Abstract : The patent describes a method of controlling foam generated by the biological reaction of a fluid culture medium in a container. The inlet of a pump is connected to withdraw foam from the head space above the culture medium and to withdraw culture medium from the container. The pump intimately mixes the withdrawn foam and the withdrawn medium. This compressed mixture of withdrawn foam and withdrawn culture medium is then reintroduced into the culture medium in the container thereby resulting in the intimate dispersion of the air, the microbial mass and the culture medium within the container.
