Direct Observation of Electrically Conductive Pili Emanating from Geobacter sulfurreducens

X. Liu, D. J. F. Walker, S. Nonnenmann, D. Sun, D. R. Lovley

This paper directly observes electrically conductive pili (e-pili) in Geobacter sulfurreducens using atomic force microscopy, confirming their role in long-range extracellular electron transport.

Cytochrome OmcS is not essential for long-range electron transport in Geobacter sulfurreducens strain KN400

D. J. F. Walker, Y. Li, D. Meier, S. Pinches, D. E. Holmes, J. A. Smith

This study shows that OmcS is not essential for long-range electron transport in G. sulfurreducens strain KN400, as its deletion does not impair Fe(III) oxide reduction or direct interspecies electron transfer.

The Archaellum of Methanospirillum hungatei is Electrically Conductive

D. J. F. Walker, E. Martz, D. E. Holmes, Z. Zhou, S. S. Nonnenmann, D. R. Lovley

The paper demonstrates that the archaellum of Methanospirillum hungatei is electrically conductive, identifying a core of phenylalanines as a potential electron-conducting pathway.

Electrically Conductive Pili from Pilin Genes of Phylogenetically Diverse Microorganisms

D. J. F. Walker, R. Y. Adhikari, D. E. Holmes, J. E. Ward, T. L. Woodard, K. P. Nevin, D. R. Lovley

This study expresses pilin genes from diverse microorganisms in Geobacter sulfurreducens to identify new sources of electrically conductive pili, finding that some produce e-pili with properties similar to native ones.
