A new biobleaching sequence for kenaf pulp: Influence of the chemical nature of the mediator and thermogravimetric analysis of the pulp

► We report a novel laccase-mediator treatment for kenaf pulp biobleaching. ► Relevance of phenoxy radicals formed in the enzymatic stage. ► Kenaf increases oxidative efficiency of laccase. ► Thermogravimetric analysis realizes cellulose surface changes.
