Sensitization of E. coli to the Serum Bactericidal System and to Lysozyme by Ethyleneglycoltetraacetic Acid

Abstract

Summary

EGTA, but not Mg EGTA, was found to enhance the effects of the serum bactericidal system and of lysozyme on the survival of E. coli ATCC 25922. These observations are consistent with the hypothesis that Mg²⁺ is the critical divalent cation for maintaining the structural integrity of the E. coli cell wall.
