Commonly used antifoaming agents are certain alcohols (cetostearyl alcohol), insoluble oils (castor oil), stearates, polydimethylsiloxanes, and other silicone derivatives, ether, and glycols. 22 0 obj <>stream On the contrary, an antifoaming agent is an additive which reduces the surface tension of a solution or emulsion, thus inhibiting or modifying the formation of a foam. Antifoams can also control foam during the downstream separation of fermentation products from fermentation broth. Why foaming is undesirable is as it reduces the productive volume, increases cost, and threat the sterility of a fermenter.
