Arsenic thiolation and the role of sulfate-reducing bacteria from the human intestinal tract [PDF]

, 2014
BACKGROUND: Arsenic (As) toxicity is primarily based on its chemical speciation. Although inorganic and methylated As species are well characterized in terms of metabolism and formation in the human body, the origin of thiolated methylarsenicals is still

Abcesso hepático e Bacteriemia Causada por Desulfovibrio Desulfuricans

Galicia Clínica
This case report presents a rare liver abscess caused by Desulfovibrio desulfuricans bacteremia in an elderly Indian patient. Desulfovibrio spp. are gram-negative, sulfate-reducing anaerobic bacteria that are typically found in the environment and can ...

Biomanufacture of nano-Pd(0) by Escherichia coli and electrochemical activity of bio-Pd(0) made at the expense of H2 and formate as electron donors [PDF]

, 2016
Objective: Palladised cells of Desulfovibrio desulfuricans and Shewanella oneidensis have been reported as fuel cell electrocatalysts but growth at scale may be unattractive/costly; we have evaluated the potential of using E.

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.

The Influence of Desulfovibrio Desulfuricans on Neptunium Chemistry [PDF]

MRS Proceedings, 1999
ABSTRACTBiotic Np(V) reduction is studied in light of its potential role for the environmental immobilization of this hazardous radionuclide. The speciation of Np inDesulfovibrio desulfuricanscultures is compared with Np speciation in the spent medium and in the uninoculated medium. Precipitates formed in all three samples.

Interaction of desulfovibrio desulfuricans biofilms with stainless steel surface and its impact on bacterial metabolism [PDF]

, 2006
Aims: To study the influence of some metallic elements of stainless steel 304 (SS 304) on the development and activity of a sulfate-reducing bacterial biofilm, using as comparison a reference nonmetallic material polymethylmethacrylate (PMMA).

Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

Angewandte Chemie International Edition, EarlyView.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

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.
