Tailoring Chemical Microenvironment of Iron‐Triad Electrocatalysts for Hydrogen Production by Water Electrolysis

Advanced Energy Materials, Volume 15, Issue 25, July 1, 2025.
Iron‐triad‐based materials are attracting attention for green hydrogen production via water electrolysis due to their favorable electronic and flexible chemical properties, enabling the tailoring of electrochemical performance. This review covers the basics of water electrolysis, challenges in catalyst evaluation, and recent advances in tuning iron ...

Possible role of Geobacter sulfurreducens in anaerobic corrosion of steels [PDF]

, 2007
Geobacteraceae are the most widespread microorganisms in soils and sediments in which microbial reduction of Fe(III) is an important process, either in the natural degradation of organic compounds or in their bioremediation.

Methanotrophic Flexibility of ‘Ca. Methanoperedens’ and Its Interactions With Sulphate‐Reducing Bacteria in the Sediment of Meromictic Lake Cadagno

Environmental Microbiology, Volume 27, Issue 7, July 2025.
In anoxic sediments of the meromictic freshwater Lake Cadagno ‘Ca. Methanoperedens’ and sulphate‐reducing Desulfobacterota QYQD01 co‐occur. Metagenomics revealed that ‘Ca. Methanoperedens’ genomes harbour different extracellular electron transfer pathways.

Elastic Deformation of Cellulose/Lignin‐Based Anode for Rejuvenating Aged Mix‐Cultured Electroactive Biofilms

Advanced Science, Volume 12, Issue 23, June 20, 2025.
A new strategy for revitalizing aged biofilms using the elastic deformation of biomass‐based flexible carbon aerogel is proposed. The elastic deformation removes the nonelectrogenic bacteria and the dead electrogenic bacteria, as well as a lot of loosely bound extracellular polymer materials.

Direct involvement of ombB, omaB, and omcB genes in extracellular reduction of Fe(III) by Geobacter sulfurreducens PCA [PDF]

, 2015
The tandem gene clusters orfR-ombB-omaB-omcB and orfS-ombC-omaC-omcC of the metal-reducing bacterium Geobacter sulfurreducens PCA are responsible for trans-outer membrane electron transfer during extracellular reduction of Fe(III)-citrate and ...

An argument for using anaerobes as microbial cell factories to advance synthetic biology and biomanufacturing

AIChE Journal, Volume 71, Issue 6, June 2025.
Abstract Anaerobes thrive in the absence of oxygen and are an untapped reservoir of biotechnological potential. Therefore, bioprospecting efforts focused on anaerobic microbial diversity could rapidly uncover new enzymes, pathways, and chassis organisms to drive biotechnology innovation.

Lack of physiological evidence for cytochrome filaments functioning as conduits for extracellular electron transfer

mBio
Extracellular cytochrome filaments are proposed to serve as conduits for long-range extracellular electron transfer. The primary functional physiological evidence has been the reported inhibition of Geobacter sulfurreducens Fe(III) oxide reduction when ...
