Ferrous hydroxy carbonate is a stable transformation product of biogenic magnetite

An ~1:1 mixture of ferrihydrite and nanocrystalline akaganeite (β-FeOOH; 10–15 nm) was incubated with Shewanella putrefaciens (strain CN32) under anoxic conditions with lactate as an electron donor and anthraquinone-2,6-disulfonate (AQDS) as an electron shuttle. The incubation was carried out in a 1,4-piperazinediethanesulfonic acid (PIPES)-buffered medium, without PO4 at circumneutral pH. Iron...

Big discovery for biogenic magnetite.

O ne of the most significant characteristics of the Anthropocene (the present age of geologic time) is the rate at which humans are perturbing the global carbon cycle. The potency of carbon dioxide and methane as greenhouse gases and their effects on Earth’s temperature balance is well established (1), and the myriad of climate and ecological changes and feedbacks in response to this abrupt war...

On the Aging of Ferrous Hydroxide and Ferrous Carbonate

Interest in the aging of metal hydroxide has increased greatly during the past few years and it is due, no doubt, mainly to the fact that certain metal hydroxides have become useful for the isolation of enzymes and vitamins. The selective adsorption properties of these hydroxides, aluminum hydroxide for example, make them suitable for these purposes. Their surface forces make it possible to sep...

Controlled cobalt doping in biogenic magnetite nanoparticles.

Cobalt-doped magnetite (CoxFe3 -xO4) nanoparticles have been produced through the microbial reduction of cobalt-iron oxyhydroxide by the bacterium Geobacter sulfurreducens. The materials produced, as measured by superconducting quantum interference device magnetometry, X-ray magnetic circular dichroism, Mössbauer spectroscopy, etc., show dramatic increases in coercivity with increasing cobalt c...
