TL;DR: In this paper, X-ray diffraction and electron microscopic analyses indicated that the Fe-rich material collected was predominantly ferrihydrite and poorly crystallized lepidocrocite, while the Mn-rich mixture was a mixture of poorly crystallised Mn oxyhydroxides.

TL;DR: Bacteria are very small (∼ 1.5 μm3) but have the largest surface area to volume ratio of any life form as mentioned in this paper, which is mainly due to the overall anionic charge of bacterial surfaces imparted by the macromolecules which make up their fabric.

TL;DR: The cycling of Fe in the lower portion of the tailings was mainly driven by the precipitation of melanterite (FeSO4.7H2O) following the oxidation of pyrite and the release of large amounts of dissolved Fe and SO42−.

TL;DR: The cell surface polymers of microorganisms readily bind a variety of metal ions, which enables the organisms to immobilize potentially toxic metal ions before they encounter the plasma membrane.

TL;DR: The tailings of the abandoned Kam Kotia mine, located near Timmins, Ontario, Canada, were studied to understand the role of bacteria in Fe cycling and local affected the cycling of Fe in the tailings by promoting the formation of small amounts of Fe-monosulfides.
