Fermentation characteristics

1. Generally speaking, the fermentation process is a biochemical reaction at normal temperature and pressure, which is safe and requires simple conditions. 2. The raw materials used in fermentation are usually starch, molasses or other agricultural and sideline products, and a small amount of organic and inorganic nitrogen sources can be added to react. Microorganisms can selectively use the nutrients they need, because there are different kinds. Based on this characteristic, wastewater and waste can be used as raw materials for fermentation to transform and renew biological resources. 3. The fermentation process is completed by biological automatic regulation, and the reaction is specific, so a single metabolite can be obtained. 4. Due to the biological reaction mechanism, some complex compounds can undergo highly selective chemical conversion reactions such as oxidation and reduction at specific sites, and more complex polymer compounds can also be produced. 5. It is very important to prevent and control the pollution of miscellaneous bacteria in the fermentation process. In addition to strict disinfection and air filtration, the reaction must be carried out under aseptic conditions. If mixed bacteria are polluted, the production will suffer huge economic losses, and if phage is infected, it will cause greater harm to fermentation. Therefore, maintaining aseptic conditions is the key to the success or failure of fermentation. 6. Microbial strains are the basic factors of fermentation. Through mutation and strain screening, high-yield excellent strains can be obtained, and products that are difficult to produce by conventional methods can be obtained by making full use of production equipment. 7. Compared with other industries, industrial fermentation has the advantages of less investment, quick effect and remarkable economic benefits. Based on the above characteristics, industrial fermentation has attracted more and more attention. Compared with traditional fermentation technology, modern fermentation engineering has more advantages than the above fermentation characteristics. In addition to using microorganisms, animal and plant cells and enzymes can also be used, and artificial "engineering bacteria" can also be used for reaction; The reaction equipment is not only a conventional fermentor, but a variety of bioreactors are used instead, with high degree of automation and continuity, which improves and innovates the fermentation level on the original basis.
