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

In Situ Spectroelectrochemical Characterization Reveals Cytochrome-Mediated Electric Syntrophy in Geobacter Coculture.

Environmental Science and Technology, 2021
Direct interspecies electron transfer (DIET) between microbial species prevails in some key microbial consortia. However, the electron transfer mechanism(s) in these consortia is controversial due to lack of efficient characterization methods.

Biomolecular Insights into Extracellular Pollutant Reduction Pathways of Geobacter sulfurreducens Using a Base Editor System.

Environmental Science and Technology, 2022
Geobacter species are critically involved in elemental biogeochemical cycling and environmental bioremediation processes via extracellular electron transfer (EET), but the underlying biomolecular mechanisms remain elusive due to lack of effective ...

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.

Decolorization of azo dyes by Geobacter metallireducens

Applied Microbiology and Biotechnology, 2012
Geobacter metallireducens was found to be capable of decolorizing several azo dyes with different structures to various extents. Pyruvate, ethanol, acetate, propionate, and benzoate could support 66.3 ± 2.6-93.7 ± 2.1 % decolorization of 0.1 mM acid red 27 (AR27) in 40 h.

On Electron Transport through Geobacter Biofilms

ChemSusChem, 2012
AbstractGeobacter spp. can form a biofilm that is more than 20 μm thick on an anode surface by utilizing the anode as a terminal respiratory electron acceptor. Just how microbes transport electrons through a thick biofilm and across the biofilm/anode interface, and what determines the upper limit to biofilm thickness and catalytic activity (i.e ...

Geobacter autogenically secreted fulvic acid to facilitate the dissimilated iron reduction and vivianite recovery.

Environmental Science and Technology, 2020
Biosynthetic organic matters, such as humus, play important roles in iron and phosphorus cycling in soil and aquatic systems. As an important member of humus, fulvic acid (FA) is ubiquitous in different environmental media, such as water, soil, and ...

Isolation of Geobacter species from diverse sedimentary environments

Applied and Environmental Microbiology, 1996
In an attempt to better understand the microorganisms responsible for Fe(III) reduction in sedimentary environments, Fe(III)-reducing microorganisms were enriched for and isolated from freshwater aquatic sediments, a pristine deep aquifer, and a petroleum-contaminated shallow aquifer.

Anaerobic Degradation of Chloroanilines by Geobacter sp. KT5

Current Microbiology, 2019
A chloroaniline-degrading bacterial strain isolated from polluted sediment in the Mekong River was identified as Geobacter sp. KT5. The obtained isolate was found to utilize a wide range of trichloroanilines (TCAs), dichloroanilines (DCAs), monochloroanilines (MACs), and aniline as sources of carbon and energy.
