Notizen:
A commercial pectolytic enzyme preparation has been immobilized onto a nylon-polyethyleneimine copolymer, in order ot study the contribution of the pectin lyase activity inthe overall pectindegrading activitg. Optimal conditions for the immobilization process of the pectin lyase activity, such as chemical modification of the support, coupling pH and protein concentration, were determined.Kinetic parameters and temperature behaviour of both the soluble and immobilzied pectin lyase activitgy of the derivative were also determined. OPerational stability of the pectin lyase and overall viscosity reducring activities resulting in a halflife times of 3.8 and 8.5 days, respectively, for both pectolytic activities, when the immobilized derivatives were tested in a cross-flow reactor, using a highly esterified pedtin as substrate.
