Anode respiration-dependent biological nitrogen fixation by Geobacter sulfurreducens

Water Research, 2022
The present nitrogen fixation industry is usually energy-intensive and environmentally detrimental. Therefore, it is appealing to find alternatives. Here, we achieved both a synchronized biological nitrogen fixation and electric energy production by using Geobacter sulfurreducens in a microbial electrochemical system.

Reduction of palladium and production of nano-catalyst by Geobacter sulfurreducens

Applied Microbiology and Biotechnology, 2012
The present study is the first report on the ability of Geobacter sulfurreducens PCA to reduce Pd(II) and produce Pd(0) nano-catalyst, using acetate as electron donor at neutral pH (7.0 ± 0.1) and 30 °C. The microbial production of Pd(0) nanoparticles (NPs) was greatly enhanced by the presence of the redox mediator, anthraquinone-2,6-disulfonate (AQDS)

Microbial Reduction of Arsenic-Doped Schwertmannite by Geobacter sulfurreducens

Environmental Science & Technology, 2012
The fate of As(V) during microbial reduction by Geobacter sulfurreducens of Fe(III) in synthetic arsenic-bearing schwertmannites has been investigated. During incubation at pH7, the rate of biological Fe(III) reduction increased with increasing initial arsenic concentration.

Characterization of mercury protein targets in Geobacter sulfurreducens PCA

Talanta
Fe-reducing bacteria (FRB) play a pivotal role in regulating the biogeochemical cycling of mercury (Hg) and its associated ecological risks, while a systematic understanding of the molecular targets affected by Hg stress in these bacteria remain limited.

Metabolic Efficiency of Geobacter sulfurreducens Growing on Anodes with Different Redox Potentials

Current Microbiology, 2014
Microorganisms respiring Fe(III) in the environment face a range of redox potentials of the prospective terminal ferric electron acceptors, because Fe(III) can be present in different minerals or organic complexes. We investigated the adaptation of Geobacter sulfurreducens to this range by exposing the bacteria to different redox potentials between the

Significance of a minor pilin PilV in biofilm cohesion of Geobacter sulfurreducens

Science of The Total Environment
Bacterial adhesion plays a vital role in forming and shaping the structure of electroactive biofilms that are essential for the performance of bioelectrochemical systems (BESs). Type IV pili are known to mediate cell adhesion in many Gram-negative bacteria, but the mechanism of pili-mediated cell adhesion of Geobacter species on anode surface remains ...

Mutational Analysis of Geopilin Function in Geobacter Sulfurreducens

2011
Geobacter sulfurreducens possesses type IV pili that are considered to be conductive nanowires and a crucial structural element in biofilm formation, enabling electron transfer to insoluble metal oxides in anaerobic sediments and to graphite anodes in microbial fuel cells. The molecular mechanism by which electrons are transferred through the nanowires
