The commercial pectinase (Rohapect®DA6L) from Aspergillus niger was successfully in situ immobilizedin rigid polyurethane foam (RFPU), achieving a yield of immobilization of 178.64%. The optima reactionconditions for free and immobilized pectinase were pH 3.5 and 37◦C and pH 4.5 and 55◦C, respectively.During the evaluation of storage stability of immobilized derivative at 4◦C, a hyperactivation of enzymeactivity was observed, with an increase of 98% on the initial activity after 229 days of storage. The studyof thermal stability showed that the immobilization exerted a protective effect to the enzyme submittedto high temperatures, probably due to a result of the microenvironment created inside the RFPU. Thekinetic parameters showed that the immobilization process did not change the affinity of the enzyme bythe substrate. The immobilized pectinase in RFPU was reused consecutively by 6 catalytic cycles in thehydrolysis of pectic oligosaccharides, keeping 35% of its initial activity. Due to the good performance ofthe enzymatic derivative, this presents a potential alternative to be used in the conception of industrialreactors.
