Abstract: 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^-1mol/L), PE (1. 3×10^-3mol/L) and PI (1. 3×10^-2mol/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.
