The relay network of Geobacter biofilms
(Royal Society of Chemistry, 2016-07-27)
While actual models explaining electron conduction in electricity producing biofilms have evolved separately to apparent irreconcilable conceptual positions, finding cytochrome complexes in the external matrix of Geobacter ...
A long way to the electrode: how do Geobacter cells transport their electrons?
(Portland Press, 2012-12-01)
The mechanism of electron transport in Geobacter sulfurreducensbiofilms is a topic under intense study and debate. Although some proteins were found to be essential for current production, the specific role that each one ...
Proving Geobacter biofilm connectivity with confocal Raman microscopy
(Elsevier Science Sa, 2016-11-04)
We report here an . in-vivo, non-invasive, depth profiling study on an electrically-active biofilm by Confocal Raman Microscopy. Films based on . Geobacter sulfurreducens bacteria were grown onto an indium tin oxide (ITO) ...
Opportunities behind the unusual ability of Geobacter sulfurreducens for exocellular respiration and electricity production
(Royal Society Of Chemistry, 2011-05-11)
The possibility to improve the connection of cells to the electrode is significant for microbial fuel cell technology. In this communication we demonstrate that an improved connection can be made by controlling the ...
Limitations for current production in Geobacter sulfurreducens biofilms
(Wiley Vch Verlag, 2013-02-18)
Devices that exploit electricity produced by electroactive bacteria such as Geobacter sulfurreducens have not yet been demonstrated beyond the laboratory scale. The current densities are far from the maximum that the ...
Biochemical capacitance of geobacter sulfurreducens biofilms
(Wiley, 2015-07-16)
An electrical model able to decouple the electron pathway from microbial cell machinery impedance terms is introduced. In this context, capacitance characteristics of the biofilm are clearly resolved. In other words, the ...
Electrochemical insight into the mechanism of electron transport in biofilms of Geobacter sulfurreducens
(Elsevier, 2011-07-08)
Electroactive bacterial biofilms can be produced on a polarized electrode by forcing its use as the final electron acceptor for bacterial respiration. This strategy offers the researcher the unique possibility to control ...
Analysis of nifH-RNA reveals phylotypes related to Geobacter and Cyanobacteria as important functional components of the N2-fixing community depending on depth and agricultural use of soil
(Blackwell Publishing, 2017-05)
In this survey, a total of 80 787 reads and 28 171 unique NifH protein sequences were retrieved from soil RNA. This dataset extends our knowledge about the structure and diversity of the functional diazotrophic communities ...

Crystallographic orientation and electrode nature are key factors for electric current generation by Geobacter sulfurreducens
(Elsevier, 2014-02-25)
We have investigated the influence of electrode material and crystallographic structure on electron transfer and biofilm formation of Geobacter sulfurreducens. Single-crystal gold—Au(110), Au(111), Au(210)—and platinum—Pt(100), ...
