The Biobleaching Effects of Xylanase from Streptomyces griseorubens LH-3 on Bagasse Pulp

Abstract:

In this work, the S. griseorubens LH-3 crude xylanase was used to treat bagasse pulp, and the release of chromophores was the highest at the dosage of 30 IU g¹ dry pulp. Pulps, untreated and treated with crude xylanase were bleached with hydrogen peroxide. Biobleaching of bagasse pulp with this enzyme increased the brightness of the pulp by 8.5% and reduced the Kappa number by 15.3% compared with the untreated group.This crude xylanase has promising potential for industrial applications.
