Denitrification in Microbial Fuel Cells Using Granular Activated Carbon as an Effective Biocathode
Energies, 2023 Nitrate (NO3−-N) and nitrites (NO2−-N) are common pollutants in various water bodies causing serious threats not only to aquatic, but also to animals and human beings.

Marine aerobic biofilm as biocathode catalyst [PDF]
Bioelectrochemistry, 2010 Stainless steel electrodes were immersed in open seawater and polarized for some days at -200 mV vs. Ag/AgCl. The current increase indicated the formation of biofilms that catalysed the electrochemical reduction of oxygen. These wild, electrochemically active (EA) biofilms were scraped, resuspended in seawater and used as the inoculum in closed 0.5L ...

Adapting a denitrifying biocathode for perchlorate reduction
Water Science and Technology, 2008 Perchlorate is widely used as a propellant in the aerospace and defense industries, and is of environmental concern due to its high mobility and inhibiting effect on thyroid function. An ideal treatment approach is bioreduction to chloride via dissimilatory perchlorate-reducing bacteria (PCRB).

Microbial Community Analysis of a Methane-Producing Biocathode in a Bioelectrochemical System [PDF]
Archaea, 2013 A methane-producing biocathode that converts CO2into methane was studied electrochemically and microbiologically. The biocathode produced methane at a maximum rate of 5.1 L CH4/m2projected cathode per day (1.6 A/m2) at −0.7 V versus NHE cathode potential and 3.0 L CH4/m2projected cathode per day (0.9 A/m2) at −0.6 V versus NHE cathode potential.
