The 3DFiberFilm project is developing three-dimensional textile carriers as innovative support structures for carboxydotrophic biofilms that enable CO₂, CO and H₂ to be converted into alcohols and organic acids. By combining textile technologies (DITF, Denkendorf) and bioprocess developments (IBVT, University of Stuttgart), the project is creating novel biofilm reactor systems with improved gas-liquid and liquid-cell mass transfer.
The three-dimensional textile carriers promote stable cell immobilization, high space-time yields and long-term operation – crucial prerequisites for industrial CO₂ utilization and a circular carbon economy.
In bubble column and jet recirculation reactors, experimental investigations are combined with data-based modeling to develop scalable strategies for increasing productivity with minimal energy input.
The project directly supports the objectives of the DFG priority initiative SPP 2494 “Productive Biofilms” by linking biofilm architecture, sustainable gas fermentation and innovations in the circular economy. In this way, it contributes to making industrial processes CO₂-negative.
