Electrodeposited Hybrid Biocathode-Based CO₂ Reduction via Microbial Electro-Catalysis to Biofuels

Membranes, 2021
Microbial electrosynthesis is a new approach to converting C1 carbon (CO2) to more complex carbon-based products. In the present study, CO2, a potential greenhouse gas, was used as a sole carbon source and reduced to value-added chemicals (acetate ...

Enhanced microbial electrosynthesis by using defined co-cultures [PDF]

The ISME Journal, 2016
Abstract Microbial uptake of free cathodic electrons presents a poorly understood aspect of microbial physiology. Uptake of cathodic electrons is particularly important in microbial electrosynthesis of sustainable fuel and chemical precursors using only CO2 and electricity as carbon, electron and energy source.

Electroactive Microbiomes: Electron Transfer Mechanisms and Environmental Biotechnology Applications

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Electroactive microbiomes couple direct, mediated, conductive, and interspecies electron transfer with biofilm organisation to drive wastewater treatment, bioremediation, resource recovery, carbon conversion, and biosensing. Their performance depends on balancing electron transfer, mass transport, community structure, and electrode–biofilm interactions
