The Impact of Redox Mediators on the Electrogenic and Physiological Properties of Synechocystis sp. PCC 6803 in a Biophotovoltaic System

ChemSusChem, Volume 18, Issue 13, July 1, 2025.
Redox mediators are essential to promote the electrogenic activity of cyanobacteria in biophotovoltaics. In this work, we systematically evaluates three representative mediators about their influence on the cyanobacterial growth, photosynthetic efficiency, and electrogenic activity. The results reveal distinct impacts of different mediators, despite of

Molecular Underpinnings of Fe(III) Oxide Reduction by Shewanella Oneidensis MR-1 [PDF]

, 2012
In the absence of O2 and other electron acceptors, the Gram-negative bacterium Shewanella oneidensis MR-1 can use ferric [Fe(III)] (oxy)(hydr)oxide minerals as the terminal electron acceptors for anaerobic respiration.

A Membrane-Bound Cytochrome Enables Methanosarcina acetivorans To Conserve Energy from Extracellular Electron Transfer

mBio, 2019
Extracellular electron exchange in Methanosarcina species and closely related Archaea plays an important role in the global carbon cycle and enhances the speed and stability of anaerobic digestion by facilitating efficient syntrophic interactions.

Diverse Microorganisms in Sediment and Groundwater Are Implicated in Extracellular Redox Processes Based on Genomic Analysis of Bioanode Communities

Frontiers in Microbiology, 2020
Extracellular electron transfer (EET) between microbes and iron minerals, and syntrophically between species, is a widespread process affecting biogeochemical cycles and microbial ecology.

Electron Accepting Units of the Diheme Cytochrome c TsdA, a Bifunctional Thiosulfate Dehydrogenase/Tetrathionate Reductase [PDF]

, 2016
The enzymes of the thiosulfate dehydrogenase (TsdA) family are wide-spread diheme c-type cytochromes. Here, redox carriers were studied mediating the flow of electrons arising from thiosulfate oxidation into respiratory or photosynthetic electron chains.

Engineered Cell Elongation Promotes Extracellular Electron Transfer of Shewanella Oneidensis

Advanced Science, Volume 11, Issue 41, November 6, 2024.
This work investigates how cell elongation impacts the extracellular electron transfer of Shewanella oneidensis MR‐1 via genetic engineering to inhibit divisome formation. The electrophysiology of cell elongation is systematically elucidated in terms of intracellular generation, trans‐membrane transfer, and biofilm formation.

Heme ligation and redox chemistry in two bacterial thiosulfate dehydrogenase (TsdA) enzyme [PDF]

, 2019
Thiosulfate dehydrogenases (TsdA) are bidirectional bacterial di-heme enzymes that catalyze the interconversion of tetrathionate and thiosulfate at measurable rates in both directions.

Characterisation of Bone Beneficial Components from Australian Wallaby Bone. [PDF]

, 2016
Background: Osteoporosis is a condition in which the bones become brittle, increasing the risk of fractures. Complementary medicines have traditionally used animal bones for managing bone disorders, such as osteoporosis.
