ON DISSOLVED CARBON DIOXIDE IN PENICILLIN FERMENTATIONS

Abstract
The behavior of dissolved carbon dioxide in penicillin fermentations was studied. It is demonstrated that the partial pressure of carbon dioxide in the offgas and of that dissolved in the fermentation medium were not in equilibrium. Excessive dissolution of carbon dioxide occurs during the course of the fermentation and can be attributed to the slower rate of CO2 desorption from the fermentation medium compared to the rate of CO2, absorption from the cell respiration.
