Anode biofilm transcriptomics reveals outer surface components essential for high density current production in Geobacter sulfurreducens fuel cells.

PLoS ONE, 2009
The mechanisms by which Geobacter sulfurreducens transfers electrons through relatively thick (>50 microm) biofilms to electrodes acting as a sole electron acceptor were investigated. Biofilms of Geobacter sulfurreducens were grown either in flow-through

Redox chemistry and acid-base equilibria of mitochondrial plant cytochromes c

, 1999
Mitochondrial cytochromes c from spinach, cucumber, and sweet potato have been investigated through direct electrochemical measurements and electronic and H-1 NMR spectroscopies, under conditions of varying temperature and pH.

Identification of a small tetraheme cytochrome c and a flavocytochrome c as two of the principal soluble cytochromes c in Shewanella oneidensis strain MR1.

, 2001
Two abundant, low-redox-potential cytochromes c were purified from the facultative anaerobe Shewanella oneidensis strain MR1 grown anaerobically with fumarate.

Extracellular organic disulfide reduction by Shewanella oneidensis MR-1

Microbiology Spectrum
Microbial reduction of organic disulfides affects the macromolecular structure and chemical reactivity of natural organic matter. Currently, the enzymatic pathways that mediate disulfide bond reduction in soil and sedimentary organic matter are poorly ...

Ligand-Protein Interactions in Cytochromes

, 2011
Cytochromes are found in all living beings and play an essential role in life processes. The two proteins studied in this thesis, cytochrome P450 carries out enzymatic reactions, metabolizes drugs, and synthesizes steroids while cytochrome c553 is a ...

A novel Geobacteraceae-specific outer membrane protein J (OmpJ) is essential for electron transport to Fe (III) and Mn (IV) oxides in Geobacter sulfurreducens

BMC Microbiology, 2005
Background Metal reduction is thought to take place at or near the bacterial outer membrane and, thus, outer membrane proteins in the model dissimilatory metal-reducing organism Geobacter sulfurreducens are of interest to understand the mechanisms of Fe ...

In situ spectroscopy reveals that microorganisms in different phyla use different electron transfer biomolecules to respire aerobically on soluble iron

Frontiers in Microbiology, 2016
Absorbance spectra were collected on twelve different live microorganisms, representing six phyla, as they respired aerobically on soluble iron at pH 1.5.

Extracellular electron uptake in Methanosarcinales is independent of multiheme c-type cytochromes [PDF]

, 2019
The co-occurrence of Geobacter and Methanosarcinales is often used as a proxy for the manifestation of direct interspecies electron transfer (DIET) in man-made and natural aquatic environments. We previously reported that not all Geobacter are capable of
