20080220125 | Method of Preparing More Digestible Animal Feed - Disclosed herein are methods of treating an edible fiber source to make an animal feed with increased digestible energy. An exemplary method includes hydrolyzing the edible fiber source with an inorganic fiber hydrolyzing agent in a twin screw mixer that shears the edible fiber to a size of between 0.5 to 25 mm. The hydrolysis in the mixer occurs at pressure of about 14 psig or higher with a temperature about 100° C. to 110° C. The inorganic hydrolysis liberates a first portion of soluble carbohydrates from the edible fiber source. The inorganically hydrolyzed material is also treated (before or after) with a fiber degrading enzyme to solubilize a second portion of carbohydrates. The dually hydrolyzed material is dried to form an animal feed or feed ingredient having a soluble and insoluble carbohydrate fraction with the amount of soluble carbohydrate being at least 45% wt/wt of the total carbohydrates obtained from the edible fiber source. | 09-11-2008 |
20080254524 | Increased Ethanol Production from Xylose - Methods and compositions for the production of ethanol from lignocellulosic starting materials are provided herein. Embodiments of the invention provide methods of manipulating the carbon flux of a host cell transformed with plasmids of the invention. Plasmids of the invention may include nucleotides that encode pyruvate decarboxylase. In one embodiment, a strain of the thermotolerant yeast | 10-16-2008 |
20090029432 | DRY FRACTIONATION OF CORN - Novel grain processing methods and the products obtained therefrom are disclosed. Methods may include separation of pericarp fractions, hydrolysis of the pericarp fractions one or more time, and fractionation of the hydrolyzed pericarp fractions. Hydrolyzed pericarp fractions have applications including fermentation media, livestock feed, and fuel feedstocks. | 01-29-2009 |
20090130257 | PROCESS FOR THE PRODUCTION OF ANIMAL FEED AND ETHANOL AND NOVEL ANIMAL FEED - A method for the production of ethanol and a modified animal feed is provided. The method replaces the starch in known corn-based animal feed with biomass fiber treated to make it more digestible by animals. The process includes wherein the pericarp and germ are removed from the corn kernel and processed for by-products. The starch and protein are also removed and separated. The starch is then fermented and distilled to ethanol and stillage. The bioavailable modified animal feed comprises the pericarp and germ removed from corn kernels and optionally by-products of the pericarp and germ processing, and lignocellulosic materials. The modified animal feed may optionally include energy materials such as animal and vegetable fats, vegetable soapstocks, or glycerin, and combinations thereof. | 05-21-2009 |
