Reaction engineering analysis of gas fermentation with Clostridium aceticum

Alexander Mayer, doctoral thesis Technical University of Munich, 2018

Clostridium aceticum converts syngas to acetate. Reaction engineering analysis performed in fully controlled stirred-tank bioreactors revealed a strong carbon monoxide (CO) inhibition and elucidated important physiological characteristics of this acetogenic microorganism converting syngas components. Despite the strong CO inhibition kinetics, syngas conversion with increased CO concentrations was enabled by adequate process control in a continuously operated membrane bioreactor.
