Modification and Fiber Surface Analyses of Alkaline Peroxide Mechanical Pulp Treated with Laccase

Abstract

This paper compared the differences of laccase modified APMP and unmodified controlled trails to characterize laccase’s impacts on the whiteness, physical properties and fiber morphology of APMP. From this paper, we can see that after laccase modified, the whiteness of the APMP significantly reduced; physical properties of the APMP were reduced after the first enhanced with increasing the amount of laccase. when the amount of laccase was 2u/g, the physical properties of the APMP were best, the same time after 2u/g laccase treatment ,the surfaces of the pulp fibers engendered the devillicate and peeling.
