Why foaming is undesirable is as it reduces the productive volume, increases cost, and threat the sterility of a fermenter. Defoaming agent The inherent characteristic of a de-foaming agent is that it is surface-active but highly insoluble in water, with an extremely high surface area it is dispersed as tiny droplets in the form of an . endobj endobj It has low water solubility, and better foam suppression ability than defoaming ability, thus, please add this defoamer to the oxidation-fermentation basal medium to suppress foam during the whole fermentation. Aeration testing is based on sparging air in the foaming medium allowing partial reproduction of the gas-liquid hydrodynamic encountered in bioreactors.
