Charge accumulation and electron transfer kinetics in Geobacter sulfurreducens biofilms
(Royal Society of Chemistry, 2012-03)
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 ...
Open circuit potentiometry reports on internal redox states of cells in G. Sulfurreducens biofilms
(Pergamon-Elsevier Science Ltd, 2019-04-18)
The outstanding capacity of Geobacter sulfurreducens cells to directly connect their inner electron transport chain to a polarized electrode have prompted the application of a wide arrange of electrochemical techniques to ...
Stepping stones in the electron transport from cells to electrodes in Geobacter sulfurreducens biofilms
(Royal Society of Chemistry, 2013-04-30)
Geobacter sulfurreducens bacteria grow on biofilms and have the particular ability of using polarized electrodes as the final electron acceptor of their respiratory chain. In these biofilms, electrons are transported through ...
Structural and functional insights into the conductive pili of Geobacter sulfurreducens revealed in molecular dynamics simulations
(Royal Society of Chemistry, 2015-09-14)
Geobacter sulfurreducens (GS) electronically connects with extracellular electron acceptors using conductive protein filaments or pili. To gain insights into their role as biological nanowires, we investigated the structural ...
Biochemical capacitance of geobacter sulfurreducens biofilms
(Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, 2015)
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 ...
Physiological stratification in electricity-producing biofilms of Geobacter sulfurreducens
(Wiley VCH Verlag, 2014-02-02)
The 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. InGeobacter ...
