Reduction of Ferrum (III) by sulfate reducing and sulfur reducing bacteria
Біологічні студії, 2012 During growth in medium with 3.5 mM Fe(III), the biomass and hydrogen sulfide formation level by isolated from technogenic reservoir of Yavoriv sulfur deposit bacteria Desulfovibrio desulfuricans IMV K-6 and Desulfuromonas acetoxidans decreased nearly ...

Isolation of Sulfur Reducing and Oxidizing Bacteria Found in Contaminated Drywall [PDF]
International Journal of Molecular Sciences, 2010 Drywall from China has been reported to release sulfur producing products which are corrosive to metals, result in noxious odors, and represent a significant health risk. It has been reported that these emissions produce medical symptoms such as respiratory or asthma type problems, sinusitis, gastrointestinal disorders, and vision problems in home ...

Influence of short-term changes in dietary sulfur on the relative abundances of intestinal sulfate-reducing bacteria [PDF]
Gut Microbes, 2019 High-protein diets may be linked to gut inflammation due to increased production of hydrogen sulfide (H2S), a potential toxin, as an end product of microbial fermentation in the colon by sulfidogenic sulfate-reducing bacteria (SRB).

Syntrophic growth of sulfate-reducing bacteria and colorless sulfur bacteria during oxygen limitation [PDF]
FEMS Microbiology Ecology, 2006 Stable co-cultures of the sulfate-reducing bacterium Desulfovibrio desulfuricans PA2805 and the colorless sulfur bacterium Thiobacillus thioparus T5 were obtained in continuous cultures supplied with limiting amounts of lactate and oxygen while sulfate was present in excess.

Oxidation of Reduced Inorganic Sulfur Compounds by Bacteria: Emergence of a Common Mechanism? [PDF]
Applied and Environmental Microbiology, 2001 Biological oxidation of hydrogen sulfide to sulfate is one of the major reactions of the global sulfur cycle. Reduced inorganic sulfur compounds (referred to below as sulfur) are exclusively oxidized by prokaryotes, and sulfate is the major oxidation product.

Stable carbon isotope fractionation by acetotrophic sulfur-reducing bacteria [PDF]
FEMS Microbiology Ecology, 2009 Acetate is the most important intermediate in anaerobic degradation of organic matter. The carbon isotope effects associated with the oxidation of acetate (epsilon(ac)) were examined for four acetotrophic sulfur reducers, Desulfuromonas acetoxidans, Desulfuromonas thiophila, Desulfurella acetivorans, and Hippea maritima.

Attenuation of acid rock drainage by stimulating sulfur-reducing bacteria [PDF]
Environmental Earth Sciences, 2023 AbstractIron-sulfide minerals found in shale formations are stable under anaerobic conditions. However, in the presence of oxygen and water, acid-loving chemolithotrophic bacteria can transform the iron-sulfide minerals into a toxic solution of sulfuric acid and dissolved iron and minerals known as acid rock drainage (ARD).
