Isotopic compositions of Mo and Fe measured by MC-ICP-MS indicate that during assimilation of Mo and Fe via nitrogen fixation by Azotobacter vindandii, the lighter isotope of Mo ( Mo versus Mo) is preferentially assimilated by the bacteria with a fractionation factor between assimilated and dissolved Mo of0.9997 [2]. In contrast, the heavier isotope of Fe ( Fe versus Fe) was removed from solution by the bacteria with a fractionation factor of 1.0011. Fractionation of Mo isotopes results from kinetic effects involving metal-binding ligands, whereas Fe... [Pg.355]
