WebSterilised skimmed milk is placed in a column packed with immobilised yeast lactase. The immobilised enzymes hydrolyse the lactose to form glucose and galactose and therefore produced is lactose-free milk. Another analytical test in Medicine is used to detect antibodies particular to a certain infection. WebImmobilized enzyme. 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.
