Challenges and applications of nitrate-reducing microbial biocathodes

Bioelectrochemistry, 2023
Bioelectrochemical systems which employ microbes as electrode catalysts to convert chemical energy into electrical energy (or conversely), have emerged in recent years for water sanitation and energy recovery. Microbial biocathodes, and especially those reducing nitrate are gaining more and more attention.

Performance Analysis of Biocathode in Bioelectrochemical CO2 Reduction [PDF]

Catalysts, 2019
Microbial electrosynthesis (MES) biogas upgrading is done via reduction of carbon dioxide to methane through electroactive microbial catalysis. The baseline MES mode of operation showed about a 39% increase in the methane production rate compared to the open circuit mode of operation.

Improved Fe(II) regeneration from actual ferric sludge using a biocathode with granular sludge

Journal of Cleaner Production, 2023
Ferric sludge pollution and unsustainable utilization of Fe(II) reagent were tough nuts to crack for homogeneous Fenton treatment. Previous Fe(II) regeneration methods are still limited by high reagent consumption or low regeneration rate.
