define enzyme immobilisation
An immobilized enzyme is an enzyme that is attached to an inert, insoluble material such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride).This can provide increased resistance to changes in conditions such as pH or temperature. Economy: The immobilized enzyme is easily removed from the reaction making it easy to recycle the biocatalyst. 2  This is particularly useful in processes such as the production of Lactose Free Milk, as the milk can be drained from a container leaving the enzyme (Lactase) inside ready for the next batch.
