Notes:
A method by which a paramagnetic oxygen analyzer is used to determine oxygen consumption and carbon dioxide production during aerobic fermentation of Torulopsis utilis is described. The volume of carbon dioxide produced is not necessarily related to the volume of oxygen consumed by the microorganisms. For this reason, all carbon dioxide is removed from the effluent gas before it enters the analyzer when determining oxygen consumption. A method for calibrating the analyzer to correct for this removal is outlined. When determining carbon dioxide, effluent gas bypasses the carbon dioxide absorption tower before entering the analyzer. The carbon dioxide which it contains dilutes the oxygen remaining in the gas. The magnitude of this dilution can be used to calculate the percentage of carbon dioxide produced in terms of the air flow to the fermentor. Equipment required to alternately measure and record oxygen consumption and carbon dioxide production is described.
