[ 1 ] - Influence of Fungal Enzyme Pre-treatment on Totally Chlorine-free (TCF) Bleaching of Dimethyl Formamid Bagasse Pulp

A study was carried out on totally chlorine-free (TCF) bleachability of dimethyl formamide (DMF) treated bagasse pulps exposed to CZ-3 and FP 90031-sp strains of white-rot fungus Ceriporiopsis subvermispora. This process involved an oxygen and peroxide stage bleaching sequence. The effect of enzymatic stage on bleachability properties was studied and compared with control pulps, processed witho...

[ 2 ] - Biobleaching of Bagasse Pulp with Xylanase Enzymes and Hydrogen Peroxide

The effect of the operating conditions (temperature, time, pH, enzyme level and pulp consistency) used in the enzymatic step of a XP (Cartazyme-hydrogen peroxide) sequence for bleaching Kraft pulp from bagasse on various properties of the resulting pulp and paper sheet products was studied. The quality of bagasse used, was examined by its yield, brightness,viscosity and the Kappa number. Finall...
