Abstract
A fermention process is monitored by detecting ultrasound backscattered from the cells as a function of time. A transduceris placed in a fermentorand transmits ultrasound towards a reflecting surface. The transducer receives that portion of the ultrasound which reflects from the reflecting surface, as well as that portion of the ultrasound which backscatters from cellsbetween the transducerand the reflecting surface. Signals from the transducer are conditioned and subsequently processed to provide output to a controller regarding the status of the fermentation process in real time. The backscattering measurements can be used to determine a growth phase transition, such as the transition between the logarithmic growth phase of the cells and their stationary phase.
