| Abstract: | The strategy of enzyme immobilization is studied with the objective of producing more stable biocatalysts that can be used in reactions of high industrial interest. Lipase B from Candida antarctica (CALB) has been covalently immobilized on epoxy Immobead-350 (IB-350) and some properties have been compared to glyoxyl-agarose-CALB and Novozym 435. The thermal and solvent stability was higher than that of the glyoxyl-agarose-CALB, and the CALB-IB350 preparation was more stable at pH 5,0 and 70 °C (t1⁄2 = 68 min). The activity of the new preparation versus tributyrin and triacetin was about 4 and 17 fold higher than that of Novozym 435, respectively. Thus, the covalent attachment between enzyme and support produced a stable and active biocatalyst under different conditions and substrates. |
