FIG 3.

TEM and EDX analyses of strain EG16 in the absence and presence of Cd. (a to d) TEM analyses. (a) Normal morphology of EG16 cells without accumulated Cd. (b and c) EG16 cells pretreated with 100 mg liter⁻¹ Cd²⁺. eds1 and eds2 indicate electron-dense granules in an EG16 cell. (d) EG16 cells pretreated with 200 mg liter⁻¹ Cd²⁺. Red arrows indicate cell regions with distorted morphologies and deformed cytoplasmic membranes. (e to g) EDX analyses of a cell without accumulated Cd (e), eds1 (f), and eds2 (g).
