✦ Synopsis

A rapid and internally consistent technique has been developed to measure the volumetric oxygen transfer coefficient, k ~a , i n fermentation systems. The method consists of tracing the dissolved 0 2 concentration of the fermentation broth during a short interruption of the aeration. The O2 concentration trace thus obtained can be analyzed to determine the values of k ~a . Additional experiments on prolonged 0 2 starvation, carried out to find the limitation of the technique, suggest that 0 2 uptake rate will vary if a prolonged 12-10 min.) 0 2 starvation occurs.

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

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
