The objective of this study was to investigate the effect of pH on the inactivation kinetics of
B. subtilis spores with combined chlorine in order to identify the operating conditions that
would enhance the inactivation efficiency of this residual disinfectant against the
pathogenic spores of B. anthracis. Materials and methods used and discussed in this paper include: preparation of spores; experimental matrix; disinfection procedures; and, viability assessment. Includes 8 references, figures.
