Forming microbial anodes under delayed polarisation modifies the electron transfer network and decreases the polarisation time required. [PDF]

, 2012
Microbial anodes were formed from compost leachate on carbon cloth electrodes. The biofilms formed at the surface of electrodes kept at open circuit contained microorganisms that switched their metabolism towards electrode respiration in response to a ...

Metabolic response of Geobacter sulfurreducens towards electron donor/acceptor variation [PDF]

Microbial Cell Factories, 2010
Geobacter sulfurreducens is capable of coupling the complete oxidation of organic compounds to iron reduction. The metabolic response of G. sulfurreducens towards variations in electron donors (acetate, hydrogen) and acceptors (Fe(III), fumarate) was investigated via (13)C-based metabolic flux analysis.

Detecting Excess Biofilm Thickness in Microbial Electrolysis Cells by Real‐Time In‐Situ Biofilm Monitoring

Biotechnology and Bioengineering, Volume 122, Issue 8, Page 2049-2062, August 2025.
ABSTRACT Long‐term stable operation of bioelectrochemical systems (BES) presupposes the avoidance of mass transfer limitations of the electroactive biofilm. Excessive pH‐gradients from bulk to electrode interface or substrate limitations of the electroactive biofilm are known to diminish the electrical performance of BES.

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Electron shuttle-mediated microbial Fe(III) reduction under alkaline conditions [PDF]

, 2018
Purpose: Extracellular Fe(III) reduction plays an important role in a variety of biogeochemical processes. Several mechanisms for microbial Fe(III) reduction in pH-neutral environments have been proposed, but pathways of microbial Fe(III) reduction ...

Charge accumulation and electron transfer kinetics in Geobacter sulfurreducens biofilms

Energy & Environmental Science, 2012
Electroactive bacteria can use a polarized electrode as final electron acceptor, allowing the use of electrochemical techniques for a very accurate quantification of its respiration rate. Biofilm cell respiration has been recently demonstrated to continue after the interruption of electrode polarization since these bacteria can store electrons in the ...
