Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions

Expressing the Geobacter metallireducens PilA in Geobacter sulfurreducens Yields Pili with Exceptional Conductivity

mBio, 2017
The electrically conductive pili (e-pili) of Geobacter sulfurreducens serve as a model for a novel strategy for long-range extracellular electron transfer. e-pili are also a new class of bioelectronic materials.

From microbial fuel cell (MFC) to microbial electrochemical snorkel (MES): maximizing chemical oxygen demand (COD) removal from wastewater [PDF]

, 2011
The paper introduces the concept of the microbial electrochemical snorkel (MES), a simplified design of a “short-circuited” microbial fuel cell (MFC). The MES cannot provide current but it is optimized for wastewater treatment.

A periplasmic and extracellular c-type cytochrome of Geobacter sulfurreducens acts as a ferric iron reductase and as an electron carrier to other acceptors or to partner bacteria [PDF]

, 1998
An extracellular electron carrier excreted into the growth medium by cells of Geobacter sulfurreducens was identified as a c-type cytochrome. The cytochrome was found to be distributed in about equal amounts in the membrane fraction, the periplasmic ...

Azurins With Tunable Reduction Potentials as Redox Mediators for Extracellular Electron Transfer

ChemBioChem, Volume 27, Issue 14, 29 July 2026.
Electroactive microbe Shewanella oneidensis reduced non‐native electron transfer protein, azurin, via extracellular electron transfer (EET) with dependence on azurin redox potential. Utilizing azurin in EET‐driven bio‐(electro)catalysis improved fuel cell current and accelerated textile dye decolorization.
