Abstract

A significant increase in delignification was obtained for both a pine kraft pulp and ail oxygen-delignified pine kraft pulp by means of HBT-mediated (1-hydroxybenzotriazole) laccase treatment compared with the reference treatments. Residual lignins from the pulps before and after the different treatments were isolated and characterized. Laccase,without mediator did nor delignify the pulp, nor did it depolymerize or polymerize the lignin in the fibres. However some minor chemical modifications occurred in the fibre lignin. On the other hand laccase together with HBT was able to degrade the lignin in the pulp fibres. HBT-mediated laccase treatment also caused an increase in the carbonyl and carboxyl group contents, and a decrease in the free phenolic hydroxyl and methoxyl group contents of the residual lignins.
