Protection of cadmium toxicity to B. cereus, E. coli and A. niger by Na+, Mg++ and Ca++ ions.
10ppm of cadmium apparently seem to extend the lag phase of Bacillus cereus and Escherichia coli but in reality both 10 and 100ppm decreased the growth with differing intensity. 1.0ppm of cadmium decreased the growth of Aspergillus niger, and it failed to grow at 500ppm. However, addition of calcium, magnesium and sodium gave increasing protection against cadmium toxicity for the growth of B. cereus, E. coli an A. niger. It is inferred that environment pollution by cadmium is related to the cationic availability in the environment.
