Research projects
The “BioEnergy & Environment” team focus its interests on the bio-activation of small molecules by metalloenzymes and anaerobic micro-organisms. The themes are centred around the study of the energy metabolism of microorganisms capable of metabolising diverse gasses such as CO, CO2, CH4 and H2. The model microorganisms will be the two photosynthetic bacteria Rhobobacter capsultatus and Rhodospirillum rubrum and the methanogenic archae Methanococcus maripaludis. Understanding the enzymatic mechanisms involved in these processes as well as the optimisation of catalytic processes for applications in sustainable chemistry are at the heart of the team's concerns.

Optimization of biological water-gas shift reaction, a key reaction in the synthesis of green fuels
