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.
