Growth response of Pseudomonas stutzeri RS34 to ethylenediaminetetraacetic acid (EDTA) and its interaction with zinc.
Pseudomonas stutzeri RS34 is a less sensitive member of pseudomonads to toxic effect of EDTA, the effect of EDTA is more bacteristatic than bactericidal, and can be reversed by divalent cations. Zn2+ provides more specific protection than Mg2+. EDTA-treated cells show higher sensitivity to lysozyme confirming the chelating mode of action of EDTA that leads to destabilization of the outer membrane. Such metal resistant bacteria can be profitably employed in the removal of metals from polluted ecosystems.
