Exploration of a three-dimensional matrix as micro-reactor in the form of reactive polyaminosaccharide hydrogel beads using multipoint covalent interaction approach.

(256 mM) values as compared to soluble enzyme version. Thermal stability of the crosslinked dextransucrase also particularly improved 2.5 fold at 45 °C in comparison with soluble enzyme. Improved catalytic performance suggests that multipoint covalent immobilization protocol adapted using hydrogel system could be tailored as microreactor for catalysis of profitable macromolecules.
