4.6 Conclusion

Enzyme immobilization is an area of active research where the recent advances in the design of immobilization support have enabled more precise control of enzyme property. Many enzymes have been successfully immobilized on many different types of organic and inorganic carriers such as alginate beads, polyaniline matrix, glass beads, microporous polypropylene hollow fiber membranes, activated carbon, chitosan film, modified microfiltration membrane and magnetic chitosan microsphere (Domínguez et al. 2007). The selection of the suitable carrier material is another big challenge in immobilization process. Immobilization onto a carrier is a costly affair due to addition of external carrier.

Chitosan is biodegradable in nature and its use is in good conformity with sustainable development. Moreover, it is abundant and its renewable nature make it an attractive and cost-effective biomaterial for the immobilization of many enzymes used in various industries. Moreover, it can replace the some cross-linkers used which are used in cross-linking of enzymes such as glutaraldehyde, due its biocompatibility makes it an environmentally harmless reactant that does not put the health of the workers at risk over glutaraldehyde. Some findings are also indicated that the stability and biodegradation capability of free fungal laccase enhanced by entrapping the enzyme within genipin-activated chitosan beads.

This chapter may be concluded with discussion that enzymes immobilized on chitin- and chitosan-based supports, as compared to unimmobilized biomolecules, has improved considerably the biocatalytic potential that has expanded applications of this versatile biomaterials ranges from biomedical to sustainable agriculture.
