This study assesses the influence of commercial enzyme (FibreZyme (TM) LBR) treatment applied to APMP pulp and to the mixture of 55 % Acacia CTMP75 pulp, 30 % soft-wood bleached chemical pulp (LBKP 90 from Chile) and 15 % hard-wood bleached chemical pulp (NPKP 90 from Indonesia). The treatment was conducted at different temperatures, reaction times and enzyme dosages. The APMP and mixed pulp treated with the enzyme showed a significant decrease of refining time to achieve the same refining degree (Schopper-Riegler freeness, degrees SR) and better mechanical-physical properties due to the development of fibrillation. The fibre morphology difference between before and after treatment was revealed by the microscopic observations performed by a scanning electron microscope (SEM). The SEM analysis showed that the surface of the enzyme-treated fibre had some swelling and fibrillar phenomenon that lead to strong paper properties such as tear index, tensile index and burst index.
