ABSTRACT

Enzymes, which are very efcient and advantageous catalysts, can catalyze specic reactions under mild conditions, that is, in neutral aqueous solutions at room temperature and atmospheric pressure. However, when using organic solvents or high temperatures, the aforementioned advantages turn into disadvantages. One of the approaches of preparing more superior biocatalysts for these and other applications is enzyme immobilization. This answers part of the question of why enzymes are sometimes immobilized. The use of immobilized enzymes can lead to easier purication of the product. Another reason concerns the running and investment costs, which if lowered can provide the design of a more efcient process.
