摘要: 以预处理后的废纸脱墨浆为底物,纤维素酶和纤维二糖酶为水解酶,研究了不同预处理方法(包括Na2SO3、H2O2、HCl)对酶解得率的影响。结果表明:与原料相比,3种预处理方法都不同程度地提高了纤维素含量,增加底物的比表面积,降低纤维素的结晶度,促进酶水解;其中,H2O2预处理后的废纸脱墨浆的酶解得率最高,为91.67%,其次是亚硫酸钠预处理和盐酸预处理,得率分别为87.57%和82.49%。

关键词: 废纸脱墨浆, 预处理, 酶水解, 表面积, 结晶度

Abstract: In order to study the effects of various pretreatments(Na2SO3, H2O2 and HCl) on enzymatic hydrolysis of deinking waste paper pulp, the hydrolyses were carried out with the pretreated pulp as substrate and cellulase and cellobiase as hydrolytic enzyme.It was concluded that three pretreatment methods could increase glucose yield by improving the content of cellulose, inceasing the specific area and disrupting its structure.Compared with the yield of raw pulp, the highest yield was achieved with the hydrolysis of hydrogen peroxide pretreated deinking waste paper pulp (91.67%), closely followed by sodium sulfite (87.57%) and dilute acid pretreatment (82.49%).

Key words: deinking waste paper pulp, pretreatment, enzymatic hydrolysis, surface area, crystallinity
