摘要
A new method is described for screening potential biocides based on the traditional suspension test using the Bioscreen optical plate reader, This nem method is rapid, reproducible, quantitative and cost effective. Data obtained by this new method are not directly equivalent to the log reduction normally quoted, but g-ive a measurement of the total effect of the biocide on the microbe population, measuring the effect of injury as well as death (non-viability), The method allows far the routine examination of disinfection kinetics, the study of which leads to greater scientific insight into disinfection than that achieved by the standard 5 min, one-point, disinfection tests currently employed.
