immobilized derivative can be recovered at the end of a hydrolysis cycle and reused, as long as the enzyme remains active for several reaction cycles. Thus, enzyme immobilization and stabilization should be related terms and, in fact, a proper immobilization may improve enzyme stability via multipoint or multisubunit immobilization [10,11]. Enzyme immobilization and its application in continuous processes are desirable, as long as an end product of high purity is obtained, as is typical of enzymatic processes [12,13].Different supports can be used to immobilize an enzyme via different physical or chemical phenomena, perhaps involving different regions of the protein and yielding different orientations [14]. As has been previously described, reversible immobilization and covalent immobilization may be more or less adequate depending on the requirements [15]. The ionic exchange of a very stable enzyme on an anion exchanger (e.g., aminated supports) may provide a way of reusing the enzyme several cycles, and recover the support and reuse it again after inactivation [15]. However, if stabilization is pursued, an intense multipoint covalent attachment between the enzyme and the support should be the objective of the immobiliza-tion [10]. This strategy can produce a very high stabilization of the enzyme by reducing the mobility of the enzyme structure, although may be difficult to optimize.
