Unlimited foam formation and insufยฎcient foam collapse can have serious effects in an aerated system such as a fermentation process. Mechanical foam breakers are used in foam control to avoid the drawbacks associated with the use of chemical antifoams and defoaming agents. In this paper, two new foa
Akstract--We report experimental data of mass transfer of oxygen into yeast re-suspension and yeast culture in a batch pulsed baffled bioreactor and a stirred tank (ST) fermenter. Air bubbles are sparged into the bottom of both reactors and the kinetics of the liquid oxygen concentration followed us
The addition of light mineral oil was found to be effective in preventing foaming during plant cell cultivation in stirred tank fermenters without any adverse effect on cell growth. The optimum amount of oil is about 5% (by volume) of the total liquid medium. The best time for the addition is after
