There are many dynamic methods for measuring the volumetric mass transfer coefficient. The "gas out-gas in" method can directly determine the volumetric m a s s transfer coefficient in a bioreactor system and provide estimates of the volumetric microbial oxygen uptake rate and the average oxygen sat
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.
