20090053770 | Biomass Pretreatment - A method is provided for producing an improved pretreated biomass product for use in saccharification followed by fermentation to produce a target chemical that includes removal of saccharification and or fermentation inhibitors from the pretreated biomass product. Specifically, the pretreated biomass product derived from using the present method has fewer inhibitors of saccharification and/or fermentation without a loss in sugar content. | 02-26-2009 |
20090053777 | Process For Concentrated Biomass Saccharification - Processes for saccharification of pretreated biomass to obtain high concentrations of fermentable sugars are provided. Specifically, a process was developed that uses a fed batch approach with particle size reduction to provide a high dry weight of biomass content enzymatic saccharification reaction, which produces a high sugars concentration hydrolysate, using a low cost reactor system. | 02-26-2009 |
20120102823 | PRODUCTION OF HIGH SOLIDS SYRUP FROM LIGNOCELLULOSIC BIOMASS HYDROLYSATE FERMENTATION BROTH - Lignocellulosic biomass hydrolysate fermentation broth may be processed to produce a high solids syrup having relatively low viscosity that has a high energy content and may be burned in a fermentation production process. The high solids syrup was achieved through liquid/solid separation of broth or depleted broth producing a thin stillage with low suspended solids allowing evaporation to high solids while maintaining low viscosity. | 05-03-2012 |
20120178976 | PROCESS FOR LIQUID/SOLID SEPARATION OF LIGNOCELLULOSIC BIOMASS HYDROLYSATE FERMENTATION BROTH - When lignocellulosic biomass hydrolysate is included in fermentation medium, the broth resulting from biocatalyst production is complex with low filterability. A heat treatment was found to increase filterability, allowing efficient separation of a liquid fraction from a solid fraction, which is further processed for water recycle and syrup production. | 07-12-2012 |
20130157316 | INCREASED POLY (ALPHA 1,3 GLUCAN) YIELD USING BORIC ACID - A process for production of poly(α1,3 glucan) from a renewable feedstock, for applications in fibers, films, and pulps. The effect of addition of boric acid in increasing the yield of the desired end products, poly(α1,3 glucan) and fructose, and decreasing formation of the undesired by-product leucrose. | 06-20-2013 |
20130196384 | INCREASED POLY (ALPHA 1,3 GLUCAN) YIELD USING TETRABORATE - A process for production of poly (α 1,3 glucan) from a renewable feedstock, for applications in fibers, films, and pulps. The effect of addition of tetraborate in increasing the yield of the desired end products, poly (α 1,3 glucan) and fructose, and decreasing formation of the undesired by-product leucrose. | 08-01-2013 |
20150064748 | PROCESS FOR PRODUCING APLHA-1,3-GLUCAN POLYMER WITH REDUCED MOLECULAR WEIGHT - A process for producing poly alpha-1,3-glucan with reduced molecular weight is disclosed. The process comprises contacting water, sucrose, a polar organic solvent, and a glucosyltransferase enzyme in a solution to produce poly alpha-1,3-glucan. This contacting step results in the production of poly alpha-1,3-glucan having a reduced molecular weight compared to the molecular weight of a poly alpha-1,3-glucan made in the absence of the polar organic solvent. | 03-05-2015 |
20150240278 | ENZYMATIC HYDROLYSIS OF DISACCHARIDES AND OLIGOSACCHARIDES USING ALPHA-GLUCOSIDASE ENZYMES - A method is disclosed for hydrolyzing an alpha-1,5 glucosyl-fructose linkage in a saccharide (disaccharide or oligosaccharide) such as leucrose. This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase or glucoamylase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,5 glucosyl-fructose linkage of the saccharide. This method is useful for reducing the amount of leucrose in a filtrate isolated from a glucan synthesis reaction, for example. | 08-27-2015 |
20150240279 | ENZYMATIC HYDROLYSIS OF DISACCHARIDES AND OLIGOSACCHARIDES USING ALPHA-GLUCOSIDASE ENZYMES - A method is disclosed for hydrolyzing an alpha-1,3 or alpha-1,6 glucosyl-glucose linkage in a saccharide (disaccharide or oligosaccharide). This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,3 or alpha-1,6 glucosyl-glucose linkage of the saccharide. This method is useful for reducing the amount of oligosaccharides in a filtrate isolated from a glucan synthesis reaction, for example. | 08-27-2015 |
