Interactions between microbes and iron in the euphotic ocean
Iron (Fe) is an essential nutrient for all non-viral life. During the bulk of Earth’s history, Fe was abundant in the global oceans, but subsequent oxidation resulting in vanishingly low concentrations in much of the surface ocean. Microbes therefore had to evolve compensating mechanisms which have modern day geochemical and human health implications. I will present several recent or soon to be published studies examining Fe limitation of both photosynthetic and heterotrophic microbes in both field and laboratory studies, as well as genetic and genomic examinations of siderophore production by a model marine microbe.
