Abstract: The present disclosure relates to a method for simultaneously degrading lignin and cellulose and for boosting effect on the cellulase activity using a specific catalyst. Since the present disclosure allows for the preparation of sugars by degrading not only lignin but also cellulose and hemicellulose using the enzymes which were previously known only as lignin-degrading biocatalysts, it provides the advantage that the preparation of a hydrolysate as a source material for the production of biofuels or biochemicals from lignocellulosic biomass can be simplified and facilitated. As a result, the present disclosure can reduce enzyme cost and can provide improved production efficiency by simplifying the biofuel production process.
