Immobilization of Enzymes
An immobilized enzyme is an enzyme which is attached to an inert, insoluble material such as sodium alginate. This can provide increased resistance to changes in conditions such as pH or temperature.It also allows enzymes to be held in place throughout the reaction, following which they are easily separated from the products and may be used again.
