Electron transport by living cable bacteria


Cable bacteria are centimeter-long, multicellular filamentous bacteria, which are globally occurring in marine and freshwater sediments.

In their current study an international team of scientists - among them Michael Wagner, Department of Microbiology and Ecosystem Science - presents measurements on individual cable-bacteria filaments that allow them to quantify a voltage drop along cable-bacteria filaments and show a transport of electrons over several millimeters. This is orders of magnitude longer than previously known for biological electron transport.

Long-distance electron transport in individual, living cable bacteria: Jesper T. Bjerga, Henricus T. S. Boschker, Steffen Larsen, David Berry, Markus Schmid, Diego Millo, Paula Tataru, Filip J. R. Meysmand, Michael Wagner, Lars Peter Nielsen, and Andreas Schramm
