Immobilization of Cellulase using Nano-Magnetic Calcium Alginate as a support

In this study, cellulase was immobilized on nano-magnetic calcium alginate beads. The effect of sodium alginate and calcium chloride concentration on the immobilization conditions was studied. It was found that the optimum sodium alginate and calcium chloride concentration was 4.0% and 0.25 M, respectively. Thermal stability of the enzyme increased after immobilization and immobilized cellulase retained more than 70% of its initial activity after 3 days at room temperature compared with free enzyme which showed only 20% of residual activity
