Oxygen biocathode based on laccase Pleurotus ostreatus HK-35 for biofuel cell [PDF]

Электрохимическая энергетика
The main reasons that make mankind look for new sources of energy are decreasing dependence on fossil fuels and reducing pollution. Wastewater treatment with the help of microbial fuel cells is an area where these two goals can be combined.

Cu and SnO2‐Modified Carbon Felt for Electroenzymatic CO2 Upcycling

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
Bioelectrode platform for sustainable CO2‐to‐formate conversion, combining electrochemical cofactor regeneration with enzyme immobilization. Cu‐modified electrodes enhanced NADH recycling compared to SnO2, while coupling with affinity‐immobilized formate dehydrogenase improved enzymatic turnover and stability while maintaining faradaic efficiency.

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Metatranscriptomics Supports the Mechanism for Biocathode Electroautotrophy by “Candidatus Tenderia electrophaga”

mSystems, 2017
Biocathodes provide a stable electron source to drive reduction reactions in electrotrophic microbial electrochemical systems. Electroautotrophic biocathode communities may be more robust than monocultures in environmentally relevant settings, but some ...

Oxygen Transport in Composite Biocathodes

ECS Proceedings Volumes, 2002
A recent advance in the engineering of biological oxygen cathodes has resulted in a laccase cathode that, when mounted on a rotating disk, operates at a current density controlled by transport of oxygen to the disk surface. Indeed, electrodes have been demonstrated that generate current densities near 5 mA/cm at 1000 rpm, greatly exceeding the current ...

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.

Mitigating VFA accumulation in hydrogen‐assisted anaerobic digestion through MEC integration

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 4, Page 915-924, April 2026.
Abstract BACKGROUND Biological hydrogenotrophic methanization is a promising method to improve biogas quality in anaerobic digestion systems. However, hydrogen‐assisted anaerobic digesters (AD‐H2) are prone to volatile fatty acid (VFA) accumulation and process instability.

A Facultative Electroactive Chromium(VI)-Reducing Bacterium Aerobically Isolated From a Biocathode Microbial Fuel Cell

Frontiers in Microbiology, 2018
A facultative electroactive bacterium, designated strain H, was aerobically isolated from the biocathode of a hexavalent chromium (Cr(VI))-reducing microbial fuel cell (MFC). Strain H is Gram-positive and rod shaped (1–3 μm length).

Identifying local gradients in methane-producing biocathodes

Trends in Biotechnology
CH4-producing bioelectrochemical systems (BES) are a promising alternative to convert CO2 and electricity into CH4. However, not much is known about the local conditions and possible gradients at CH4-producing biocathodes, especially when using granular activated carbon (GAC) as the electrode material. Detecting local conditions at different depths and
