• Potential for Microscale Bacterial Fe Redox Cycling at the Aerobic-Anaerobic Interface (2004, background): “Thamdrup, Fossing, and Jorgensen 1994), although the potential for substantial organic carbon oxidation coupled to direct enzymatic Fe(III) oxide reduction in marine sediments is now recognized (Thamdrup 2000).”
• Mercury Methylation from Unexpected Sources: Molybdate-Inhibited Freshwater Sediments and an Iron-Reducing Bacterium (2006, background): “Dissimilatory iron reduction is becoming increasingly recognized as an influential process in certain anomalous iron-rich marine sediments and in iron-rich freshwater sediments in general, where up to 50 to 70% of buried organic carbon can be oxidized via this process (30, 56, 63).”
• Anaerobic Metabolism: Linkages to Trace Gases and Aerobic Processes (2003, background): “About 35% of the iron and 75% of the manganese in soils and sediments is in the form of free oxides (Canfield, 1997; Cornell and Schwertmann, 1996; Thamdrup, 2000).”
• Influence of Biogenic Fe(II) on Bacterial Crystalline Fe(III) Oxide Reduction (2002, positive): “The microbiology and environmental signi cance of bacterial Fe(III) oxide reduction have been extensively reviewed over the last 10 years (Lovley 1991; Nealson and Myers 1991; Lovley 1992; Burdige 1993; Nealson and Saffarini 1994; Lovley 1995; Fredrickson and Gorby 1996; Lovley 2000; Thamdrup 2000).”
• Microbial reduction of metals and radionuclides. (2003, background): “The environmental relevance of Fe(III) and Mn(VI) reduction has been well documented [12,13].”
• Reduction of Actinides and Fission Products by Fe(III)-Reducing Bacteria (2002, background): “It is apparent from this Ž gure that the standard redox potential of ferrihydrite/Fe2C (approximately 0 V (Thamdrup 2000)) is more electronegative than the potentials for Pu(V)/Pu(IV), Np(V)/Np(IV) and U(VI)/U(IV).”
• Microbial electron transport and energy conservation – the foundation for optimizing bioelectrochemical systems (2015, background): “For the organic chelate complex Fe(III)citrate/Fe(II)-citrate the solubility is higher and, respectively, the midpoint potential (+372 mV; Thamdrup, 2000; Straub et al., 2001).”
• In search of the dead zone: Use of otoliths for tracking fish exposure to hypoxia (2015, neutral): “Unlike iron, which has comparatively faster oxidation kinetics, dissolved Mn may remain in solution for periods of days at a time, even in the presence of oxygen (Pakhomova et al., 2007; Thamdrup, 2000).”
• Fe(III) mineral formation and cell encrustation by the nitrate‐dependent Fe(II)‐oxidizer strain BoFeN1 (2005, background): “The observed formation of nitrite during nitratedependent Fe(II) oxidation but not during nitrate-dependent acetate oxidation might be a consequence of the entry of electrons from the redox couples ‘Fe(OH)3’/Fe and CO2/ acetate at different standard redox potentials (∼0 mV vs. −290 mV; Thauer et al.”
• Use of Ferric and Ferrous Iron Containing Minerals for Respiration by Desulfitobacterium frappieri (2003, methodology): “…coupled to nitrate reduction, the Gibbs free energy for this reaction was calculated using the actual concentrations of substrates and products in the cultures and a redox potential of+430 mM for the NO3−/NO2− couple (Thauer et al. 1977) and−385 mV for Fe(II)-NTA/Fe(III)NTA couple (Thamdrup 2000).”
• The Biogeochemical Sulfur Cycle of Marine Sediments (2019, background): “Iron reduction is limited by the reactivity of Fe(III) minerals, by the availability of electron donors, or a combination of both (Postma and Jakobsen, 1996; Thamdrup, 2000).”
• Formation of Cell-Iron-Mineral Aggregates by Phototrophic and Nitrate-Reducing Anaerobic Fe(II)-Oxidizing Bacteria (2009, background): “…significantly affects many other biogeochemical cycles (e.g. carbon, phosphorous, sulfur) and influences the mobilization, immobilization and transformation of organic and inorganic pollutants (Stumm and Sulzberger 1992; Thamdrup 2000; Cornell and Schwertmann 2003; Neubauer et al. 2007).”
• Control by fiddler crabs (Uca vocans) and plant roots (Avicennia marina) on carbon, iron, and sulfur biogeochemistry in mangrove sediment (2006, background): “The absence of Fe2+ in the upper few cm of the sediment must be caused by rapid reoxidation and precipitation as amorphous FeOOH (Thamdrup 2000; Canfield et al. 2005).”
