Linking NrfD/PsrC-like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate-reducing bacteria. [PDF]

Protein Sci
Abstract The QrcABCD quinone reductase complex is an electrogenic complex present in sulfate‐reducing bacteria of the Desulfobacterota phylum. It operates as a cytochrome c3:menaquinone oxidoreductase involved in electron transfer from periplasmic hydrogen or formate oxidation to the menaquinone (MK) pool.

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

ChemSusChem
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

Elastic Deformation of Cellulose/Lignin-Based Anode for Rejuvenating Aged Mix-Cultured Electroactive Biofilms. [PDF]

Adv Sci (Weinh)
A new strategy for revitalizing aged biofilms using the elastic deformation of biomass‐based flexible carbon aerogel is proposed. The elastic deformation removes the nonelectrogenic bacteria and the dead electrogenic bacteria, as well as a lot of loosely bound extracellular polymer materials.

Inactive "Ghost" Cells Do Not Affect Motility and Long-Range Electron Transport in Filamentous Cable Bacteria. [PDF]

Environ Microbiol
Mechanisms for the creation of individual ghost cells within a cable bacterium filament. (A) Schematic overview of different stressors that can lead to cell lysis or cell death. (i) Viral particles infect cells, (ii) predatory bacteria can attach to and infect a cable bacterium filament, (iii) ciliates depict bacterivory, and (iv) mechanical stress ...

Fine scale measurements in Belgian coastal sediments reveal different mobilization mechanisms for cationic trace metals and oxyanions

Environment International, 2020
Belgian coastal sediment serves as an important sink for trace elements, yet a systematic study covering a wide range of elements including redox-sensitive metals (Fe, Mn, and Co), cationic trace metals (Cd, Pb, Ni, Cu, and Zn), oxyanions (P, V, As, and ...

Disguised as a Sulfate Reducer: Growth of the Deltaproteobacterium Desulfurivibrio alkaliphilus by Sulfide Oxidation with Nitrate

mBio, 2017
This study demonstrates that the deltaproteobacterium Desulfurivibrio alkaliphilus can grow chemolithotrophically by coupling sulfide oxidation to the dissimilatory reduction of nitrate and nitrite to ammonium.

The proteomic differences and expression of fatty acid‐binding protein 6 (FABP6) associated with gastrointestinal injury in horses with oral administration of a clinical dose of phenylbutazone

Equine Veterinary Journal, Volume 58, Issue 3, Page 845-856, May 2026.
Abstract Background Phenylbutazone (PBZ) can potentially induce gastrointestinal ulceration, and early detection of PBZ‐induced gastroenteropathy will be useful for the diagnosis, treatment, and prevention of PBZ toxicity. Objectives To identify putative proteins associated with equine gastric ulcer syndrome after clinical dose (4.4 mg/kg ...

From the cytosol to the inner membrane: biogenesis of the mitochondrial carrier family

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Mitochondrial carrier proteins are essential for cellular physiology as they are active in a wide range of metabolic pathways including production of cellular energy, amino acid synthesis, redox balance and ion homeostasis. The double membrane of mitochondria provides a tightly gated environment through which carrier proteins facilitate the ...
