Some types of reagents are dilute acids, cellulase enzymes, hemicellulase enzymes, Fenton or Fenton-like reagents, and hydrogen peroxide. These reagents are homogenized by mixing the reagents with process water using turbulent mixing to produce a homogeneous reagent.Type: GrantFiled: January 28, 2015Date of Patent: November 24, 2015Inventor: Edward Brian Hamrick

Publication number: 20150147786Abstract: A process for mechanical destructuring of starch-based biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured starch-based biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications. The destructured starch-based may saccharified to produce syrups and fermentable sugars, and for production of products including ethanol using a biocatalyst.Type: ApplicationFiled: November 18, 2014Publication date: May 28, 2015Inventors: KATHLEEN A CLARKSON, F Glenn Gallagher, Aaron Perelman, Luis Fernando Romero Millan, Vivek Sharma, Jayarama K.

Publication number: 20150147791Abstract: The engineering of a pathway converting CH4 to acetate and eventually to liquid fuels is disclosed. The engineered pathway involves an engineered reversal of the natural pathway for acetate conversion to CH4 by microbes and coupling the engineered pathway to existing and future technologies for microbial or chemical conversion of acetate to liquid fuels. In one aspect, methods for producing modified pathways and/or microbes are provided. In another aspect engineered microbes, including Methanosarcina acetivorans, that incorporate the engineered pathway are provided, which can mediate conversion of CH4 to acetate for ultimate conversion to liquid fuels. In a further aspect, specific modifications to the components of the pathway are provided.Type: ApplicationFiled: November 21, 2014Publication date: May 28, 2015Inventors: James Gregory Ferry, Costas D. Maranas, Thomas Keith Wood

Patent number: 9040278Abstract: An ?-amylase from Bacillus subtilis (AmyE) produces significant amounts of glucose from various carbohydrate substrates, including vegetable starch, maltoheptaose, and maltotriose. Among other things, this advantageous property allows AmyE or variants thereof to be used in a saccharification reaction having a reduced or eliminated requirement for glucoamylase. The reduction or elimination of the glucoamylase requirement significantly improves the efficiency of the production of ethanol or high fructose corn syrup, for example.Type: GrantFiled: June 4, 2009Date of Patent: May 26, 2015Assignee: DANISCO US INC.Inventors: Luis G. Cascao-Pereira, Regina Chin, William A. Cuevas, David A. Estell, Sang-Kyu Lee, Michael J. Pepsin, Scott D. Power, Sandra W. Ramer, Carol A. Requadt, Andrew Shaw, Amr R. Toppozada, Louise Wallace

Publication number: 20150139977Abstract: The invention relates to enzymes having xylanase, mannanase and/or glucanase activity, e.g., catalyzing hydrolysis of internal ?-1,4-xylosidic linkages or endo-?-1,4-glucanase linkages; and/or degrading a linear polysaccharide beta-1,4-xylan into xylose. Thus, the invention provides methods and processes for breaking down hemicellulose, which is a major component of the cell wall of plants, including methods and processes for hydrolyzing hemicelluloses in any plant or wood or wood product, wood waste, paper pulp, paper product or paper waste or byproduct. In addition, methods of designing new xylanases, mannanases and/or glucanases and methods of use thereof are also provided. The xylanases, mannanases and/or glucanases have increased activity and stability at increased pH and temperature.Type: ApplicationFiled: October 22, 2014Publication date: May 21, 2015Inventors: David Weiner, David Blum, Alexander Varvak, Shaun Healey, Kristine Chang, Geoff Hazlewood, Thomas Todaro, Grace Desantis, Hwai Chang, Connie Jo Hansen, Scott W.
