The heterogeneous biocatalyst based on inulinasе immobilized on the non-ionogenic sorbent of Stirosorb was proposed. Investigation of thermic and acid inactivation of free and immobilized inulinasе was carried out. The corresponding values of the inactivation constants were rated. Increase of thermal stability of the immobilized ferment compared to the free one was exposed. Possibility of use of the immobilized ferment ten cycles long during the reaction of inulin hydrolysis was determined.
