20110247609 | METHODS OF TREATING A BIOMASS FOR ENZYMATIC HYDROLYSIS - The present invention is a process for treating a feedstock comprising holocellulose. The process comprises mixing the feedstock with a solution comprising cellulose binding domains to form a mixture. The mixture is then subjected to conditions sufficient to reduce the crystallinity of holocellulose. Subsequent enzymatic hydrolysis may show an improved rate and/or fermentable sugar yield as compared to processes which do not employ the process. | 10-13-2011 |
