Since the 1980s, Precision Fermentation has become a proven commercial technology.

Scientists have been using genetic engineering to program micro-organisms to produce essential products such as human insulin, enzymes such as rennet to produce cheese, as well as many other products we see on the market today. A number of vitamins and supplements on the market are also produced almost exclusively using Precision Fermentation. More recently, the process is being used to make collagen. 

Today, these products generate revenues of more than $100bn worldwide every year.
