Chitin deacetylase is an enzyme that can play an important role in enzymatic deacetylation of chitosan to obtain polymers with a lower degree of acetylation. As this enzyme has never been immobilized up to now, efforts were directed towards determining both the most suitable carrier and the best method of covalent attachment to the selected carrier. In the preliminary experiments several different...
Cellulose-based carriers Granocel were specially prepared and optimised for covalent immobilization of enzymes. The effects of carrier characteristics such as pore size, chemistry of anchor groups and their density on invertase immobilization efficiency were evaluated. It was found that the preferential adsorption/binding of the enzyme to a carrier during coupling and its activity after immobilization...
