Modified Cellulase with Amphiphilic Copolymers: Solubilization in Organic Solvent

  • Conference paper
Biochemical Engineering for 2001

Abstract

Enzymatic conversion of waste cellulosic materials to sugar is a very promising process because cellulose is the most abundant renewable resource. One of the major expenses associated with this process is the high cost and consumption of cellulose [1]. In the view of enzyme, there are three important but difficult points ; the first is how to produce the active enzyme, the second is how to maintain stability of activity against reaction environment such as temperature and pH, the third is how to recover free cellulase after saccharification. In this study recovery of modified cellulase from hydrolytic residue has been performed by the extraction using water-immiscible organic solvent. Cellulase was modified with new amphiphilic copolymers of polyalkylene glycol (PAG) alkylallylether and maleic acid anhydride.
