Enzymes have found widespread use in industrial and analytical processes and the products of whole cell metabolism are increasingly important. It has been found useful in a number of processes to employ enzymes or even whole cells in immobilised forms. The enzymes or cells are encapsulated and the raw materials passed over them, the products can then be collected continuously. This kit illustrates the basic principles of the preparation and use of immobilised biocatalysts.

Experiments include:

• Entrapment of yeast cells and their use in fermentation
• Immobilised glucose isomerase - application in the sweetener industry
• Preparation and use of immobilised invertase

The kit contains:

• Bakers Yeast
• Invertase 'Bioinvert'
• Fructose
• Sodium Alginate
• Amberlite Resin
• Immobilised Glucose Isomerase
• Calcium Chloride
• Sodium Chloride
• Glutaraldehyde
• Buffer Solution - pH4.5
• Glucose Testing Strips

Sufficient materials for 10 students/ student groups.
