Enhanced sensitivity to the photodynamic effect of 3,4-benzpyrene in ethylenediaminetetraacetate-treated Escherichia coli.
Ethylenediaminetetraacetate treatment of Escherichia coli B enhanced cell sensitivity to the lethal effect of the photodynamic action of 3,4-benzpyrene. The alteration of the shape of the survival curve suggests that such photodynamic action may be modified by membrane barriers to the drug.
