  Background and aims: Imperata cylindrica (L.) P. Beauv. is a grass whose capacity to hyperaccumulate Fe and biomineralize jarosite has been proved in its natural habitat. Here we carried out an experiment to reproduce the Fe hyperacummulation under laboratory controlled conditions and a study to locate and identify the Fe compounds formed in the process. Methods: The experiment was conducted with plants cultivated in a hydroponic culture in Hoagland solution enriched with 300 mg/kg of Fe at pH 3 for 60 days. Samples were analyzed with mass spectrometry (ICP-MS) for its elemental analysis; with electronic microscopy (SEM, TEM) and energy dispersive X-ray (EDX) analysis to analyze the different organs, tissues and cell content; and with X-ray diffraction (XRD) to identify the possible biomineral production. Results: I. cylindrica specimens reached 4805, 7976.. Read More»
