Introduction to the production methods of enzymes.

is a process in which the enzymes needed are pre-designed and manually controlled. In a nutscape, there are three methods of enzyme production: extraction, fermentation and chemical synthesis.
(i) extraction method
extraction method is the earliest and has been used to date a method. Extraction uses a variety of techniques to extract enzymes directly from
or
cells or
tissues
plants or microorganisms. Although the extraction method is simple and easy, it must have sufficient raw materials, which restricts the wide application of the extraction method. However, in areas rich in animal and plant or microbial resources, extraction is still of applied value. For example, in slaughterhouses, trypsin can be extracted from the pancreas of livestock, and in fruit processing plants, pineapple
proteases can be extracted from
.
(ii) Fermentation method
method is the main method of producing enzymes since the 1950s. Fermentation method mainly through microbial fermentation to obtain the enzymes that people need. Fermentation method generally includes solid fermentation, liquid deep fermentation, fixed cell fermentation and protophysic fermentation.
(iii) Chemical Synthesis
chemical synthesis is a technique for the production of enzymes that emerged in the late 1960s. In 1969, U.S. scientists first used chemical synthesis to obtain a nucleic acid

acids. However, chemical synthesis is expensive and can only synthesize enzymes with known chemical structures. Therefore, the chemical synthesis method is still in the laboratory synthesis stage.
