The Americal Old Corrugated Containers (AOCC) was treated with laccase. Fiber morphology, molecular weight and distribution of lignin were analyzed by scanning electron microscope (SEM) gel permeation chromatography (GPC). Through the model compound (ferulic acid) laccase, correlative mechanism for improvement wet-strength pulp laccase discussed. results showed that decreased adhered on fiber surface after While heating treatment, condensation degree adhesion area increased. In addition, when ferulic acid similar to AOCC pulp.
