Microbes can impressively transfer electrons over long distances, yet our knowledge about them remains limited

PhD defence, Friday 9 February 2024, Bo Wang

Bo Wang

During his/her PhD studies, Bo Wang investigated microbial electron transfer in electroactive microorganisms, delving into both applications and fundamentals. Extracellular electron transfer in electroactive microorganisms facilitates microbial communication with the external environment, electron release, and energy recharge. Bo Wang investigated electromethanogenesis, an application leveraging electroactive microorganisms for enhanced electron transfer rates and the production of valuable chemicals and fuels, e.g., CH4. While external power is currently required, he explored the potential of green driving-power using natural solar light that was constrained by inherent day/night intermittence. Additionally, Bo Wang delved into the mysteries of long-distance electron transfer mechanism in multicellular filamentous cable bacteria, investigating their conductor compositions and conduction mechanisms using multiple molecular toolboxes.
His research findings contribute to the understanding of extracellular electron transfer in electroactive microorganisms from applications and fundamental directions, which can advance the development of carbon-neutral technologies and broaden applications in the field of electromicrobiology.

The PhD study was completed at Department of Biology, and Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.
