Electrons can be exchanged extracellularly through the outer envelope of single-celled microorganisms or internally in multicellular bacteria and thereby improve resource extraction and interaction with other organisms and the surrounding environment. Current research in electromicrobiology is rapidly expanding the known diversity of microbes, molecules, mechanisms, metabolisms, and biogeochemical processes engaged in extracellular electron exchange.

How far have we come? What is the importance? And how can we leverage this knowledge to meet our greatest challenges in areas such as the environment, energy, climate, agriculture, or medicine?

In 2025, the Center for Electromicrobiology at Aarhus University, Denmark will host the 4th Electromicrobiology Conference, bringing together 110 researchers from diverse fields, career stages, and geographies. These biennial conferences aim to capture the latest developments and questions in electromicrobiology all the way from molecular mechanisms and microbial interactions to natural ecosystems and technological applications.

Join us as we explore these exciting frontiers and their potential to transform our world.
