Zero-field and in-field Mossbauer investigations and electron paramagnetic resonance (EPR) measurements to follow the kinetics of the iron mineral formation by thermophilic dissimilatory anaerobic Fe(III)-reducing bacteria (strain Z-0001) and anaerobic alkaliphilic bacteria (strain Z-0531) were carried out.

Current Microbiology, 1996
The spent caustic wastewater from the oxidation of sulfide present in offshore natural gas production mainly comprises thiosulfate and sulfate. A biocatalytic process, employing phototrophic green sulfur bacteria in symbiosis with sulfate-reducing bacteria, is described in this paper for the production of sulfur from the spent caustic wastewater, with ...

Thiomicrospira strain CVO and Arcobacter strain FWKO B are two nitrate-reducing, sulfide-oxidizing bacteria (NR-SOB) isolated from the Coleville field in western Canada. Analysis by reverse sample genome probing (RSGP) indicates that both can be enriched from Coleville produced water samples by addition of nitrate. Neither could be enriched from waters

Desulfuromonas acetoxidans are uncoloured gram-negative sulfur bacteria that inhabit sulfur containing aquatic environments. These are gram-negative obligatory anaerobes that have an ability to reduce S 0 to H 2 S and Fe 3+ to Fe 2+ in the processes of dissimilation Sulfur- and Fe (III)-reduction.

Microscopic colitis (MC), a subtype of inflammatory bowel disease, is a chronic condition of unknown etiology. Recent evidence has linked MC with intriguing changes in the stool microbiota, which may be linked to disease pathogenesis. The composition of the mucosal microbiome in patients with MC remains unclear.We performed a cross-sectional study ...

Mercury-contaminated wastewater from industries such as chlor-alkali and battery industries, is a severe threat to aquatic ecosystems and must be treated before discharge. Theoretically, the sulfidogenic process is an ideal biotechnology for the low-cost treatment of mercury-contaminated wastewater because biogenic sulfide can precipitate inorganic ...

Synthesis and Reactivity in Inorganic, Metal-Organic, and Nano-Metal Chemistry, 2013
A series of cationic ammonium surfactants (1–3) and sulfonamides (4–5) were synthesized and characterized using elemental analysis and FT-IR spectroscopy. The nanostructures of the synthesized surfactants and sulfonamides as silver and zinc nanoparticles (Ag/ZnNPs) were prepared and characterized using transmission electron microscope. The TEM image of

Biology Bulletin, 2017
It was shown that in the conditions of organotrophic growth of colorless sulfur-reducing bacteria Sphaerotilus natans there was only one form of succinate dehydrogenase (SDH) and there were two in the mixotrophic type of nutrition. Three isoforms of SDH from S.

The importance of microbial metal reduction has been recently highlighted and studies on several microorganisms, which may serve as models, have been conducted. The use of Fe(III)-, sulfur- and sulfate-reducing bacteria provides challenges in the reduction of metals and radionuclides.
