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

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 ...

Smart REASSURED Sensors via Machine‐Augmented Printable On‐Paper Arrays

Advanced Sensor Research, EarlyView.
This perspective highlights the emerging role of pattern‐recognition, printable on‐paper sensor arrays for intelligent PoC diagnostics. It discusses how paper's inherent limitations can be overcome through surface modification and scalable printing, and how machine‐learning analysis of cross‐reactive arrays enables multiplexed, low‐cost, and REASSURED ...

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 ...

Rabbit Heart Cytochrome c

Journal of Biological Chemistry, 1966
Abstract The amino acid sequence of rabbit heart cytochrome c has been determined from the complete amino acid sequences of the chymotryptic peptides and the compositions of the tryptic peptides. This primary structure, as well as the properties of the protein, shows that rabbit heart cytochrome c is typically of the "mammalian type." The rabbit ...

Correlation of structure and function in the oxidative phosphorylation system of submitochondrial particles [PDF]

, 1969
1. After the centrifugation of sonicated heavy beef heart mitochondria at 75, 000 × g for 10 minutes, the supernatant was centrifuged at 144, 000 × g for 30 minutes. The residue was revealed being composed of vesicular inner membrane fragments (

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

Advanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

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.

Supercapacitors Based on c‐ Type Cytochromes Using Conductive Nanostructured Networks of Living Bacteria [PDF]

, 2012
Supercapacitors have attracted interest in energy storage because they have the potential to complement or replace batteries. Here, we report that c ‐type cytochromes, naturally immersed in a living, electrically conductive microbial biofilm, greatly ...
