Background

Microbial fermentation refers to a process of converting into a desired product through specific metabolism using a microorganism as a raw material under a suitable environment, and the microbial fermentation may be batch fermentation or continuous fermentation. In the continuous fermentation process, new culture solution is added into the fermentation tank at a certain speed, and meanwhile, old culture solution in the fermentation tank flows out at the same speed so as to maintain the liquid amount in the fermentation tank stable.
