Detection of Fermentation Exhaust Gas in Parallel Bioreactors
During the operation of parallel bioreactors, the detection of fermentation exhaust gas is a crucial step. It is directly related to the monitoring and optimization of the fermentation process, as well as the quality and yield of the final product.
By monitoring the concentrations of CO₂ and O₂ in the exhaust gas, the metabolic status and activity of microorganisms can be understood, and the stability and efficiency of the fermentation process can be evaluated. CO₂ is the main chemical product in the alcohol fermentation process and the end product of cellular respiration and catabolism; while O₂ is crucial for the growth and metabolism of aerobic microorganisms.
Real-time monitoring of CO₂ and O₂ concentrations in the exhaust gas can obtain important respiratory metabolic parameters of the fermentation process, such as CO₂ evolution rate (CER), oxygen uptake rate (OUR), respiratory quotient (RQ), etc. These parameters provide operators with a basis for optimizing process parameters, thereby improving fermentation efficiency.
Specialized Fermentation Tail Gas Analyzer: Use specialized fermentation tail gas analyzers, such as the FG010 and FG021 series, etc. These instruments can monitor the concentrations of gases like CO₂, O₂, CH₄, and H₂S in the tail gas online. These instruments typically employ high-precision, fast-response sensors, such as CO₂ NDIR non-dispersive infrared analysis and O₂ zirconia oxygen sensors, to ensure the accuracy and real-time nature of the measurement results.
