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 electrolysis cell with a microbial biocathode
Bioelectrochemistry, 2010 This study demonstrates, for the first time, the proof-of-principle of an MEC in which both the anodic and cathodic reaction are catalyzed by microorganisms. No expensive chemical catalysts, such as platinum, are needed. Two of these MECs were simultaneously operated and reached a maximum of 1.4 A/m(2) at an applied cell voltage of 0.5 V.

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.
