Cable bacteria conduct protons over 100 micrometers, hinting at bioelectronic potential

Jan 20, 2025

U.S. Naval Research Laboratory and Aarhus University, Denmark, researchers have confirmed protonic conductivity over distances exceeding 100 micrometers along filamentous Desulfobulbaceae, commonly referred to as cable bacteria. Findings provide insights into microbial proton transport mechanisms and open pathways for applications in bioelectronics.
