Cu 2+ induced an efflux of potassium, inorganic phosphate, 260 nm‐absorbing materials and ribose‐containing molecules in Pseudomonas syringae . No detectable amounts of aspartic and glutamic acids leaked from the cells. It is proposed that the release of inorganic phosphate and other low molecular mass anionic metabolites probably played a role in re‐equilibrating the internal charge balance after the exit of K + ions.
