Figure 9. Heavy metal accumulation of wild-type (DY1455) and TcOPT3-transformed yeast cells.

Zn, Fe, Ni, Cd and Cu accumulation in yeast transformants. Metal accumulation was conducted in liquid SD media supplemented with 50 µM FeCl₃, 50 µM ZnSO₄, 20 µM CdCl₂, or 50 µM CuSO₄ respectively. Data are the means ± SE per experiment (n = 3), P<0.05 by Student’s t-test.
