What are the functions of the fermentation tank?

It is these characteristics of microorganisms that make them the masters and heroes of fermentation engineering. A fermenter is an external environmental device where microorganisms grow, multiply and form products during the fermentation process. It replaces traditional fermentation vessels – culture bottles, sauce jars and wine cellars of all kinds. Compared with the traditional container, the most obvious advantages of the fermenter are: it can carry out strict sterilization, and can make the air circulate as needed, so as to provide a good fermentation environment; it can implement stirring and shaking to promote the growth of microorganisms; it can It can automatically control temperature, pressure and air flow; it can measure the concentration of bacteria, nutrients, product concentration, etc. in the fermentation tank through various biosensors, and use a computer to adjust the fermentation process at any time. Therefore, the fermentation tank can realize large-scale continuous production, maximize the use of raw materials and equipment, and obtain high output and high efficiency. In this way, one can take full advantage of the fermentation method to produce the desired food or other product. To put it simply, fermentation engineering is a large-scale industrial production of fermented products by studying and transforming the strains of fermentation, and applying modern technical means to control the fermentation process. Protein is the main material that constitutes human tissue, and it is also a food that is very lacking on the earth. The use of fermentation engineering to produce large and rapid single-cell proteins complements the deficiencies of natural products.

Because in the fermenter, each microorganism is a protein synthesis factory. 50% to 70% of each microorganism’s body weight is protein. In this way, many “wastes” can be used to produce high-quality food. Therefore, the production of single-cell protein is one of the outstanding contributions of fermentation engineering to human beings. In addition, fermentation engineering can also manufacture lysine, which is indispensable to the human body, and many kinds of medicinal products. Our commonly used antibiotics are almost all products of fermentation engineering.
