Electron transfer between microorganisms and an electrode—even across long distances—
enables the former to live by coupling to an electronic circuit. Such a system integrates …

Descriptions of the changeable, striking colors associated with secreted natural products
date back well over a century. These molecules can serve as extracellular electron shuttles …

Redox cycling of extracellular electron shuttles can enable the metabolic activity of
subpopulations within multicellular bacterial biofilms that lack direct access to electron …

Electricity generation by Geobacter sulfurreducens biofilms grown on electrodes involves
matrix-associated electron carriers, such as c-type cytochromes. Yet, the contribution of the …

Microbial extracellular electron transfer (EET) plays a crucial role in bioenergy production
and resource recovery from wastewater. Interdisciplinary efforts have been made to unveil …

Autotrophic microbes can acquire electrons from solid donors such as steel, other microbial
cells, or electrodes. Based on this feature, bioprocesses are being developed for the …

The electrically conductive pili of Geobacter species have been proposed to play an
important role in long-range electron transfer to Fe (III) oxides and other cells and have …

While early genetic and low-resolution structural observations suggested that extracellular
conductive filaments on metal-reducing organisms such as Geobacter were composed of …
