The numbers of survivors of a culture of Staphylococcus aureus were the same after storage at a relative humidity of 43% as at 100%; drying did not appear to affect the sensitivity of Staph. Quaternary ammonium compounds (quats), such as benzalkonium chloride (see Fig. 1.34 for the chemical structure), are a large group of related compounds. Unlike the ammonium ion and the primary, secondary, or tertiary ammonium cations, the quaternary ammonium cations are permanently charged, independent of the pH of their solution. (C) In isothermal process, Wreversible = - nRT InV.AH Thus, QACs damage the outer layers of bacteria [9], thereby promoting the release of intracellular constituents.
