METHOD FOR THE PREPARATION OF CARBOHYDRATE CLEAVAGE PRODUCTS FROM A LIGNOCELLULOSIC MATARIAL

摘要

A method for the preparation of carbohydrate cleavage products, characterized by the combination of the measures that the lignocellulosic material is treated with an aqueous solution containing hydrogen peroxide, an alcohol, in particular a C1-4 alcohol or a phenol, and a base in order to oxidatively break down lignocellulose and to separate cleavage products from the material, and that the obtained material enriched with cellulose and hemicelluloses is treated with a carbohydrate-cleavage enzyme in order to prepare the carbohydrate cleavage products.
