Mercury pretreatment selects an enhanced cadmium-accumulating phenotype in Euglena gracilis.

Abstract excerpt

Pre-treatment of heterotrophic cultures of Euglena gracilis with 1.5 microM HgCl(2) for at least 60 generations resulted in a cell population that showed both increased resistance to Cd(2+) and ability to accumulate it, when compared to non-Hg(2+)-pretreated Euglena. These Hg(2+)-enhanced capacities were evident in cells cultured in the dark in a medium with lactate, but not in cells cultured with glutamate plus...
