Studies on the Ventilation in Submerged Fermentations

Abstract

By using the modified Severinghaus CO2 electrode, the relationship between partial pressure of carbon dioxide in effluent gas and that in culturing system was investigated. Partial pressure of carbon dioxide in gas phase was almost equivalent to the average value of dissolved carbon dioxide tension in liquid phase for a given short time of the fermentation. The term of re was introduced in order to study the dynamic characteristics of carbon dioxide evolution in submerged fermentors. The dynamic characteristics of respiration in submerged fermentation was also studied by using biological rab and re.
