Biofilm as a redox conductor: a systematic study of the moisture and temperature dependence of its electrical properties.
Some microbial biofilms are electrically conductive. However, the mechanism of electron transport remains unclear. Here, we show that μm-scale long-distance electron transport through electrode-grown Geobacter sulfurreducens biofilms occurs via redox conduction, as determined by electrical measurements performed under varied hydration states and temperatures.
