Relative tolerance of Escherichia coli strains to Cd 2+ is induced by prior growth in medium containing low levels of either Cd 2+ or Hg 2+ , and maximal induction appears to be dependent upon recA + function. Biosynthesis of glutathione is not required for induction or for expression of induced resistance. Salmonella typhimurium strains are relatively resistant to Cd 2+ , and this resistance is essentially constitutive.
