摘要
研究了几种高分子材料对纤维素酶水解作用的影响,强聚阳离子(PⅠ、PⅡ)、中强聚阴离子(PⅢ)高分子材料能促进酶的糖化作用,而强聚阴离子(PⅣ)高分子材料则不能,添加PⅠ(1.3×10^(-1)mol/L)、PⅡ(1.3×10~3mol/L)、PⅢ(1.3×10~2mol/L)分别使纤维素酶棉花糖化力提高190％、45％、75％,初步探讨了高分子材料促进纤维素酶糖化力的机理。
The effect of several synthesized macromolecules on the saccharification of cellulase was researched. Strong polypositive ion (PⅠ, P Ⅱ) , moderately polynegative ion (PⅢ) macromolecules could enhance the saccharification. But strong polynegative ion (PⅣ) macromolecules could not. PⅠ (1. 3×10-1 mol/L), PE (1. 3×10-3 mol/L) and PI (1. 3×1 0-2 mol/L) made the saccharification of cellulase increased by 190%, 45%, 75% respectively. The mechanism of enhancement of saccharification by macromolecules was researched from the view point--the effects of macro-molecules on the activity of each component of cellulase and the adsorption amount of enzyme on the substrate.
