What type of enzymes are used in industry?

In addition to being essential within living organisms, enzymes are also used in many of the products we use! Check your cleaning supplies at home, do any of them list enzymes on the ingredient list? If so, does it say which type of enzyme? Does any of the other products you use contain enzymes? What type of enzymes are used in industry? Which enzymes are found in the food we eat?   

After doing some research, choose and describe one enzyme that is used in cleaning products, other products, industrial procedures or that is found in food. Explain how this enzyme is used. What is the substrate in the chemical reaction? And what is the product(s)?
