What is it about?

Despite Re having no known biological role, marine macroalgae concentrate Re to several orders of magnitude relative to seawater. This study demonstrates that Re abundance varies within the macroalgae and that Re is not located in specific structures, or held within chloroplasts or cytoplasmic proteins. Moreover, a positive correlation is shown between Re concentration in doped seawater and the abundance of Re accumulated in the tips of the macroalgae. Additionally, metabolically inactivated F. vesiculosus does not accumulate Re in oxic conditions, indicating that Re uptake is via syn-life bioadsorption/bioaccumulation and macroalgae may provide a source for Re phytomining and/or bioremediation.
