock is then enzymatically hydrolyzed with cellulases and ?-glucosidase. The glucose is fermented by microorganisms to produce a fermentation broth comprising the fermentation product, followed by recovery of the fermentation product. The steps of enzymatically hydrolyzing and fermenting are conducted at a pH below about 4.0.

  • Publication number: 20120315674
    Abstract: In one embodiment the instant invention generally pertains to a method for producing glucose for fermentation. The method comprises first treating a biomass comprising a lignocellulosic material with a mixture comprising SO2 and steam at reaction conditions sufficient to produce a composition mixture comprising cellulose suitable for enzymatic hydrolysis. Specifically, the temperature, residence time, and SO2 concentration may be selected by calculating a crystallinity index (CrI) of the biomass and using the calculated crystallinity index as an indicator of enzymatic hydrolysis rate. In this manner cellulose may be enzymatically hydrolyzed glucose for aerobic or anaerobic fermentation.

  • Publication number: 20120167456
    Abstract: Techniques, systems, apparatus and material are disclosed for generating multi-purpose H2-dense fuel for isolating contaminants and storing energy. In one aspect, a method of producing a renewable multi-purpose biomaterial for isolating a hazardous contaminant from an environment and storing energy includes dissociating biomass waste using a thermochemical reaction to produce at least one of hydrocarbon and alcohol by applying waste heat recovered from an external heat source. The method includes dissociating the at least one of hydrocarbon and alcohol to generate carbon and hydrogen. Carbon dioxide emitted from an industrial process is harvested and reacted with the hydrogen to generate the hydrogen-dense fuel. A hazardous contaminant is dissolved in the hydrogen-dense fuel operating as a solvent to generate a liquid mixture that isolates the hazardous contaminant from the environment. The hazardous contaminant includes at least one of a carbon donor and a hydrogen donor.

  • Publication number: 20120156741
    Abstract: Alcohols useful as fuel compositions are produced from biomass by pretreating the biomass prior to hydrolysis and fermentation. In the pretreatment, the biomass is contacted with an aqueous solution containing a dilute acid with concentration of up to 10 wt % producing a predigested stream containing an aqueous liquor that contains at least a portion of hemicelluloses and a residual biomass that contains celluloses and lignin; separating at least a portion of the aqueous liquor from the residual biomass providing an aqueous liquor stream and a pre-digested biomass stream; then contacting the pre-digested biomass stream with a cooking liquor containing at least one alkali selected from the group consisting of sodium hydroxide, sodium carbonate, sodium sulfide, potassium hydroxide, potassium carbonate, ammonium hydroxide, and mixtures thereof and water. A process that allows for higher recovery of carbohydrates and thereby increased yields is provided.

  • Publication number: 20120156738
    Abstract: An alcohol fermentation process and composition that includes production of alcohol esters by esterification of product alcohol in a fermentation medium with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product alcohol, such as butanol, with the carboxylic acid to form the alcohol esters. The alcohol esters can be extracted from the fermentation medium, and the product alcohol recovered from the alcohol esters. The carboxylic acid can also serve as an extractant for removal of the alcohol esters from the fermentation medium.
