Journal ArticleDOI
Microorganisms pumping iron: anaerobic microbial iron oxidation and reduction
TL;DR: Biological iron apportionment has been described as one of the most ancient forms of microbial metabolism on Earth, and as a conceivable extraterrestrial metabolism on other iron-mineral-rich planets such as Mars.
Journal ArticleDOI
Anaerobic redox cycling of iron by freshwater sediment microorganisms.
TL;DR: The results indicate that the wetland sediments contained organisms such as Geobacter sp.
Journal ArticleDOI
A novel ecological role of the Firmicutes identified in thermophilic microbial fuel cells
Kelly C. Wrighton,Peter Agbo,Falk Warnecke,Karrie A. Weber,Eoin L. Brodie,Todd Z. DeSantis,Philip Hugenholtz,Gary L. Andersen,John D. Coates,John D. Coates +9 more
TL;DR: A previously unidentified functional role for Gram-positive bacteria in MFC current generation is revealed, revealing the importance of using a variety of molecular and culture-based methods to reliably characterize bacterial communities.
Journal ArticleDOI
Nitrogen loss from soil through anaerobic ammonium oxidation coupled to iron reduction
TL;DR: In this paper, the potential for anaerobic ammonium oxidation coupled to iron(III) reduction, known as Feammox, was investigated in tropical upland soils. And the results showed that Feammoxide can fuel nitrogen losses in ecosystems rich in poorly crystalline iron minerals with low or fluctuating redox conditions.
Journal ArticleDOI
Electrochemical stimulation of microbial perchlorate reduction.
J. Cameron Thrash,J. Ian Van Trump,Karrie A. Weber,Elisabeth Miller,Laurie A. Achenbach,John D. Coates +5 more
TL;DR: The results of these studies demonstrate that biological perchlorate remediation can be facilitated through the use of a cathode as the primary electron donor, and that continuous treatment in such a system approaches current industry standards.
