Antifoams are chemical agents which, as the name would suggest, are designed to control the formation of foam. The SlideShare family just got bigger. Transfer of oxygen from a gas phase to a liquid phase is complicated by presence of cells, product formation, ionic species, and antifoaming agents. The generation of foam during fermentation processes is caused by the existence of foam-active substances in the fermentation broth, escaping gas/air and turbulences within the fermenter. Silicone-based antifoam agents are the most common chemicals used to manage foam but product contamination is a major consideration. Silicone free, Accepta 2904 will not create filtration or oxygen transfer problems that can lead to reduced growth rates. Antifoam (defoamer) chemicals are a crucial part of many commercial fermentation processes. It reduces antifoam agents while the reduction in yeast invigorates .
