FIELD: biotechnologies.
SUBSTANCE: method is proposed to produce a foaming agent. The method includes cultivation of a microorganism in a fermentative medium, the cells of which produce a foaming agent extracellularly. At the same time the fermentative medium contains a defoaming agent, which has opacity temperature. Then the defoaming agent is removed at the temperature of the fermentative medium of at least 10°C higher than the opacity temperature of the defoaming agent.
EFFECT: method makes it possible to simplify removal of a defoaming agent from a fermentative medium.
