H2 Kinetic Isotope Fractionation Superimposed by Equilibrium Isotope Fractionation During Hydrogenase Activity of D. vulgaris Strain Miyazaki

Frontiers in Microbiology, 2019
We determined 2H stable isotope fractionation at natural abundances associated with hydrogenase activity by whole cells of Desulfovibrio vulgaris strain Miyazaki F expressing a NiFe(Se) hydrogenase.

Preliminary Proof-of-Concept Testing of Novel Antimicrobial Heat-Conducting “Metallic” Coatings Against Biofouling and Biocorrosion

Frontiers in Microbiology, 2022
NiMo (nickel-molybdenum) and NiMo with embedded CeO2 nanoparticles (NPs; 100 nm) were tested as antimicrobial coatings (~15 μm thickness) on titanium (Ti) surfaces using an electrochemical process for heat exchanger applications onboard marine vessels ...

Aerobic Lineage of the Oxidative Stress Response Protein Rubrerythrin Emerged in an Ancient Microaerobic, (Hyper)Thermophilic Environment [PDF]

, 2016
Indexación: Web of Science; Scopus.Rubrerythrins (RBRs) are non-heme di-iron proteins belonging to the ferritin-like superfamily. They are involved in oxidative stress defense as peroxide scavengers in a wide range of organisms. The vast majority of RBRs,

Natural Products as the Modulators of Gut Microbiota: A Pool for the Development of New Treatment Against Obesity?

Food Frontiers, Volume 7, Issue 3, May 2026.
Natural compounds regulate gut microbiota by improving microbial balance and increasing probiotics, which boost short‐chain fatty acid production to alleviate insulin resistance and inflammation. Additionally, they stimulate appetite‐suppressing hormones through bile acid signaling, while inhibiting pathogenic bacteria to repair intestinal barrier ...

Formation of Thiosulfate from Sulfite byDesulfovibrio vulgaris [PDF]

Journal of Bacteriology, 1969
Crude extracts ofDesulfovibrio vulgarisreduced sulfite to sulfide. Ammonium sulfate fractionation of crude extracts separated a thiosulfate-forming system from sulfite- and thiosulfate-reductase activities. Further purification by sucrose density centrifugation separated the thiosulfate-forming system into two components, both of which were required ...

Redox-dependent rearrangements of the NiFeS cluster of carbon monoxide dehydrogenase

eLife, 2018
The C-cluster of the enzyme carbon monoxide dehydrogenase (CODH) is a structurally distinctive Ni-Fe-S cluster employed to catalyze the reduction of CO2 to CO as part of the Wood-Ljungdahl carbon fixation pathway.

Genome Editing Method for the Anaerobic Magnetotactic Bacterium Desulfovibrio magneticus RS-1. [PDF]

, 2018
Magnetosomes are complex bacterial organelles that serve as model systems for studying bacterial cell biology, biomineralization, and global iron cycling. Magnetosome biogenesis is primarily studied in two closely related Alphaproteobacteria of the genus

Extracellular Electron Transfer Is a Bottleneck in the Microbiologically Influenced Corrosion of C1018 Carbon Steel by the Biofilm of Sulfate-Reducing Bacterium Desulfovibrio vulgaris. [PDF]

PLoS ONE, 2015
Carbon steels are widely used in the oil and gas industry from downhole tubing to transport trunk lines. Microbes form biofilms, some of which cause the so-called microbiologically influenced corrosion (MIC) of carbon steels.

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 ...
