The article discusses a study related to the effect of nano-scale zero valent iron (NZVI) on metabolism of iron reducing bacteria (IRB). It notes that several tests have been performed on the interaction including high performance liquid chromatography (HPLC), ferrozine test, and colony forming ...
In this work we investigated the interactions between the nanoscale zero valent iron (nZVI) and iron reducing bacteria (IRB) during the remediation of trichloroethene (TCE). Dehalogenation of TCE was examined using nZVI NANOFER 25 (N25) and the Gram-negative bacterium Shewanella algae CCM 4595 ...

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 ...
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,...

Iron form: Plant iron (Fe3+) must be converted to the more absorbable form (Fe2+) in the small intestine, reducing overall bioavailability. Some of the best dietary sources of iron are: Red meat Mollusks Clams Mussels Oysters Octopus Whelk Note: To find out the status of your iron gro...
(phylum Chloroflexi) may reflect a tight coupling with Fe-reducing bacteria45; however, they are not considered to be a direct driver to change IC (Fig. 5d). Given the low temperatures at these sediment depths compared to where IC is normally observed, and the observed relationship between ...
