Linking NrfD/PsrC‐like architecture to energy conservation: Functional residues in the quinone reactive QrcABCD complex of sulfate‐reducing bacteria

Protein Science, Volume 35, Issue 5, May 2026.
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.

Membrane Vesicle Formation Removes Iron Sulfide Mineral Crusts From the Cell Surface of Growing Sulfate‐Reducing Bacteria

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT Sulfate‐reducing bacteria (SRB) drive the process of sulfate reduction in low‐temperature sedimentary environments. Through the production of sulfide, they promote the formation of iron‐sulfide (Fe‐S) minerals when Fe(II) is available. The negative charge of the cell surface of bacteria can promote the binding of Fe(II), leading to the ...

Comparison of different small molecular weight alcohols for sustaining sulfidogenic bioreactors maintained at moderately low pH

Frontiers in Bioengineering and Biotechnology, 2022
Sulfate-reducing bacteria (SRB) catalyse the dissimilatory reduction of sulfate to hydrogen sulfide using a wide range of small molecular weight organic compounds, and hydrogen, as electron donors.

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

Advanced Science, Volume 13, Issue 4, 19 January 2026.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide
