Journal ArticleDOI
Current Production and Metal Oxide Reduction by Shewanella oneidensis MR-1 Wild Type and Mutants
Orianna Bretschger,Anna Obraztsova,Carter A. Sturm,In Seop Chang,In Seop Chang,Yuri A. Gorby,Samantha B. Reed,David E. Culley,Catherine L. Reardon,Soumitra Barua,Soumitra Barua,Margaret F. Romine,Jizhong Zhou,Jizhong Zhou,Alexander S. Beliaev,Rachida Bouhenni,Daad A. Saffarini,Florian Mansfeld,Byung Hong Kim,Byung Hong Kim,James K. Fredrickson,Kenneth H. Nealson +21 more
TL;DR: The results showed that a few key cytochromes play a role in all of the processes but that their degrees of participation in each process are very different, suggesting a very complex picture of electron transfer to solid and soluble substrates by S. oneidensis MR-1.
Journal ArticleDOI
Sulfate-reducing bacterium grows with Cr(VI), U(VI), Mn(IV), and Fe(III) as electron acceptors
Bradley M. Tebo,Anna Obraztsova +1 more
TL;DR: This organism is the first sulfate-reducing bacterium described that can grow with metals or U(VI) as sole electron acceptors.
Journal ArticleDOI
Dissimilatory Metal Reduction by the Facultative Anaerobe Pantoea agglomerans SP1
TL;DR: To the authors' knowledge, this is the first mesophilic facultative anaerobe reported to couple acetate oxidation to dissimilatory metal reduction and most closely related to Pantoeaagglomerans, a member of the family Enterobacteriaceae within the gamma subdivision of the Proteobacteria.
Journal ArticleDOI
Current production and metal oxide reduction by Shewanella oneidensis MR-1 wild type and mutants (Applied and Environmental Microbiology (2007) 73, 21, (7003-7012))

Journal ArticleDOI
Electrokinesis is a microbial behavior that requires extracellular electron transport
Howard W. Harris,Mohamed Y. El-Naggar,Orianna Bretschger,Melissa J. Ward,Margaret F. Romine,Anna Obraztsova,Kenneth H. Nealson +6 more
TL;DR: Electrokinesis is defined as a behavioral response that requires functional extracellular electron transport that is observed as an increase in cell swimming speeds and lengthened paths of motion that occur in the proximity of a redox active mineral surface or the working electrode of an electrochemical cell.
