Abstract: front page image
(EN)Disclosed are methods and systems for treating cellulose to make it more accessible for enzymatic or chemical modification. The invention includes treating cellulose with an alkali in an alcohol/water co-solvent system. The treatment decrystallizes or deaggregates the cellulosic material. The methods and systems increase the efficiency of enzymatic or chemical modifications of cellulose for use as biofuels or cellulose derivatives.
