The effect of ultrafiltered xylanase-pectinase concoction produced simultaneously by a bacterial isolate using agro-waste-based media was assessed in prebleaching plywood waste pulp. Ultrafiltered enzymes caused 12.5% reduction kappa number at reduced enzyme dose (4.0-0.8 IU) per gram pulp under optimized conditions pH 8.5, temperature 55 °C, and treatment period 2 h. Using this methodology, amount Cl2-ClO2 consumption can be up to 30 28.86%. Significant improvement physical optical properties obtained along with an additional BOD COD values 18.13 21.66% novel biodelignification approach. This is the first report showing advantages over crude enhancing bleaching capacity study focussing on development good quality paper less pollution generating strategy will definitely prove boon for industries.
