Enzymes, antibiotics, amino acids, and alcohols are all produced by fermentation in strictly controlled environments. Carbon dioxide (CO2) is the most important gaseous metabolic product in fermentation. As high CO2 levels are a potential health risk, CO2 level must be monitored in places, where there is a risk for elevated CO2 levels due to exhaust gas release to the surrounding environment. These type of places are wineries, breweries and other fermentation facilities.
