Background

During the fermentation of microorganisms, a large amount of air bubbles are often generated in the fermenter due to the agitation, vibration of the machine and interaction inside the liquid. In the actual fermentation process, manufacturers need to reduce the loading amount in order to contain the foam to prevent overflow, thereby affecting the productivity. Meanwhile, once the foam overflows, the raw material is lost due to the bubbles, which causes waste. In addition, if the foam is stable and unbroken for a long time, the breathing of flora is influenced, which not only causes incomplete fermentation of bacteria, but also leads to production of other substances except the target product and possible deterioration of the material. In general, the fermentation process requires foam control. The traditional defoaming method comprises physical defoaming and chemical defoaming, wherein the physical defoaming is most commonly mechanical defoaming, the mechanical defoaming has certain limitation and can only eliminate the near foam of the stirring paddle, and the chemical defoaming agent is added with a defoaming agent or defoaming powder, so that the fermentation cost is increased, the auxiliary agent is added into the fermentation liquor, and the purity of the fermentation liquor cannot be ensured.
