    Abstract: Saccharification of polysaccharides of plants is provided, where release of fermentable sugars from cellulose is obtained by adding plant tissue composition. Production of glucose is obtained without the need to add additional ?-glucosidase. Adding plant tissue composition to a process using a cellulose degrading composition to degrade cellulose results in an increase in the production of fermentable sugars compared to a process in which plant tissue composition is not added. Using plant tissue composition in a process using a cellulose degrading enzyme composition to degrade cellulose results in decrease in the amount of cellulose degrading enzyme composition or exogenously applied cellulase required to produce fermentable sugars.

  • Patent number: 8569018
    Abstract: The inventive process converts cellulosic biomass into a gel-like state that is readily hydrolyzed by appropriate enzymes. First the biomass is mechanically reduced in size. The biomass is then mixed and kneaded with an aqueous solution of a hydrophilic polymer that acts as a conditioning agent or as a co-solvent. During mixing the cellulose (and hemicellulose) in the biomass swells and becomes hydrated forming a viscous gel-like material. The processed material can then be thinned through the addition of water whereupon hydrolytic enzymes are mixed into the material and rapid hydrolysis into free sugars takes place. Dextrins are effective hydrophilic polymers for conditioning biomass. Polyvinyl alcohol is a particularly effective conditioning agent for use with biomass when converted into a viscous gel by adding borate ions.

  • Patent number: 8546109
    Abstract: The present invention relates to a method for lignocellulosic conversion to sugar using an ionic liquid pretreatment for the saccharification of lignocellulosic biomass. Thus, cellulose, hemicellulose, when hydrolyzed into their sugars, can be converted to ethanol fuel through well-established fermentation technologies. These sugars also form the feedstocks for production of a variety of chemical and polymers. The complex structure of the biomass required pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars.

  • Publication number: 20130252283
    Abstract: Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce ethanol. Biomass feedstock is saccharified in a vessel by operation of a jet mixer, the vessel also containing a fluid medium and a saccharifying agent.

  • Publication number: 20130244284
    Abstract: Solid biomass having a moisture content in a range of 30 to 95 mass % is brought into contact with ammonia gas at a pressure in a range of 0.5 to 4 MPa and held at 50 to 200 degrees C. Subsequently, the solid biomass is rapidly decompressed to be blasted. The ammonia gas evaporated by decompression is recovered and recycled. The ammonia gas can be brought into contact with the entire solid biomass evenly and in a short time. Since absorption heat of the ammonia gas is generated, energy consumption required for additional heating can be reduced.

  • Patent number: 8530222
    Abstract: Problem: To provide a microorganism with an ability to produce deoxy polyol dehydrogenase. Means for Resolution: A microorganism belonging to genus Enterobacter with an ability to produce a dehydrogenase for deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol. The bacterial cell IK7 of the genus Enterobacter (accession No. NITE P-271). A method for producing deoxy ketose comprising allowing a culture containing the deoxy polyol dehydrogenase obtained by the culturing of the microorganism of the invention or allowing the deoxy polyol dehydrogenase to react with a solution containing deoxy polyol of the same structure at the positions C2 and C3 as that of ribitol or L-iditol to oxidize deoxy polyol to produce the corresponding deoxy ketose and then collecting the deoxy ketose. The deoxy polyol is 1-deoxy-D-allitol, while the corresponding deoxy ketose is 1-deoxy-L-psicose.
