For the immobilization matrices we revealed the binding site with the inulinase.
Ion exchange resins and fibers were experimentally tested.
The maximal affinity to the inulinase was possessed by the matrix of KU-2.
Affinities were in good agreement with catalytic activity of immobilized inulinase.
Correlation factors are −0.84 (for yeast inulinase) and −0.81 (for plant inulinase).
