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.

Bacteriohopanoid inventory of Geobacter sulfurreducens and Geobacter metallireducens

Organic Geochemistry, 2013
Geobacter spp. are ubiquitous prokaryotes in diverse sedimentary environments, coupling the oxidation of various carbon compounds with the reduction of metals, such as ferric iron. One specific attribute of such species, namely Geobacter metallireducens and Geobacter sulfurreducens, is their ability to synthesize hopanoids. Hopanoids are among the most

Desiccation Response of Geobacter sulfurreducens

ASME 2007 Summer Bioengineering Conference, 2007
Geobacter sulfurreducens is an electricity producing bacteria. It is used in bacterial fuel cells, microbial-based sensors, and catalytic surfaces for bioremediation. Further development of such applications requires stabilization and preservation of the bacteria as thin films on surfaces.

Extracellular Palladium Nanoparticle Production using Geobacter sulfurreducens

ACS Sustainable Chemistry & Engineering, 2013
Sustainable methods are needed to recycle precious metals and synthesize catalytic nanoparticles. Palladium nanoparticles can be produced via microbial reduction of soluble Pd(II) to Pd(0), but in previous tests using dissimilatory metal reducing bacteria (DMRB), the nanoparticles were closely associated with the cells, occupying potential reductive ...

Geobacter sulfurreducens strain engineered for increased rates of respiration

Metabolic Engineering, 2008
Geobacter species are among the most effective microorganisms known for the bioremediation of radioactive and toxic metals in contaminated subsurface environments and for converting organic compounds to electricity in microbial fuel cells. However, faster rates of electron transfer could aid in optimizing these processes. Therefore, the Optknock strain

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.

Anaerobes unleashed: Aerobic fuel cells of Geobacter sulfurreducens

Journal of Power Sources, 2011
Abstract One of the limitations of power generation with microbial fuel cells is that the anode must typically be maintained under anaerobic conditions. When oxygen is present in the anode chamber microorganisms oxidize the fuel with the reduction of oxygen rather than electron transfer to the anode.

The hydrogenases of Geobacter sulfurreducens: a comparative genomic perspective

Microbiology, 2005
The hydrogenase content of the genome of Geobacter sulfurreducens, a member of the family Geobacteraceae within the delta-subdivision of the Proteobacteria, was examined and found to be distinct from that of Desulfovibrio species, another family of delta-Proteobacteria on which extensive research concerning hydrogen metabolism has been conducted. Four [

Spatially Resolved Chemical Analysis of Geobacter sulfurreducens Cell Surface

ACS Nano, 2019
Geobacter sulfurreducens is of interest for the highest efficiency of power generation and extremely long extracellular electron transfer (EET) between the bacterium and electrodes. Despite more than 15 years of intensive molecular biological research, there is still no clear answer which molecules are responsible for these processes.

Кинетика восстановления метакрилата RMrd Geobacter sulfurreducens

IX Всероссийская Пущинская конференция «Биохимия, физиология и биосферная роль микроорганизмов»
Среди терминальных дыхательных редокс систем, восстанавливающих ненасыщенные органические соединения, особого внимания заслуживают периплазматические флавинсодержащие ферментные системы анаэробных грамотрицательных бактерий. Такие ферментные системы обнаружены у Geobacter sulfurreducens AM-1 (класс Deltaproteobacteria), Anaeromyxobacter dehalogenans ...
