Electrobiocorrosion by Microbes without Outer-Surface Cytochromes

D. E. Holmes, T. L. Woodard, J. A. Smith, F. Musat, D. R. Lovley

This study identifies which methanogens and acetogens can perform electrobiocorrosion without outer-surface cytochromes, showing multiple strategies for electron transfer to Fe0.

Detrimental Impact of a Type VI Secretion System on Direct Interspecies Electron Transfer

J. A. Smith, D. E. Holmes, T. L. Woodard, Y. Li, X. Liu, L.-Y. Wang, D. Meier, I. A. Schwarz, D. R. Lovley

This study shows that the type VI secretion system in Geobacter metallireducens affects DIET by altering gene expression and electron transfer efficiency.

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.

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.

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.
