Journal ArticleDOI
Nanominerals, Mineral Nanoparticles, and Earth Systems
Michael F. Hochella,Steven K. Lower,Patricia A. Maurice,R. Lee Penn,Nita Sahai,Donald L. Sparks,Benjamin S. Twining +6 more
TL;DR: This work has established that variations in surface and near-surface atomic structure as a function of size in this smallest of size regimes may make a difference in important geochemical and biogeochemical reactions and kinetics in minerals.
Journal ArticleDOI
Bacterial Recognition of Mineral Surfaces: Nanoscale Interactions Between Shewanella and α-FeOOH
TL;DR: Specific signatures in the force curves suggest that a 150-kilodalton putative iron reductase is mobilized within the outer membrane of S. oneidensis and specifically interacts with the goethite surface to facilitate the electron transfer process.
Journal ArticleDOI
Measuring interfacial and adhesion forces between bacteria and mineral surfaces with biological force microscopy
TL;DR: In this article, the authors measured the interfacial and adhesion forces between living, unmodified bacterial cells (Escherichia coli) and mineral surfaces (muscovite, goethite, and graphite) directly measured in aqueous solution using a force microscope.
Journal ArticleDOI
Specific Bonds between an Iron Oxide Surface and Outer Membrane Cytochromes MtrC and OmcA from Shewanella oneidensis MR-1
Brian H. Lower,Liang Shi,Ruchirej Yongsunthon,Timothy C. Droubay,David E. McCready,Steven K. Lower +5 more
TL;DR: There is a strong correlation between the whole-cell and pure-protein force spectra, suggesting that the unique binding attributes of each cytochrome complement one another and allow both MtrC and OmcA to play a prominent role in the transfer of electrons to Fe(III) in minerals.
Journal ArticleDOI
Antibody Recognition Force Microscopy Shows that Outer Membrane Cytochromes OmcA and MtrC Are Expressed on the Exterior Surface of Shewanella oneidensis MR-1
Brian H. Lower,Ruchirej Yongsunthon,Liang Shi,Linda Wildling,Hermann J. Gruber,Nicholas S. Wigginton,Catherine L. Reardon,Grigoriy E. Pinchuk,Timothy C. Droubay,Jean-François Boily,Steven K. Lower +10 more
TL;DR: Antibody recognition force microscopy showed that OmcA and MtrC are expressed on the exterior surface of living Shewanella oneidensis MR-1 cells when Fe(III), including solid-phase hematite (Fe2O3), was the terminal electron acceptor.
