A novel, spore-forming, acidophilic and metal-resistant sulfate-reducing bacterium, strain OL T , was isolated from a microbial mat in tailing dam at gold ore mining site. Cells were slightly curved immotile rods, 0.5 µm diameter 2.0–3.0 long. stained Gram-negative, despite the Gram-positive cell structure revealed by electron microscopy of ultrathin layers. grew pH 4.0–7.0 with an optimum 5.5. utilised H 2 lactate, pyruvate, malate, formate, propionate, ethanol, glycerol, glucose, fructose,...
This study explores the phase composition, local atomic structure, and magnetic properties of biogenic nanomaterials synthesized through microbially mediated biomineralization by sulfate-reducing bacterium Desulfovibrio species strain A2 (Cupidesulfovibrio). Using X-ray diffraction (XRD), transmission electron microscopy (TEM), Mössbauer spectroscopy, absorption near-edge structure (XANES) extended fine (EXAFS) measurements, we identified a mixture vivianite (Fe3(PO4)2·8H2O)...
The diversity and activity of sulfate-reducing bacteria (SRB) in the camel gut remains largely unexplored. An abundant SRB community has been previously revealed feces Bactrian camels (Camelus bactrianus). This study aims to combine 16S rRNA gene profiling, sulfate reduction rate (SRR) measurement with a radioactive tracer, targeted cultivation shed light on gut. Fresh 55 domestic grazing freely semi-arid mountain pastures Kosh-Agach district Russian Altai area were analyzed. Feces sampled...
Desulfosporosinus metallidurans can be utilized in advanced water purification methods and for recovering phosphorus from industrial waste sludge.
Sulphate-reducing bacteria, primarily Desulfovibrio, are responsible for the active generation of H2S in swine production waste. The model species sulphate reduction studies, Desulfovibrio vulgaris strain L2, was previously isolated from manure characterized by high rates dissimilatory reduction. source electron acceptors low-sulphate waste rate formation remains uncertain. Here, we demonstrate ability L2 to use common animal farming supplements including L-lysine-sulphate, gypsum and...
The sulphate-reducing bacteria (SRB) of genus Desulfovibrio are a group prokaryotes associated with autism spectrum disorders (ASD). connection between the elevated numbers in gut children ASD compared healthy remains unresolved. A conceivable consequence SRB overgrowth is conversion bioavailable iron into low-soluble crystalline sulphides, causing deficiency organism. In this study, we report draft genome sequence and physiological features first cultivable isolate from patient ASD,...
Burning coal seams, characterized by massive carbon monoxide (CO) emissions, the presence of secondary sulfates, and high temperatures, represent suitable environments for thermophilic sulfate reduction. The diversity activity dissimilatory reducers in these remain unexplored. In this study, using metagenomic approaches, situ measurements with a radioactive tracer, cultivation we have shown that members genus Desulfofundulus are responsible extremely reduction rate (SRR) burning lignite...
Background . Nowadays many efforts are taken in searching for Parkinson’s disease biomarkers, especially an early recognition of the disease. The gut microbiota is one potential sources changes composition which PD actively studied. aim this study to identify biomarkers with estimated accuracy diagnostics, including differential relative other neurological diseases patients Russian population. Material and methods One hundred ninety-two metagenomics profiles from (n = 93), people diagnoses...
Adenosine, endogenous purine nucleoside, is an ATP metabolite that also acts as extracellular signaling molecule. The concentration of adenosine rises during hypoxia and cell damage leading to numerous pleiotropic effects. Although a high was found at burn injury, the effect has not been well elucidated. We have studied human peripheral blood myeloid cell, due their expression specific receptors capacity migrate site injury. shown cells after 72 hours stimulation develop altered surface...
Crystalline phases in biogenic sediments formed by Desulfotomaculum sp. DPr and Desulfovibrio KZ1 from geothermal sources were studied. Marcasite (FeS2), melnikovite (FeSххH2O) greigite (Fe3S4) detected. Composition of the crystalline phase depends on physicochemical conditions environment. The association crystals with cell surface, membranes periplasmic space was revealed. Intracellular crystallization presumably involves systems responsible for transport or cation chelation.
