From: Mercury removal during growth of mercury tolerant and self-aggregating Yarrowia spp.
TEM images and XEDS spectra of Hg deposits observed for Yarrowia sp Idd1. Cells after cultivation in absence of HgCl2 (a–c), cells grown in medium supplemented with HgCl2 showing cellular adsorption of Hg (d–f), extracted EPS of culture in medium without HgCl2 (g, h), and extracted EPS of culture in medium supplemented with HgCl2 showing Hg-EPS complex as Hg nanoparticles (i, j). Areas analysed with XEDS are indicated with dashed oval shapes for cells cultivated without HgCl2 (a, b), cells with HgCl2 (d, e), EPS of culture without HgCl2 (g), and EPS of culture with HgCl2 (i) along with their corresponding XEDS spectra obtained for cells without HgCl2 (c), cells with HgCl2 (f), EPS from culture without HgCl2 (h), and EPS from culture with HgCl2 (j) are shown
