Microalgae and cyanobacteria as biological agents of biocathodes in biofuel cells
BioTechnologia, 2021 Biofuel cells (BFCs) are an environmental friendly technology that can simultaneously perform wastewater treatment and generate electricity. Peculiarities that hinder the widespread introduction of this technology are the need to use artificial aeration ...

Bilirubin oxidase oriented on novel type three-dimensional biocathodes with reduced graphene aggregation for biocathode [PDF]
Biosensors and Bioelectronics, 2020 Aggregation of reduced graphene oxide (RGO) due to π-π stacking is a recurrent problem in graphene-based electrochemistry, decreasing the effective working area and therefore the performance of the RGO electrodes. Dispersing RGO on three-dimensional (3D) carbon paper electrodes is one strategy towards overcoming this challenge, with partial relief ...

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 ...

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.
