| 20100143974 | Process for Sugar Production from Lignocellulosic Biomass Using Alkali Pretreatment - 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 sacchaπfication. 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. | 06-10-2010 |
