Transcriptional response to elemental sulfur in Geobacter sulfurreducens

Bioscience, Biotechnology, and Biochemistry
Abstract The metal-reducing bacterium Geobacter sulfurreducens PCA is capable of anaerobic respiration using elemental sulfur as an electron acceptor. Despite 3 decades since its isolation, the molecular mechanisms underlying sulfur respiration remain unclear. In this study, we conducted a transcriptome analysis of G.

Anode biofilm transcriptomics reveals outer surface components essential for high density current production in Geobacter sulfurreducens fuel cells.

PLoS ONE, 2009
The mechanisms by which Geobacter sulfurreducens transfers electrons through relatively thick (>50 microm) biofilms to electrodes acting as a sole electron acceptor were investigated. Biofilms of Geobacter sulfurreducens were grown either in flow-through

Supercapacitors Based on c‐ Type Cytochromes Using Conductive Nanostructured Networks of Living Bacteria [PDF]

, 2012
Supercapacitors have attracted interest in energy storage because they have the potential to complement or replace batteries. Here, we report that c ‐type cytochromes, naturally immersed in a living, electrically conductive microbial biofilm, greatly ...

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.

Forming electrochemically active biofilms from garden compost under chronoamperometry [PDF]

, 2008
Dimensionally stable anodes (DSA) were polarized at different constant potential values for several days in garden compost. After an initial lag period ranging from 1 to 10.5 days, the current increased fast and then stabilized for days.

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.
