Summary The concentration of ammonium in the medium of anEscherichia coli fermentation during ammonium limitation was followed by means of a newly developed semiconductor device, the ammonia gas-sensitive thin platinum metal oxide semiconductor structure (Pt-TMOS). It has been shown that the ammonia sensitivity of the sensor was sufficient for determination of ammonium concentrations at growth limitation due to ammonium depletion. Furthermore, the corresponding ATP concentration and dissolved oxygen tension during the progress of the fermentation was followed.
