Popis:	The interaction of EHEC with CTAC and CTAB in aqueous solution is investigated as a function of temperature, electrical conductivity, chloride ion self-diffusion (CTAC), and time-resolved fluorescence quenching (CTAC, CTAB). The EHEC-cationic surfactant strength increases with temperature, resulting in a decreased critical micellization concentration, increased micelle ionization degree, and decreased micelle aggregation number that can be used to explain the reaction with pyrene. The polymer-bound surfactant micelles may hinder the motion of probe and quencher more than free micelles. 36 refs., 5 figs., 1 tab.
