Hydroxycinnamic acids, which were released from lignin subunits by the activity of feruloyl esterase, were used as a natural mediator of laccase. The use of sequentially feruloyl esterase and laccase has much higher pulp bleaching effects than the individual enzymes. GthFAE, BmegLac and GthFAE+BmegLac treatments (X) reduced the kappa number of eucalyptus kraft pulps by indicating 9%, 18%, and 30% delignification rates, respectively. Just like in delignification rates, the highest brightness improvement was achieved from the GthFAE+BmegLac combination. The results of the present study indicated that the natural mediators, which are presented in the structure of lignin, could be used as laccase-mediators for pulp bleaching more efficiently and cost-effectively.</description> </descriptions> </resource>
