Enzymes are bio-catalysts which effect transformation of substrates to products with high specificity. The usage of enzymes in domestic and industrial applications is well known and has been well documented since the early history of civilization. With the advances in understanding of enzymology, usage of enzymes in industrial and biotechnological pro- cesses and molecular medicine has proliferated. One of the key factors in the widespread application of enzymes in modern technologies is the development of enzyme immobilization tech- niques, which overcome certain practical, functional and...
