Mechanistic stratification in electroactive biofilms of Geobacter sulfurreducens mediated by pilus nanowires
Electricity generation by Geobacter sulfurreducens biofilms grown on electrodes involves matrix-associated electron carriers, such as c-type cytochromes. Yet, the contribution of the biofilm's conductive pili remains uncertain, largely because pili-defective mutants also have cytochrome defects. Here we report that a pili-deficient mutant carrying an inactivating mutation in the pilus assembly ...

Nature Communications 7:12217 doi: 10.1038/ncomms12217 (2016); Published 2 Aug 2016; Updated 28 Apr 2017 Two previous studies (Vargas et al. 2013, Liu et al. 2014) reporting that conductive pili are required for long-range electron transport in Geobacter sulfurreducens were inadvertently omitted from the reference list of this Article, and should have been cited in the Introduction section wher...
متن کاملGeobacter sulfurreducens can grow with oxygen as a terminal electron acceptor.
Geobacter sulfurreducens, previously classified as a strict anaerobe, tolerated exposure to atmospheric oxygen for at least 24 h and grew with oxygen as the sole electron acceptor at concentrations of 10% or less in the headspace. These results help explain how Geobacter species may survive in oxic subsurface environments, being poised to rapidly take advantage of the development of anoxic cond...
متن کاملLong-range electron transport in Geobacter sulfurreducens biofilms is redox gradient-driven.
Geobacter spp. can acquire energy by coupling intracellular oxidation of organic matter with extracellular electron transfer to an anode (an electrode poised at a metabolically oxidizing potential), forming a biofilm extending many cell lengths away from the anode surface. It has been proposed that long-range electron transport in such biofilms occurs through a network of bound redox cofactors,...
متن کاملInvestigation of Electron Transfer by Geobacter sulfurreducens Biofilms by using an Electrochemical Quartz Crystal Microbalance
Both the short- and long-term electron-transfer processes of electrode-respiring Geobacter sulfurreducens biofilms are demonstrated by using an electrochemical quartz crystal microbalance (QCM). The QCM monitors the frequency shift from the initial resonant frequency (background) in real time, while the current increases, because of biofilm growth. In the short term, the frequency shift is line...
