Temperature, inocula and substrate: contrasting electroactive consortia, diversity and performance in microbial fuel cells [PDF]
The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and ...

Effect of surface roughness, biofilm coverage and biofilm structure on the electrochemical efficiency of microbial cathodes [PDF]
Biofilms of Geobacter sulfurreducens were formed under chronoamperometry at −0.5 V and −0.6 V vs. Ag/AgCl on stainless steel cathodes and tested for fumarate reduction.

The ‘porin-cytochrome’ model for microbe-to-mineral electron transfer [PDF]
Many species of bacteria can couple anaerobic growth to the respiratory reduction of insoluble minerals containing Fe(III) or Mn(III/IV). It has been suggested that in Shewanella species electrons cross the outer membrane to extracellular substrates via ‘

Microbial electrocatalysis with Geobacter sulfurreducens biofilm on stainless steel cathodes [PDF]
Stainless steel and graphite electrodes were individually addressed and polarized at−0.60V vs. Ag/AgCl in reactors filled with a growth medium that contained 25mM fumarate as the electron acceptor and no electron donor, in order to force the microbial ...

Effect of the semi-conductive properties of the passive layer on the current provided by stainless steel microbial cathodes [PDF]
Geobacter sulfur reducens biofilms were formed under constant polarisation at −0.6 V vs. Ag/AgCl on stainless steel cathodes to catalyse the reduction of fumarate.

Geobacter abundance in soil regulate by pH and iron-bearing minerals
As an electrogenic bacterium, Geobacter plays a crucial role in the geochemical cycles of arable soil. However, little is known about the existence of Geobacter and its impact factors in paddy soil and purple soil.

Electrobioremediation of oil spills [PDF]
Annually, thousands of oil spills occur across the globe. As a result, petroleum substances and petrochemical compounds are widespread contaminants causing concern due to their toxicity and recalcitrance.
