Abstract:Summary Growth of Tetrahymena pyriformis (Gl) was studied in axenic culture in the presence of cadmium. The maximum growth rate is not affected by concentrations of cadmium below 1.5 mg/l (1.3×10–5 M). The concentration reducing the growth rate to 50% of its initial value is 2.6 mg/l (2.3×10–5 M) and the lethal dose is 5 mg/l (4.5×10–5 M).The mean cell volume, mean cell dry weight, mean cell protein content, yield and respiration rate were compared at 0, 0.2 and 2.0 mg/l Cd. No significant differences were detected for these parameters between control and treated groups.
