Popis: Rare earth metal cations are antibacterially synergistic with anionic surfactants, yielding mixtures that have bactericidal activity against a variety of gram-positive and gram-negative bacteria at minimum concentrations ranging from 16 to 125 μg/ml. Uptake of surfactant byEscherichia coli increases in the presence of lanthanum, suggesting that the role of rare earth metal cations is to reduce the net negative surface charge on the bacteria, thereby increasing the affinity between the negatively charged surfactant and the bacterial surface.
