A study of different actions of glucanases to modulate microfibrillated cellulose properties

Abstract Glucanases provide an excellent option for pre-treatment of cellulose and improvement in properties microfibrillated cellulose. In our research, we have used two different enzyme formulations, a purified β-1,4-endoglucanase, β-1,4-exoglucanase rich mixture the focus study is on effect high protein applications PFI refined-microfibrillated (2,500 rev). At applications, fibers showed improved fibrillation after endoglucanase treatment with 20.4% over PFI-only refined while exoglucanase mix 6.8% improvement. low resulted tensile, compression, Scott ply bond, extensional stiffness compared or untreated fibers. Ply Bond measurements are indicator hydroxyl groups fiber surface whose value increased pre-treatment. Mechanical changed suggest bonding between increases providing functionalization.
