The use of rennet in cheese manufacture was among the earliest applications of exogenous enzymes in food processing, dating back to approximately 6000 B C. In 1994, the total production of cheese was 8000 metric tons against a total demand of 9000 metric tons.
These enzymes are extracted in a lab to make microbial rennet. Microbial rennet is not widely used because it doesn't yield consistent results. It is tricky to use during the cheesemaking process, and cheese made from microbial rennet can develop unpleasant flavors. Microbial rennet can be genetically modified. To make genetically engineered rennet, chymosin chromosomes are extracted from an animal's stomach cells then implanted into yeast cultures that act as a host.
