Immobilised enzymes worksheet
WitrynaThis practical activity is a good demonstration of the use of immobilised enzymes in biotechnology. The materials give a method for producing whey from milk. Students then use immobilised enzymes to produce glucose from the ‘waste’ whey. Students use a glucose test strip to measure the amount of glucose produced. Witryna24 lut 2013 · The lower risk of product contamination with enzyme residues and low or no allergenicity are further advantages of immobilised enzymes. Methods for immobilisation are divided into three categories: adsorption on a carrier (support), encapsulation in a carrier, and cross-linking (carrier-free). General considerations …

WitrynaThe enzyme lactase converts the whey to a sweet syrup, and this enzyme can be immobilised by trapping it in calcium alginate beads. The beads are packed into a small column, over which the whey is passed. Instructions for setting up the column and treating the whey are given below. Immobilising the lactase enzyme and packing the …
