Microbial electrosynthesis

Microbial Electrosynthesis is the process in which bacteria convert CO2 into biofuels or other biochemicals by the use of electric energy delivered by an electrode. Microbial electrosynthesis is of high interest for the reduction of CO2 emissions, as well as for the conversion of excess electrical energy into a storable form. The main goal of the Microbial Electrosynthesis Research Group is to investigate acetogenic bacteria capable of microbial electrosynthesis and to unravel their extracellular electron transfer and biofilm formation mechanisms.


Biocorrosion

Bacteria capable of consuming extracellular electrons are not only interesting for new applications (such as microbial electrosynthesis), but can also cause severe material degradation. Biocorrosion is the process in which microorganisms cause the corrosion of steel or other materials; leading to huge economic losses. The Microbial Electrosynthesis Research Group aims at investigating the extracellular electron transfer mechanisms of biocorroding bacteria.


Biofilm formation

Very little is known about biofilm formation by acetogenic bacteria, even though biofilms could be very useful for the development of new biotechnological applications, such as microbial electrosynthesis and gas fermentation. The Microbial Electrosynthesis Research Group has as goal to unravel and improve biofilm formation by acetogenic bacteria.


Gas fermentation

Biofilm formation by acetogenic bacteria could be beneficial for the gas fermentation of CO2 and H2 into biofuels and biochemicals. The Microbial Electrosynthesis Research Group wants to evaluate and improve biofilm formation by acetogenic bacteria in biofilm-based gas fermentors.
