| Abstract: | The antifungal activity of iturin A and its interaction with erythrocyte membranes were enhanced in the presence of surfactin. The modification of the properties of iturin A was explained by the formation of mixed iturin A-surfactin micelles. Such mixed micelles were easily generated when both lipopeptides were in aqueous solutions in the absence of mineral salts but the formation of these micelles did not occur when the solutions contained a high molarity of mineral cations. |
