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

Mixed Ionic and Electronic Charge Transport in Conductive Protein Fibers Revealed with DC Electrical Measurements

Advanced Materials, Volume 37, Issue 47, November 27, 2025.
M13 bacteriophage films deposited on micro interdigitated electrodes behave as a Randles simplified equivalent circuit under direct current. We derive contact and film resistance as well as capacitance of films of M13 phages, aromatic curli fibers or pilA‐containing nanowires.

Physiological Stratification in Electricity‐Producing Biofilms of Geobacter sulfurreducens

ChemSusChem, 2013
AbstractThe elucidation of mechanisms and limitations in electrode respiration by electroactive biofilms is significant for the development of rapidly emerging clean energy production and wastewater treatment technologies. In Geobacter sulfurreducens biofilms, the controlling steps in current production are thought to be the metabolic activity of cells,

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.

Computational and Experimental Analysis of Redundancy in the Central Metabolism of Geobacter sulfurreducens

PLoS Computational Biology, 2005
Previous model-based analysis of the metabolic network of Geobacter sulfurreducens suggested the existence of several redundant pathways. Here, we identified eight sets of redundant pathways that included redundancy for the assimilation of acetate, and for the conversion of pyruvate into acetyl-CoA.
