The Ability of the Raccoon Tail Water Plant (Ceratophyllum demersum) as a Biocathode in the Plant-Microbial Fuel Cell System

Jurnal Sumberdaya Alam dan Lingkungan
Plant-Microbial Fuel Cell (P-MFC) is a green technology because it uses a biocathode in the cathode compartment and also uses microorganisms to break down the chemical energy of organic matter into electrical energy.

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Microbial fuel cells with highly active aerobic biocathodes

Journal of Power Sources, 2016
AbstractMicrobial fuel cells (MFCs), which convert organic waste to electricity, could be used to make the wastewater infrastructure more energy efficient and sustainable. However, platinum and other non-platinum chemical catalysts used for the oxygen reduction reaction (ORR) at the cathode of MFCs are unsustainable due to their high cost and long-term

Draft Genome of Thermanaerothrix daxensis GNS-1, a Thermophilic Facultative Anaerobe from the Chloroflexi Class Anaerolineae [PDF]

, 2015
We present the draft genome of Thermanaerothrix daxensis GNS-1, a thermophilic member of the Chloroflexi phylum. This organism was initially characterized as a nonmotile, strictly anaerobic fermenter; however, genome analysis demonstrates that it encodes

Facilitating Electroactive Site Density Determination during Fuel‐Cell Testing

ChemElectroChem, Volume 12, Issue 10, May 24, 2025.
Testing the limits of quantifying the electroactive site density using Fourier‐transformed alternating current voltammetry in PGM‐free‐based PEMFCs. The increase in performance and durability the platinum group metal (PGM)‐free catalysts makes them a viable alternative to PGM catalysts at the cathodes of low‐temperature fuel cells.

Cathodic bacterial community structure applying the different co-substrates for reductive decolorization of Alizarin Yellow R [PDF]

Selective enrichment of cathodic bacterial community was investigated during reductive decolorization of AYR fedding with glucose or acetate as co-substrates in biocathode. A clear distinction of phylotype structures were observed between glucose-fed and

Biokinetics Of microbial consortia using biogenic sulfur as a novel electron donor for sustainable denitrification [PDF]

, 2018
In this study, the biokinetics of autotrophic denitrification with biogenic S0 (ADBIOS) for the treatment of nitrogen pollution in wastewaters were investigated. The used biogenic S0, a by-product of gas desulfurization, was an elemental microcrystalline
