Azurins With Tunable Reduction Potentials as Redox Mediators for Extracellular Electron Transfer
ChemBioChem, Volume 27, Issue 14, 29 July 2026.Electroactive microbe Shewanella oneidensis reduced non‐native electron transfer protein, azurin, via extracellular electron transfer (EET) with dependence on azurin redox potential. Utilizing azurin in EET‐driven bio‐(electro)catalysis improved fuel cell current and accelerated textile dye decolorization.

Evolution of electron transfer out of the cell: comparative genomics of six
BMC Genomics, 2010 Background Geobacter species grow by transferring electrons out of the cell - either to Fe(III)-oxides or to man-made substances like energy-harvesting electrodes.

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.Hydrogen gas can be produced from organic matter in microbial electrolysis cells (MECS) using certain microorganisms on the anode and a catalyst on the cathode. We show that materials and different electrode distances change gas production rates, but the intrinsic properties of the microbes to produce current were unaffected by subsequent changes in ...

Bacterias, fuente de energía para el futuro
Tecnura, 2012 This paper presents a family of bacteria called Geobacter that have the ability to produce power as a renewable source in a microbial fuel cell. These bacteria can completely oxidize organic compounds using different elements or substances as electron ...

European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.ABSTRACT Waterlogging of aerobic soils can induce microbially catalysed reductive dissolution of iron oxides and the subsequent mobilisation of associated carbon. Additionally, the resulting shift in microbial metabolism and community structure may eventually affect the accrual of microbially derived carbon into soils.

Global Change Biology, Volume 32, Issue 7, July 2026.Based on a global analysis of 1921 soil samples, we show that agricultural management acts as a powerful ecological filter reshaping microbial communities. Land use and inputs—pesticides and fertilizers—drive a functional shift toward opportunistic pathogens and fragmented, less connected microbial networks, potentially compromising soil ecosystem ...
