Immobilization is important to maintain constant environmental conditions in order to protect the enzyme against changes in pH, temperature and ionic strength. These factors are very important for enhancing the enzyme stability. Moreover, immobilized enzymes can be more easily separated from substrates and reaction products and used repeatedly
Immobilized invertase on celite could retain its activity without any loss after 20 reaction cycles. No loss in activity of the invertase immobilized on polyacrylamide was observed after 18 reaction cycles. However, only a 2.85% decline of its activity was detected after 20 reaction cycles

As reported in several studies, enzyme activity is increased following the immobilization step onto a carrier. For example, laccase thermal stability was improved after immobilization onto nylon 6 nanofibers. The storage stability of laccase is enhanced upon immobilization. The residual activity of laccase immobilized on nanofibers was about 29% after seven cycles of batch operation. Reusability is an advantageous property for the continuous use of this enzyme in industrial applications.
