The production level of microbial fermentation mainly depends on the genetic characteristics of the strain itself and the culture conditions. The application scope of fermentation engineering includes pharmaceutical industry, food industry, energy industry, chemical industry, agriculture and other fields. In the process of microbial fermentation cultivation, it is necessary to proportion the required influencing components.
