Intracellular Hg(0) Oxidation in Desulfovibrio desulfuricans ND132 [PDF]

Environmental Science & Technology, 2016
The disposal of elemental mercury (Hg(0)) wastes in mining and manufacturing areas has caused serious soil and groundwater contamination issues. Under anoxic conditions, certain anaerobic bacteria can oxidize dissolved elemental mercury and convert the oxidized Hg to neurotoxic methylmercury.

Structure of rubredoxin from the bacterium Desulfovibrio desulfuricans [PDF]

FEBS Letters, 1986
The X‐ray crystallographic structure of rubredoxin from Desulfovibrio desulfuricans strain 27774 is described. This molecule is 15% smaller than previously studied rubredoxins, lacking a seven‐residue loop of chain but containing a histidine and a free‐sulfhydryl cysteine.

The ability of sulfate-reducing bacteria Desulfovibrio desulfuricans Ya-11 i Desulfobacter sp. to use nitrate as electron acceptor

Біологічні студії, 2011
The ability of Desulfovibrio desulfuricans Ya-11 bacteria to use nitrate as terminal electron acceptor was studied. The level of biomass accumulation in the medium with nitrate changed depending on the initial NO3– concentration. At nitrate concentration

Catalase and superoxiddismutase activities in Desulfovibrio desulfuricans Ya-11 under the influence of heavy metals salts

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2010
The highest catalase activity (42.67×10–2 µM×min–1×mg–1 of protein) in the cells of Desulfovibrio desulfuricans Ya-11 has been observed under the prolonged Pb(NO3)2 influence. In the presence of other heavy metals’ salts it has been changed in dependence

Formation of biologically influenced palladium microstructures by Desulfovibrio desulfuricans and Desulfovibrio ferrophilus IS5

New Biotechnology, 2022
A range of Desulfovibrio spp. can reduce metal ions to form metallic nanoparticles that remain attached to their surfaces. The bioreduction of palladium (Pd) has been given considerable attention due to its extensive use in areas of catalysis and electronics and other technological domains.

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
