Journal ArticleDOI
Extracellular electron transfer via microbial nanowires.
Gemma Reguera,Kevin D. McCarthy,Teena Mehta,Julie S. Nicoll,Mark T. Tuominen,Derek R. Lovley +5 more
TL;DR: Results indicate that the pili of G. sulfurreducens might serve as biological nanowires, transferring electrons from the cell surface to the surface of Fe(iii) oxides, indicating possibilities for other unique cell-surface and cell–cell interactions, and for bioengineering of novel conductive materials.
Journal ArticleDOI
Extracellular electron transfer mechanisms between microorganisms and minerals
Liang Shi,Hailiang Dong,Gemma Reguera,Haluk Beyenal,Anhuai Lu,Juan Liu,Han-Qing Yu,James K. Fredrickson +7 more
TL;DR: The molecular mechanisms that underlie the ability of microorganisms to exchange electrons, such as c-type cytochromes and microbial nanowires, with extracellular minerals and with microorganisms of the same or different species are discussed.
Journal ArticleDOI
Biofilm and nanowire production leads to increased current in geobacter sulfurreducens fuel cells
Gemma Reguera,Kelly P. Nevin,Julie S. Nicoll,Sean F. Covalla,Trevor L. Woodard,Derek R. Lovley +5 more
TL;DR: Genetic studies demonstrated that efficient electron transfer through the biofilm required the presence of electrically conductive pili, which may represent an electronic network permeating the biofilms that can promote long-range electrical transfer in an energy-efficient manner, increasing electricity production more than 10-fold.
Journal ArticleDOI
Electroactive biofilms: Current status and future research needs
Abhijeet P. Borole,Gemma Reguera,Bradley R. Ringeisen,Zhi-Wu Wang,Yujie Feng,Byung Hong Kim,Byung Hong Kim +6 more
TL;DR: In this article, the effects of process and design parameters on the growth and activity of biofilms in bioelectrochemical systems (BESs) were assessed. And the relationship between electrochemical performance and operating parameters was examined to identify gaps in assessment and the potential role of future modeling efforts.
Journal ArticleDOI
Extracellular reduction of uranium via Geobacter conductive pili as a protective cellular mechanism.
TL;DR: A previously unrecognized role for Geobacter conductive pili in the extracellular reduction of uranium is demonstrated, and its essential function as a catalytic and protective cellular mechanism that is of interest for the bioremediation of uranium-contaminated groundwater is highlighted.
