RedOx Sensors
The RedOx potential (Reduction / Oxidation) of a bioreactor culture can be measured using a RedOx sensor. The value of the reading of the sensor can depend on pH, growth phase, growth medium components, and fermentation end-products (especially fermentation acids and hydrogen). RedOx measurement is also used in anaerobic fermentations as an alternative to the Dissolved Oxygen sensor which does not give much process information in anaerobic situations. The RedOx value can be measured but cannot be directly controlled.
