Abstract

Strontium sequestration by biomineralization of (Ba,Sr)SO₄ in desmid green algae is examined quantitatively with synchrotron X-ray fluorescence microscopy. An increase in Sr incorporation by more than two orders of magnitude in cells exposed to a modified culture medium may have implications for selective removal of ⁹⁰Sr from contaminated nuclear waste or the environment.
