Pili Expression in Geobacter sulfurreducens Lacking the Putative Gene for the PilB Pilus Assembly Motor

T. Ueki, D. J. Walker, K. P. Nevin, J. E. Ward, T. L. Woodard, S. S. Nonnenmann, D. R. Lovley

This paper shows that deleting the PilB gene in Geobacter sulfurreducens does not prevent e-pili expression, challenging previous assumptions about gene deletion strategies for studying e-pili function.

Syntrophus Conductive Pili Demonstrate that Common Hydrogen-Donating Syntrophs can have a Direct Electron Transfer Option

D. J. Walker, K. P. Nevin, D. E. Holmes, A.-E. Rotaru, J. E. Ward, T. L. Woodard, J. Zhu, T. Ueki, S. S. Nonnenmann, M. J. McInerney, D. R. Lovley

The paper shows that Syntrophus aciditrophicus can use direct interspecies electron transfer via conductive pili, challenging the belief that hydrogen/formate transfer is the primary mechanism in syntrophic communities.
