Kinetic characterization and modeling of CO2-CO fermentation for acetic acid production

Characterization of mass transfer kinetics of gases in CO2/CO fermentation, determining microbial kinetics, and modeling biological CO2/CO conversion to acetic acid across various reactor types.

The project aims to enhance the understanding of CO2 and CO fermentation for acetic acid production by characterizing gas-liquid mass transfer kinetics, microbial kinetics, and process modeling across various reactor configurations.

 

The study will investigate the intricate relationship between mass transfer rate and microbial growth rate to optimize the conditions for determination of microbial growth kinetics.

 

Additionally, microbial kinetic determination will focus on key microbial groups, analyzing growth rates, substrate utilization, and product formation under varying conditions.

 

Modeling will integrate mass transfer, microbial kinetics and thermodynamics to simulate CO2 and CO conversion pathways, evaluating its performance across different reactor configurations.

 

The project will provide insights into the fundamental constraints of biological CO2/CO conversion and support the development of scalable and efficient bioprocesses.

 

By combining experimental data with predictive models, this research will contribute to optimizing bioreactor design and advancing biorefinery conversion strategies for sustainable biochemical production.
