IMPROVEMENT OF CELLULASE ACTIVITY WITH AMPHIPHILIC LIGNIN DERIVATIVE

摘要

An effective cellulase-aid agent has to be developed to establish an efficient saccharification system for bioethanol production from huge piles of unused, lignocellulosic biomass. We have successfully developed some types of lignin derivatives that enhance the efficiency of enzymatic hydrolysis of unbleached pulp with cellulase and help to maintain its original activity after repeated use. These cellulase-aid agents were prepared by the conversion of acetic acid lignin into amphiphilic derivatives with polyethylene glycol-related compounds.
