  • Patent number: 8067204
    Abstract: A method for producing a chondroitin sugar chain comprises reacting a glucuronic acid donor, an N-acetyl galactosamine donor, a sugar receptor and a bacterial cell enzyme which synthesizes chondroitin in the presence of a surfactant. The surfactant is selected from polyoxyethylene octadecyl amine, n-decanoyl-N-methylglucamide, sodium cholate, n-octyl-?-D-thioglucopyranoside, n-nonyl-?-D-thiomaltopyranoside, sucrose monocholate, sucrose monocaprate, and sucrose monolaurate. The chondroitin sugar chain has all the following properties: a weight average molecular weight: 50,000 or more when measured by gel filtration chromatography; it is completely degraded to disaccharides with chondroitinase ABC; and when the sugar chain is decomposed with chondroitinase ABC and the decomposed products are subjected to a disaccharide analysis, substantially all of them correspond to an unsaturated disaccharide unit of chondroitin.

  • Patent number: 8030030
    Abstract: A method for lignocellulose conversion to sugar with improvements in yield and rate of sugar production has been developed by using ionic liquid pretreatment. This new pretreatment strategy substantially improves the efficiency (in terms of yield and reaction rates) of saccharification of lignocellulosic biomass. Cellulose and hemicellulose, when hydrolyzed into their sugars, can be converted into ethanol fuel through well established fermentation technologies. These sugars also form the feedstocks for production of variety of chemicals and polymers. The complex structure of biomass requires proper pretreatment to enable efficient saccharification of cellulose and hemicellulose components to their constituent sugars. Current pretreatment approaches suffer from slow reaction rates of cellulose hydrolysis (by using the enzyme cellulase) and low yields.

  • Patent number: 7968123
    Abstract: The invention provides a composition containing particulate composite of a polymer and a therapeutic agent. The composition also contains a complexing agent. The polymer interacts with the complexing agent in a host-guest or a guest-host interaction to form an inclusion complex. A therapeutic composition of the invention may be used to deliver the therapeutic agent and to treat various disorders. Both the polymer of the particulate composite and the complexing agent may be used to introduce functionality into the therapeutic composition. The invention also relates to a method of preparing a composition. The method combines a therapeutic agent, a polymer having host or guest functionality, and a complexing agent having guest or host functionality to form the therapeutic composition. The complexing agent forms an inclusion complex with the polymer. The invention also relates to a method of delivering a therapeutic agent.

  • Publication number: 20110143398
    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.

  • Publication number: 20110136176
    Abstract: A method for treating a lignocellulose raw material so as to facilitate a pulverization treatment that is necessary for the efficient and effective use of a lignocellulose raw material as a raw material or resource for material conversion. When converting a lignocellulose raw material into sugar or a useful material, such as ethanol, with the aid of an enzyme or producing a biodegradable material derived from a lignocellulose raw material via a mechanical or chemical treatment, a lignocellulose raw material is treated with an enzyme prior to or simultaneously with the pulverization process, so that the viscosity of slurry comprising a lignocellulose raw material and water is lowered and the pulverization efficiency is improved.

  • Publication number: 20110129881
    Abstract: The invention relates to recombinant expression of a variant form of a fungal C1 strain ?-glucosidase. The invention also relates to the generation of fermentable sugars from biomass and the production of biofuels by fermentation of the sugars using genetically modified organisms expressing the ?-glucosidase variant. The invention provides methods for producing a fermentable sugar, such as glucose, from cellobiose by contacting cellobiose with a recombinant ?-glucosidase variant protein, such as a variant protein secreted by a recombinant host cell into culture medium. Methods of the invention may be used for conversion of a biomass substrate to a fermentable sugar, and ultimately to ethanol or other biofuel.
