iron reducing bacteriairon ore cavesbiospeleogenesisShewanella oneidensis MR-1cangairon orebanded iron formationsThe iron mining regions of Brazil contain thousands of "iron ore caves" (IOCs) that form within Fe(III)-rich deposits. The mechanisms by which these IOCs form remain unclear, but the...
Most probable number (MPN) analysis for Fe-reducing bacteria indicated they were present, typically around 103 cells . ml1, but composed well under 1% of the total bacterial population. A novel, obligately anaerobic Fe-reducing bacterium, Geothermobacter, strain HR-1, was isolated from one of ...
1)Iron bacteria铁细菌 1.Aiming at the three harmful microbes (sulfate reducing bacteria, iron bacteria and saprophytic bacteria) within oilfield water, this paper illustrates disadvantage and advantage of the two testing methods including checker vanishing dilution method and culture microscope check.针对...
Binding of iron to the CHASE4 domain of IsmP inhibits the IsmP-ImcA interaction, which leads to increased c-di-GMP synthesis by ImcA, thus promoting biofilm formation and reducing bacterial motility. Structural characterization of the apo-CHASE4 domain and its binding to iron allows us to pin...
Reducing the amount of carbon to 0.002–2.1% produces steel, which may be up to 1000 times harder than pure iron. A great variety of steel articles can then be made by cold working, hot rolling, forging, machining, etc. Removing the impurities from pig iron, but leaving 2–4% carbon,...
The trend in increasing aqueous Fe2+and DOC concentrations observed across the thaw gradient goes hand in hand with a significant increase in abundance of Fe(III)-reducing bacteria in the organic horizon from palsa to fen (unpairedt-test,N = 7,α = 0.05,p = 0.0001) and a ...
It has been shown that in bacteria, yeast, and some plants under stressful conditions, cells will induce iron sparing programmes, reducing the production of some iron-containing proteins while prioritising others, often orchestrated at the transcriptional level73,76,77,78. Our findings provide the ...
the co-occurrence networks revealed a notable decrease in negative interactions among soil bacteria, particularly among rare taxa. These findings suggest that changes of iron availability play an important role in shaping the bacterial community dynamics, enhancing cooperation while reducing competition. Alt...
In the process of microbial oil recovery, different reservoirs also have certain requirements for strains. There are many iron-reducing bacteria reported so far, but there are very few iron-reducing bacteria separated from oil reservoirs, and functional characteristics of the microorganismTessaracoccus ...
