A measuring and control quadrupole mass spectrometer system (QMS) has been installed to monitor fermentation processes on industrial scale. This system enables us to carry out on-line monitoring of dissolved gases and volatile compounds such as O//2, CO//2, N//2, propanol being present in the fermentation broth and the same components in exit gases of the fermentors. In addition the QMS system can make the exact determination of the compounds made volatile through some chemical reactions, too (i. e. NH//3, pyruvic acid, 2-ketoglutaric acid, phenilacetic acid, CO//3**2** minus ). Present work is focussed on the measurement of CO//2 produced in the fermentation process, the dependence of CO//2 dissolved physically on the carbonate content and pH of the broth.
