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 کاملPossible nonconductive role of Geobacter sulfurreducens pilus nanowires in biofilm formation.
Geobacter sulfurreducens required expression of electrically conductive pili to form biofilms on Fe(III) oxide surfaces, but pili were also essential for biofilm development on plain glass when fumarate was the sole electron acceptor. Furthermore, pili were needed for cell aggregation in agglutination studies. These results suggest that the pili of G. sulfurreducens also have a structural role ...
متن کاملProtein immobilization onto electrochemically synthesized CoFe nanowires
CoFe nanowires have been synthesized by the electrodeposition technique into the pores of a polycarbonate membrane with a nominal pore diameter of 50 nm, and the composition of CoFe nanowires varying by changing the source concentration of iron. The synthesized nanowire surfaces were functionalized with amine groups by treatment with aminopropyltriethoxysilane (APTES) linker, and then conjugate...
متن کاملNanowires 4 . Nanowires
This chapter provides an overview of recent research on inorganic nanowires, particularly metallic and semiconducting nanowires. Nanowires are one-dimensional, anisotropic structures, small in diameter, and large in surfaceto-volume ratio. Thus, their physical properties are different than those of structures of different scale and dimensionality. While the study of nanowires is particularly ch...
