Effect of xylanase treatment on properties of alkaline peroxide mechanical pulp from poplar (Populus nigra) wood

The aim of present study was to investigate the effects of xylanase enzyme obtained from Trichoderma viride on APMP pulp from Populus nigra wood. Treatment temperature, time, enzyme dosage and pulp consistency were varied. The results demonstrated that treating by xylanase has considerable effects o...
