Bacteria with CO2 on the Menu

Researchers at TU Graz and ACIB feed bacteria with CO2 and other gases in a gas fermentation process. What humans store as fat, these bacteria deposit as bioplastics. The research team: Markus Reichartinger, Regina Kratzer, Carina Frank and Vera Lambauer.

As well as little ants in shades of blue. All these illustrative materials are made from a special bioplastic that researchers at TU Graz are working on. Bacteria are fed with a mixture of H₂, O₂ and CO₂ and produce a biopolymer as a metabolic product.
