title: The immobilization of enzyme on Eupergit® supports by covalent attachment.
abstract: A selection of the best combination of adequate immobilization support and efficient immobilization method is still a key requirement for successful application of immobilized enzymes on the industrial level. Eupergit) supports exhibit good mechanical and chemical properties and allow establishment of satisfactory hydrodynamic regime in enzyme reactors. This is a good recommendation for their wide application in enzyme immobilization after finding the most favorable immobilization method. Methods for enzyme immobilization that have been previously reported as efficient, considering the obtained activity of immobilized enzyme are presented: direct binding to polymers via their epoxy groups, binding to polymers via a spacer made from ethylene diamine/glutaraldehyde, and coupling the periodate-oxidized sugar moieties of the enzymes to the polymer beads.
