Immobilized enzyme reactors (IMERs) produced by the covalent attachment of ribonuclease A to macroporous
methacrylate-based monolithic supports using different experimental approaches are discussed and compared. Enzyme immobilization was carried out by direct covalent binding, as well as through attachment via a polymer spacer. The kinetic properties of an IMER operating in either recirculation mode or zonal elution mode were studied. Additionally, the effect of flow rate on the bioconversion efficiency of each IMER sample was examined.
