Electrochemical and Microbiological Characterization of Bioanode Communities Exhibiting Variable Levels of Startup Activity

Frontiers in Energy Research, 2019
Microbial electrochemical technologies (METs) require the establishment of anode biofilms to generate electrical current. The factors driving bioanode formation and their variability during startup remain unclear, leading to a lack of effective ...

The triheme cytochrome PpcF from Geobacter metallireducens exhibits distinct redox properties

FEBS Open Bio, 2018
Electrogenic bacteria, such as Geobacter, can couple the oxidation of carbon sources to the reduction of extracellular electron acceptors; such acceptors include toxic and radioactive metals, as well as electrode surfaces, making Geobacter a suitable ...

Geobacter Dominates the Inner Layers of a Stratified Biofilm on a Fluidized Anode During Brewery Wastewater Treatment

Frontiers in Microbiology, 2018
In this study, we designed a microbial electrochemical fluidized bed reactor (ME-FBR), with an electroconductive anodic bed made of activated carbon particles for treating a brewery wastewater.

Enhancement of methanogenesis by electric syntrophy with biogenic iron‐sulfide minerals

MicrobiologyOpen, 2019
Recent studies have shown that interspecies electron transfer between chemoheterotrophic bacteria and methanogenic archaea can be mediated by electric currents flowing through conductive iron oxides, a process termed electric syntrophy. In this study, we

Aromatic Amino Acids Required for Pili Conductivity and Long-Range Extracellular Electron Transport in Geobacter sulfurreducens

mBio, 2013
It has been proposed that Geobacter sulfurreducens requires conductive pili for long-range electron transport to Fe(III) oxides and for high-density current production in microbial fuel cells. In order to investigate this further, we constructed a strain

Electromicrobiology: Electron Transfer via Biowires in Nature and Practical Applications

BIO Web of Conferences, 2016
One of the most exciting developments in the field of electromicrobiology has been the discovery of electrically conductive pili (e-pili) in Geobacter species that transport electrons with a metallic-like mechanism.
