The volumetric oxygen transfer coefficient, KLa, is one of the most important parameters in the scaleup of aerobic fermentation processes. It is a measure of the gas-liquidoxygen transfer performance of a given fermentor. Because of the involvement of oxygen in the metabolic energy supply, the KLa v
The solubility of oxygen in the liquid phase of a bioreactor was changed by a ramp change of temperature, and k,a was determined from the resulting return to equilibrium of dissolved oxygen activity. The maximum k,a that can be measured by this method in a standard laboratory scale bioreactor is 14.
