Résumé : The authors recorded notable difference of sensitivity of Pseudomonas aeruginosa to chloroxylenol according to the growth medium; the amount of magnesium of the culture medium and the growth phase were not major factors. This difference, which can be extended to various strains, is due to a difference of permeability of the outer membrane. It is suggested that adsorption of medium components on the surface of the bacteria could participate in the phenomenon. Similar results were obtained with phenol and crystal violet. © 1986.
