The hydrophobicity of a wild-type strain (DC0) ofEscherichia coli and its envelope mutant (DC2) has been studied in different organic solvent systems. The surface of the mutant was considerably more hydrophobic when xylene,n-hexadecane,n-octanol, cyclohexane, and isopropy myristate were tested. Emulsion formation occurred with DC2, which could be cleared by adding 5% vol/vol isopropanol. Pretreatment of cell suspensions of CD0 and DC2 with chlorhexidine diacetate or benzalkonium chloride, followed by exposure to one hydrocarbon (xylene) test system, produced further changes in the hydrophobic nature of both strains. Following cellular treatment with chlorhexidine or benzalkonium, the surface of DC0 was changed from slightly to markedly hydrophobic. |
