WitrynaAlso immobilised enzymes are more stable and less susceptible to having their activity reduced by pH and temperature change. The main methods of enzyme immobilisation are: 1. Entrapping the enzyme molecules in alginate balls or a network of cellulose fibres. 2. Adsorption – sticking the enzymes to porous beads of clay, resin or glass. 3 An immobilized enzyme is an enzyme, with restricted mobility, 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. It also lets enzymes be held in place throughout the reaction, foll…
