An electroactive artificial biofilm has been optimized for the cathodic reduction of fumarate
by Shewanella oneidensis. The system is based on the self-assembly of multi-walled carbon …

In the recent years, considerable body of research has been carried out in the field of
bioelectrochemical systems (BESs) for treatment of wastewater and generation of power. In …

There have been many factors observed that affect electron transfer processes between the
cells in biofilms and a solid electrode. In this work we investigated the role of pH, redox …

Microbial respiration is based on electron transfer from electron donors to electron acceptors–
a series of reactions facilitated by a cascade of energetic substances; these are well-known …

Electrochemical gradients are the backbone of basic cellular functions, including chemo-
osmotic transport and ATP synthesis. Microbial growth, terminal respiratory proteins and …

The electrochemist will tell you that cyclic voltammetry (CV) is absolutely necessary to
diagnose an electrochemical reaction occurring in an electrochemical cell. By merely …

The accumulation of protons in electro-active biofilms (EABfs) has been reported as a critical
parameter determining produced currents at the anode since the very beginning of the …

The role of the electroactive surface area (EASA) and of the non-electroactive surface area
(nEASA) was studied to better understand electroactive biofilm's (EAB) growth and …

This review examines the electrochemical techniques used to study extracellular electron
transfer in the electrochemically active biofilms that are used in microbial fuel cells and other …

Confocal Resonance Raman Microscopy (CRRM) was used to probe variations of redox
state of c-type cytochromes embedded in living mixed-culture electroactive biofilms exposed …
