The brightness of bleached ethanol-soda pulp of <em>E. binata</em> increased by 3.2 and 1.9% (ISO) with <em>A. flavus</em> ARC-12 and <em>S. commune</em> 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 <em>A. flavus</em> ARC-12 and <em>S. commune</em> ARC-11 xylanase pretreatment respectively. Moreover, <em>A. flavus</em> ARC-12 and <em>S. commune</em> ARC-11 xylanase pretreatment reduced AOX generation by 23.80 and 19.04% respectively compared to chemical bleaching.</h4> ER -
