Iron meteorites can support the growth of acidophilic chemolithoautotrophic microorganisms.
Chemolithoautotrophy based on reduced inorganic minerals is considered a primitive energy transduction system. Evidence that a high number of meteorites crashed into the planet during the early period of Earth history led us to test the ability of iron-oxidizing bacteria to grow using iron meteorites as their source of energy. Here we report the growth of two acidophilic iron-oxidizing bacteria...
متن کاملEfficient oxidation of sulfides using a molybdenum(VI)–dioxo complex containing an benzimidazole ligand
For the first time, dioxomolybdenum(VI) complex with the general formula [MoO2L2] containing a N-O bidentate ligands (HL=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. Elemental analyses (carbon, hydrogen, nitrogen), FT-IR and Uv-Visble spectra and 1HNMR analysis agree well with the proposed stoicheiometry of the complex [MoO...

15 صفحه اولTopological Control on Silicates' Dissolution Kinetics.
Like many others, silicate solids dissolve when placed in contact with water. In a given aqueous environment, the dissolution rate depends on the composition and the structure of the solid and can span several orders of magnitude. Although the kinetics of dissolution depends on the complexities of both the dissolving solid and the solvent, a clear understanding of which structural descriptors o...
