  • Publication number: 20100159516
    Abstract: Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of one or more alkylamine and optionally one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation.

  • Publication number: 20100159521
    Abstract: Methods for treating lignocellulosic biomass to produce readily saccharifiable carbohydrate-enriched biomass are provided. In one method, lignocellulosic biomass comprising lignin is treated with aqueous ammonia, then contacted with a gas comprising ozone at a temperature of about 0° C. to about 50° C. In another method, lignocellulosic biomass comprising lignin is contacted with a gas comprising ozone at a temperature of about 0° C. to about 50° C., then treated with aqueous ammonia. The readily saccharifiable carbohydrate-enriched biomass may be saccharified with an enzyme consortium to produce fermentable sugars.

  • Publication number: 20100151526
    Abstract: A process is described which uses whole cell preparations, immobilized or without immobilization, of a microorganism, including Aureobasidium pullulans, capable of forming enzymes of the group of fructosyltransferases, for catalyzing a reaction between sucrose and 6-O-protected glucose for formation of 6-O-protected sucrose, an intermediate in synthesis of trichlorogalactosucrose. 6-O-protected Sucrose is separated from high molecular weight by-products of the reaction having molecular weight of 500 daltons and more by reverse osmosis, and further purified by column chromatography.

  • Publication number: 20100143974
    Abstract: We have discovered a new method to treat biomass with alkali, for example lime. The lime and lignin was sufficiently removed from the treated biomass b> squeezing with a high pressure device to remove alkali and other potential inhibitors of the cellulase enzymes added for saccha?fication. The resulting fibrous material was rapidly solubilzed by cellulases, even at solid loads ranging from 10 to 30% (w/w) without inhibitory effects on the cellulase activity. The lime pretreatment removed lignin effectively and left the cellulose and hemicellulose almost intact. The method yielded a biomass with structure capable of being enzyme solubilzed and fermented readily at a solids loading of 10-30% for a production of ethanol.
