【 摘 要 】

A new method for enhancing rates of enzymatic hydrolysis for cellulosic fiber is presented.By adding a cationic polyelectrolyte to a cellulase/cellulose hydrolytic system, the polyelectrolyte binds to the cellulase and fiber forming flocs.The cellulase is bound by a patching mechanism.By using this technique, the rate of enzymatic hydrolysis can be enhanced.This thesis covered observations made about the cellulase/cationic polyelectrolyte/fiber interactions.A mechanism was proposed based on the experimental results.
