Immobilising Enzymes

AdvantagesGetting Started

Enzymes are not present with products so purifications/ downstream processing costs are low.
Enzymes are immediately available for reuse. Allows for continuous processes.
Immobilised enzymes are more stable because immobilising matrix protects enzyme molecules.

Disadvantages

Immobilistaion requires additional time, equipment and materials so is more expensive to set up.
Immobilised enzymes may be less active as they can not mix freely with the substrate.
Any contamination is costly to deal with because the whole system would need to be stopped.

Evaluation

As enzymes are used mostly in large-scale productions, costs and time issues are unlikely to be a factor. A higher yield and lower costs are produced using immobilised enzymes therefore they are more advantageous.
