Tolerance of Escherichia coli to Cadmium
1973
Zwarun, A. A.
The effect of Cd on Escherichia coli was studied by measuring the quantity of ¹⁴CO₂ produced from ¹⁴C-glucose by the organism in the presence of increasing amounts of Cd. The test medium was a simulated fresh-water source consisting of 0.01% soy peptone in sterile, deionized water (pH 6). Decimal dilutions of Cd, as CdCl₂, had no effect on the ability of the organism to produce ¹⁴CO₂ in concentrations ranging from 0.006 µg Cd/liter to 0.6 mg Cd/liter. At 6 mg Cd/liter a decrease in ¹⁴CO₂ production was noticed, and a higher concentration of Cd reduced ¹⁴CO₂ evolution even further. The decrease in ¹⁴CO₂ evolution by E. coli could be correlated with a decrease in the number of cells surviving the Cd treatments.
