Journal ArticleDOI
Anaerobic, Nitrate-Dependent Oxidation of Pyrite Nanoparticles by Thiobacillus denitrificans
TL;DR: Evidence is provided for the capability of Thiobacillus denitrificans to anaerobically oxidize a putatively nanosized pyrite particle fraction with nitrate as electron acceptor to substantiate a further "missing lithotrophy" in the global cycles of sulfur and iron and emphasizes the high reactivity of nanominerals in the environment.
Journal ArticleDOI
Transport of Ferrihydrite Nanoparticles in Saturated Porous Media: Role of Ionic Strength and Flow Rate
TL;DR: Experimental results indicate that, for usual ionic strength in European aquifers, under natural flow condition ferrihydrite nanoparticles are likely to be transported for 5 to 30 m, and a simple relationship is proposed for the estimation of travel distance with changing flow rate and ionsic strength.
Journal ArticleDOI
Long-distance electron transfer by cable bacteria in aquifer sediments.

TL;DR: Primary evidence is provided that sulfur-oxidizing cable bacteria can also be found at oxic–anoxic interfaces in aquifer sediments, where they provide a means for the direct recycling of sulfate by electron transfer over 1–2-cm distance.
Journal ArticleDOI
Nanosized Iron Oxide Colloids Strongly Enhance Microbial Iron Reduction
TL;DR: In this paper, the role of colloidal iron oxides in microbial iron reduction was studied and it was found that the colloidal oxides were reduced up to 2 orders of magnitude more rapidly (up to 1,255 pmol h 1 cell 1 ) than bulk macroaggregates of the same iron phases.
Journal ArticleDOI
Iron oxide nanoparticles in geomicrobiology: from biogeochemistry to bioremediation.
TL;DR: Focus is given to the transport behavior of Fe oxides in laboratory systems and in the environment, because of the high affinity of different contaminants to Fe oxide surfaces and associated co-transport of pollutants.
