Exploring biofilm formation by the bacterium Sporomusa ovata for microbial electrosynthesis – converting electric energy and CO2 to organic carbon molecules

PhD defence, Thursday, 27th March 2025, Louise Vinther Grøn

Louise Vinther Grøn

During her PhD studies, Louise Vinther Grøn explored cell attachment and biofilm formation by the bacterium Sporomusa ovata. This microbe is capable to convert CO2 with H2 into organic molecules, such as acetate, and is thus an intriguing biocatalyst for novel CO2 conversion technologies, one of them being microbial electrosynthesis.

Her research explored how biofilm formation by this bacterium can be increased and investigated the importance of biofilm formation on the electrode for microbial electrosynthesis. This interdisciplinary work provides insights into the biofilm formation capabilities of this unique microbe, which is of value for the further development of microbial electrosynthesis, as a relevant biological CO2 conversion technology.

The PhD study was completed Department of Biological and Chemical Engineering, Faculty of Technical Sciences, Aarhus University.
