متن کاملMass-independent Isotope Fractionation of Molybdenum and Ruthenium in Murchison
Introduction: Dauphas et al. [1] and Yin et al. [2] reported molybdenum isotopic anomalies in bulk undifferentiated and differentiated meteorites and this was the first time that isotopic anomalies were found on the scale of a meteorite hand-specimen. Even more recently, Chen and Papanastassiou [3,4] identified ruthenium isotopic anomalies in meteorites. Dauphas et al. [5] used theoretical prod...
متن کاملOceanic molybdenum isotope fractionation: Diagenesis and hydrothermal ridgeâ•’flank alteration
[1] Isotopic analyses of dissolved molybdenum are presented for sediment pore waters from a reducing sedimentary basin and for fluids from a low-temperature ridge flank hydrothermal system. dMo in these fluids range from 0.8 to 3.5% (relative to a laboratory standard), demonstrating that marine sedimentary reactions significantly fractionate Mo isotopes. Within the upper 3 cm of sediment, manga...
متن کاملHydrogen isotope fractionation during H
Hydrogen metabolism was studied in the anaerobic bacterium, Sporomusa sp. strain DMG 58, by measuring natural abundance levels of deuterium in H 2 , H 2 O, and individual fatty acids during acetogenic growth on H 2 / CO 2 . Four cultures were grown, each in medium with a distinct hydrogen-isotopic composition ( δ D-H 2 O). The δ D value of H 2 was quantified in the residual gas exiting the grow...
متن کاملMolybdenum isotope fractionation by cyanobacterial assimilation during nitrate utilization and N2fixation
We measured the δ⁹⁸Mo of cells and media from molybdenum (Mo) assimilation experiments with the freshwater cyanobacterium Anabaena variabilis, grown with nitrate as a nitrogen (N) source or fixing atmospheric N₂. This organism uses a Mo-based nitrate reductase during nitrate utilization and a Mo-based dinitrogenase during N₂ fixation under culture conditions here. We also demonstrate that it ha...
