Environmental pollution can be minimized by using xylanase pretreatment of pulp before chemical bleaching. A. flavus ARC-12 and S. commune ARC-11 produced 234.26 and 1147.11 IU/ml of xylanase under solid-state fermentation that was used for biobleaching of ethanol-soda pulp of Eulaliopsis binata. The brightness of bleached ethanol-soda pulp of E. binata increased by 3.2 and 1.9% (ISO) with A. flavus ARC-12 and S. commune ARC-11 xylanase respectively compared chemical bleaching at the same chlorine dioxide charge. While the consumption of chlorine dioxide were mitigated by 2.98 and 3.82% with A. flavus ARC-12 and S. commune ARC-11 xylanase pretreatment respectively. Moreover, A. flavus ARC-12 and S. commune ARC-11 xylanase pretreatment reduced AOX generation by 23.80 and 19.04% respectively compared to chemical bleaching.Downloads
