<p>PURPOSE: To accurately control the state of the fermentation by measuring infrared absorption, etc., of the fermentation broth at a specific infrared absorption frequency of a component whose concentration changes in the course of the fermentation by microorganism. CONSTITUTION: Infrared absorption or a change of infrared absorption of a fermentation broth at a specific infrared absorption frequency of a component (a sugar, an alcohol, etc.), whose concentration changes in the course of the fermentation by microorganism, is measured. Infrared attenuated total reflection spectroscopy (IR-ATR) enables the easy separation of absorption of water from that of the material to be measured and the amount of the material is qualitatively measured without receiving the influence of water.</p> |
