Dissolved Oxygen (DO) is the measure of the amount of oxygen that is distributed in a system. Measurements are generally taken in water using a DO probe and meter. When performing dissolved oxygen measurements in the laboratory or in the field, it should be considered which type of DO technology is most suitable to employ.
The measurement of dissolved oxygen is essential in fermentation and in cell culture to guarantee optimal conditions for the cell, since low levels of oxygen concentration can affect growth rate, nutrient absorption, cell morphology and synthesis of metabolism; that is equivalent to a decrease in the quality of the final product.
