Using cheap additives to improve the efficiency of enzymatic hydrolysis and lower the enzyme dosage proves to be an effective way to bring down the lignocellulose conversion cost. When poly-diallyl-dimethyl-ammonium chloride (polyDADMAC) was added in alkaline pretreatment of different lignocelluloses, it did not improve the delignification but significantly enhanced the succeeding enzymatic hydrolysis. The corn stover pretreated with polyDADMAC showed an increase of 18.4 % and 21.8 % in glucan and xylan digestibility, respectively. PolyDADMAC addition also increased the glucan and xylan digestibility of alkaline-pretreated switchgrass by 17.7 % and 12.1 %, respectively. For lignin-free cellulose, the glucan digestibility increased by 31 % with polyDADMAC treatment. The boost effect was because of the disruption of cellulose fiber by polyDADMAC, rather than the removal of lignin. SEM images of pretreated samples showed caustic pits on the surface by etching with polyDADMAC, which facilitated the enzyme accessibility. The crystallinity of treated samples decreased while the surface area, pore size, and pore volume increased with polyDADMAC.

使用廉价的添加剂来提高酶水解的效率并降低酶的用量被证明是降低木质纤维素转化成本的有效方法。当在不同木质纤维素的碱性预处理中加入聚二烯丙基二甲基氯化铵（polyDADMAC）时，它不能改善脱木素作用，但可以显着增强后续的酶促水解作用。用polyDADMAC预处理的玉米秸秆的葡聚糖和木聚糖消化率分别提高了18.4％和21.8％。加入PolyDADMAC还可以将碱性预处理的柳枝the的葡聚糖和木聚糖消化率分别提高17.7％和12.1％。对于不含木质素的纤维素，采用polyDADMAC处理后，葡聚糖的消化率提高了31％。增强作用是由于聚DADMAC破坏了纤维素纤维，而不是去除木质素。预处理样品的SEM图像显示，通过用polyDADMAC进行蚀刻，在表面上出现了苛刻的凹坑，从而促进了酶的可及性。聚DADMAC处理样品的结晶度降低，而表面积，孔径和孔体积却增加。
