The Biological CO2 Conversion project aim to optimising the biological acetic acid production under mesophilic conditions (37°C) from CO2 and H2 and advancing the field of Gas Fermentation Technologies.
The project for the Biological CO2 Conversion focuses on the bioconversion of industrial off-gases and specifically, CO2 into valuable biochemicals, particularly acetic acid, a key building block for biotechnological and chemical applications.
The aim is to optimize acetic acid production via microbial conversion of CO₂ and H₂ by acetogenic bacteria in mesophilic Trickle Bed Reactors at lab- and pilot-scale.
The key objectives include kinetic and microbial characterization of microbial communities involved in CO₂ fermentation and enhancement of process efficiency.
We will generate fundamental knowledge for improving acetic acid yield using mixed microbial cultures and for advancing Gas Fermentation Technology for sustainable chemical production.
This project is part of an EIC accelerator grant targeting CO2 valorisation for food and feed applications.
By bridging lab-scale experiments with scalable pilot systems, this project contributes to carbon utilization (CU), supporting the transition toward a circular bioeconomy.
