Bacterial Extracellular Electron Transfer Occurs in Mammalian Gut [PDF]

Analytical Chemistry, 2019
As a well-studied biochemical reduction process in environmental microbiology, extracellular electron transfer (EET) was recently discovered in bacteria closely related to human health, and orthologues of a flavin-based EET gene were found in the genomes of many species across Firmicutes, a major phylum in mammalian gut microbiota. However, EET has not

Flavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis

mBio, 2013
Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct

Structure of a bacterial cell surface decaheme electron conduit [PDF]

, 2011
Some bacterial species are able to utilize extracellular mineral forms of iron and manganese as respiratory electron acceptors. In Shewanella oneidensis this involves decaheme cytochromes that are located on the bacterial cell surface at the termini of ...

Characterization of an electron conduit between bacteria and the extracellular environment [PDF]

, 2009
A number of species of Gram-negative bacteria can use insoluble minerals of Fe(III) and Mn(IV) as extracellular respiratory electron acceptors. In some species of Shewanella, deca-heme electron transfer proteins lie at the extracellular face of the outer
