Electroactive bacteria can use a polarized electrode as final electron acceptor, allowing the of electrochemical techniques for very accurate quantification its respiration rate. Biofilm cell has been recently demonstrated to continue after interruption polarization since these store electrons in haem groups exocytoplasmic cytochromes. Interestingly, it shown that when is connected again, stored be recovered current superimposed basal steady state produced by biofilm respiration. This work...

Abstract 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 maximum can produce because fundamental properties mechanism of extracellular electron transport and factors limiting cell respiration remain unclear. In this work, a strategy for investigation biofilms is presented. Numerical modeling response G. cultured on rotating disk electrode has...
Geobacter sulfurreducens bacteria grow on biofilms and have the particular ability of using polarized electrodes as final electron acceptor their respiratory chain. In these biofilms, electrons are transported through distances more than 50 μm before reaching electrode. The way in which across biofilm matrix such large remains under intense discussion. None two mechanisms proposed for explaining process, hopping outer membrane cytochromes metallic like conduction conductive PilA filaments,...

Biochar electrodes can attain current densities similar to graphite while being more cost-effective and environmentally friendly.
Bakterien unter Strom: Konfokale Raman-Mikroskopie und eine 3D-Strukturanalyse wurden genutzt, um Redoxgradienten in Strom produzierenden Biofilmen vivo zu untersuchen. Der Ansatz liefert wichtige neue Informationen über den Mechanismus der Elektronenleitung diesen Systemen.
Abstract An electrical model able to decouple the electron pathway from microbial cell machinery impedance terms is introduced. In this context, capacitance characteristics of biofilm are clearly resolved. other words, allows separating, according advantage frequency and spectroscopic response approach, different controlling performance respiratory process thus directly related electricity production process. The can be accurately fitted voltammetry measurements obtained under steady‐state...
Galvanic coupling with a biocompatible conductive material can make accesible unexplored electron sources for bacteria.
In the lack of organic carbon sources, with an electrode as electron donor aerobic denitrification yields higher current production and faster nitrate removal than anaerobic denitrification.
