Abstract
Bacterial cellulose (BC) membranes can be modified for covalent immobilization of macromolecules. One type of modification is oxidation, after which the oxidized BC membrane (OBC) could be used as a matrix for covalent immobilization of enzymes. In this work, the BC membrane was chemically oxidized with sodium periodate (NaIO4) to increase the stability of immobilized mesophilic L-asparaginase (L-ASNase) from Erwinia carotovora (EwA). IR spectroscopy confirmed the immobilization of L-ASNase EwA on OBC membranes. Immobilization of the enzyme increased its temperature optimum for its activity by 15°C and raised the inactivation temperature to 60°C. The OBC membrane could be used as a potential carrier for covalent immobilization of enzymes to improve their pharmacological properties by increasing their thermostability.
