  • Title: Optimization of covalent immobilization of pectinase on sodium alginate support.
    Author: Li T, Wang N, Li S, Zhao Q, Guo M, Zhang C.
    Journal: Biotechnol Lett; 2007 Sep; 29(9):1413-6. PubMed ID: 17541760.
    Abstract:
    Pectinase was immobilized on a sodium alginate support using glutaraldehyde and retained 66% activity. The optimal pH for activity shifted from 3.0 to 3.5 after immobilization; however, the optimum temperature remained unchanged at 40 degrees C. The immobilized enzyme also had a higher thermal stability and reusability than the free enzyme, and retained 80% of initial activity after 11 batch reactions.
