Application of Feruloyl Esterase in Wheat Straw Pulp Bleaching

Abstract

The pulp made from wheat straw fiber contains considerable natural cellulose, but there are more carbohydrate-ferulic acid ester-lignin cross-linking structure in the pulp. this cross-linking structure seriously hinders the recognition and binding of hemicellulase and substrate, thus affecting the efficiency of hemicellulose degradation. Feruloyl esterase, as one of hemicellulose degradation enzymes, can hydrolyze hemicellulose side chain branches. Make the plant grid structure loose, it is more important that it can enhance the accessibility of xylanase to the xylan trunk. Therefore, it is of great significance to apply it to the synergistic xylanase-assisted bleaching of wheat straw pulp.
