## Abstract The determination of the overall volumetric massβtransfer coefficient with the dynamic measurement technique involves modeling, parameter estimation, and experimental design. The combination and extension of previous efforts lead to some suggestions for improvements.
The oxygen transfer rate (OTR) is the most suitable measurable parameter to quantify the physiological state of a culture of aerobic microorganisms since most metabolic activities depend on oxygen consumption. Online measurement of the oxygen transfer rate in stirred bioreactors is state of the art
