The process parameters for xylanase biobleaching of mixed hardwood pulp like, reaction time (6-35 h), pulp consistency (2.5-15%) and xylanase dose (5-35 U) were optimized using OFAT approach and hybrid statistical tools viz. GA-ANN and GA-ANFIS. The biobleaching ability of xylanase in terms of reducing sugar yield increased up to 28.16 mg g (28.05%) than OFAT optimization (21.99 mg g of pulp) after employing hybrid statistical tools. After TCF bleaching of xylanase treated pulp, we observed that lignin content reduced to 0.29% whereas it was still 0.41% in the untreated pulp. Moreover, the brightness level achieved up to 70.4% in xylanase treated pulp while it was only 53.60% in the chemically treated pulp. The kappa number for xylanase treated, chemically treated, and xylanase-chemical treated pulp was recorded 9.90, 7.10 and 4.70, respectively. The present study reports an improved eco-friendly biobleaching method using novel GA-ANN and GA-ANFIS hybrid statistical tools.
使用 OFAT 方法和混合统计工具（GA-ANN 和 GA-ANFIS）对类似混合硬木浆的木聚糖酶生物漂白的过程参数（反应时间（6-35 小时）、纸浆浓度（2.5-15%）和木聚糖酶剂量（5-35U）进行了优化。与 OFAT 优化（21.99mg/g 纸浆）相比，在使用混合统计工具后，木聚糖酶的生物漂白能力在还原糖产率方面提高了 28.16mg/g（28.05%）。在木聚糖酶处理的纸浆进行 TCF 漂白后，我们观察到木质素含量降低到 0.29%，而未处理的纸浆中木质素含量仍为 0.41%。此外，木聚糖酶处理的纸浆的亮度水平达到 70.4%，而化学处理的纸浆仅为 53.60%。木聚糖酶处理、化学处理和木聚糖酶-化学处理的纸浆的卡伯值分别为 9.90、7.10 和 4.70。本研究报告了一种使用新型 GA-ANN 和 GA-ANFIS 混合统计工具改进的环保生物漂白方法。
