Dysprosium Absorption of Aluminum Tolerant- and Absorbing-Yeast

Background: Biosorption plays important roles in the recovery of rare earth metals. The absorption of dysprosium (Dy) was tested in yeast. Interestingly, brewing yeast, <i>Saccharomyces cerevisiae</i>, showed Dy absorption, and two strains, Alt-OF2 and Alt-OF5—previously isolated as high...

description Background: Biosorption plays important roles in the recovery of rare earth metals. The absorption of dysprosium (Dy) was tested in yeast. Interestingly, brewing yeast, <i>Saccharomyces cerevisiae</i>, showed Dy absorption, and two strains, Alt-OF2 and Alt-OF5—previously isolated as highly aluminum-tolerant and -absorbing yeast strains—were screened and shown to be superior in terms of their Dy absorption when compared to <i>S. cerevisiae</i>. Here, we analyzed the Dy absorption in these yeast strains. Methods: Dy absorption in yeast strains was measured using an inductively coupled plasma optical emission spectrometer (ICP-OES). Dy concentration and localization in yeast cells and the effect of treated pH on the Dy absorption were assayed. Results: The Dy absorption of Alt-OF2 and Alt-OF5 was more than two times that of <i>S. cerevisiae</i>. The absorption of Dy took place inside of the cells, and a small amount was found in the cell wall fraction. Conclusion: These results suggest that yeast offers a promising solution to the biosorption of rare earth metals and that it is possible to use the highly absorbent strains to breed a yeast strain that can recover even higher concentrations of Dy.
