Abstract

Multi-parameter flow cytometric techniques have been used to study the effects of three ceramic powders CaO, MgO and ZnO on the physiology of individual, exponentially growing E. coli cells. Whilst all three powders inhibited reproductive growth, depending on their concentration, the mechanism of action of CaO and MgO was different to that of ZnO as shown by fluorescent staining techniques developed in our laboratory.
