Resting cells of strain Idd2 exhibited high maximum Hg2+ removal capacity (59mg mercury per g dry cell weight [gdw−1]) by adsorption than those of resting cells of strain Idd1 (32mg gdw−1). The resting cells of strain Idd2 exhibited a higher Hg2+ desorption capacity using CaCl2 (68%) and EDTA (48%) than strain Idd1, depicting weaker binding of Hg2+ onto strain Idd2 unlike strain Idd1. The actively growing yeast cells showed opposite Hg removal characteristics to those of the resting cells. Strain Idd1 adsorbed less Hg2+ from culture medium supplemented with Hg2+ than strain Idd2. However, the growing strain Idd1 reduced and vaporized 27% of supplemented Hg2+ as metallic mercury (Hg0), while the growing strains Idd2 vaporized 15% of the supplemented Hg2+. These two yeast strains are potential biotechnological tools for the eventual bioremediation of polluted aquatic systems.
