Access through your institution Buy or subscribe To the Editor Certain microorganisms can use an electrode as a metabolic electron acceptor or donor by means of extracellular electron
transport (EET) processes1,2. Such microorganisms are studied as potential catalysts for electrode reactions such as the electrosynthesis of fuel precursors from reduction of CO2 using
renewable sources of electricity3. The appeal of microbial electrode catalysts is that they self-assemble and self-heal, and the prospect of optimizing their catalytic properties (for
example, reaction product and yield) through molecular engineering. In addition to enabling electron transport across a microbial/electrode interface, EET processes can often facilitate
long-distance electron transport, resulting in the formation of multi-cell-thick electrode-grown biofilms, which are electrically conductive and can exceed 100 μm thickness. Such biofilms
challenge the notion that biological electron transport is limited to molecular length scales. The fundamental mechanism of EET underlying biofilm conductivity has implications across many
disciplines and is yet unresolved. This is a preview of subscription content, access via your institution RELEVANT ARTICLES Open Access articles citing this article. * LONG-DISTANCE ELECTRON
