Polyethoxyoctyl derivatives Triton X45 and Triton X100 induced leakage of cellular materials from Staphylococcus aureus . The total leakage of 260 nm‐absorbing material, potassium (K + ), amino acids and protein depended on the concentrations of surfactant, with K + loss occurring most rapidly. There appeared to be little quantitative correlation between loss of viability and leakage. It is suggested that leakage may reflect changes in membrane permeability resulting in the inability of cells to recover normal functions when placed in a growth‐supporting medium.
