Enzymes are proteins that act as catalysts in the biochemical reactions of metabolism (Cooper 2000). When purified, they make it possible to carry out these reactions under controlled conditions. They can be produced from animal, plant, and microbial cells. Nevertheless, microbial enzymes stand out in large quantities and often at low cost by fermentation processes (Raveendran et al. 2018). Most enzymes produced by fermentation are associated with primary metabolism and are primarily used in the agri‐food industry to process many foods; however, more and more enzymes associated with secondary metabolism are produced for pharmaceutical purposes.
