Immobilized enzymes are used today in various industrial technologies, and further widespread application may by expected in the years to come. An essential precondition to this is to compare methods described in the literature for a given enzyme and recently developed immobilization techniques from aspects of economic efficiency. Comparison may be drawn on the basis of results reported in scientific papers. The study of various immobilized enzymes led to the conclusion that only material expenses can be accepted as comparative fundamental data. On the basis of this, immobilized enzymes may be described by calculation and comparison of the following three characteristic values: 1. Specific material costs of immobilization; 2. initial productivity of unit volume of the reactor, or total product formation of the immobilized enzyme applied for one half‐life; 3. costs of enzymes in unit product formation. Applicability of the method is presented in the evaluation of amyloglucosidase enzymes.
