Abstract
To determine the mode of action of free chlorine in inactivating coliforms, acid-fast bacteria and yeasts, the uptake of radioactive chlorine was determined. Cell-associated chlorine could be modeled by the Freundlich relationship, with either free available chlorine or hypochlorous acid as an independent variable.
Candida parapsilosis and
Mycobacterum fortuitum exhibited greater uptake of chlorine at pH 7.0 than at pH 9.14; an opposite effect of pH on uptake was noted with
Escherichia coli and may be ascribed to losses in cellular material. This study confirmed that cell-associated chlorine is responsible for the inactivation of vegetative microorganisms by free available chlorine.
