| Microorganisms and plants produce siderophores to facilitate the release of iron that would otherwise be unavailable1-5, and to instigate the mobilization of other nutrients and heavy metals. In this paper the author shows that the effect of siderophores on the sorption behavior of metals ions (Ca2+, Mg2+, Fe2+, Co2+, Sr2+, Ni2+, Cd2+, Zn2+, and Cu2+) can be predicted from the intrinsic affinity of metal ions for mineral surfaces. In this work the author proposes how siderophores may mediate mechanisms of nutrient release and complexation in natural porous media. |
