Background technique

Microbial fermentation refers to the process of using microorganisms to convert raw materials into products required by humans through specific metabolic pathways under suitable conditions. The level of microbial fermentation production mainly depends on the genetic characteristics and culture conditions of the strain itself. The microbial fermentation process is divided into aerobic fermentation and anaerobic fermentation according to the fermentation conditions. Aerobic fermentation methods include liquid surface culture fermentation, fermentation on the surface of porous or granular solid medium, and aerobic submerged fermentation. Anaerobic fermentation adopts submerged fermentation without oxygen. Therefore, both aerobic and anaerobic fermentation can be achieved by deep culture, and this culture is completed in a cylindrical fermenter with a certain ratio of diameter to height.

In the process of microbial fermentation, the fermentation reaction speed is often increased by adding a stirring device, so that the fermentation period is shortened, while most of the traditional stirring devices are installed on the stirring rod with different shapes and angles.
