Commercial uses of Enzymes The use of enzymes to modify foods has increased vastly and these fermentations are continuing to be important, however, a new type of enzyme industry has evolved which involves the use of harvesting enzymes from microorganisms. The production of enzymes from bacteria and fungi can be isolated from the growth media and cleansed and purified as necessary. Generally in industrial processes the enzyme is immobilised which allows t h enzyme to be re-used and also enable the products to be separated easily. The production of textiles, paper, leather fruit juices and biological detergents are produced from Microbial enzymes. Enzymes work by breaking down a substrate into simpler molecules. They increase the rate at which a reaction occurs. They lower the activation energy, which results in a quicker rate. Once the substrate leaves the active site of the enzyme the enzyme is free to combine with another free...
