A Bench-Scale Procedure for Evaluating Chlorine Bleach Inactivation of Bacillus Spores in Wash Water from a Cleanup of a Site with Biothreat Agents
(PUBLISHED REPORT) [Published : May 02, 2019]
(PUBLISHED REPORT) [Published : May 02, 2019]
This report describes a streamlined bench scale procedure which has been developed for testing the efficacy of chlorine bleach for the inactivation of Bacillus spores in wash water originating from a cleanup of a site contaminated with Bacillus anthracis spores.
Chlorine and monochloramine disinfection of Legionella pneumophila colonizing copper and PVC drinking water biofilms
(JOURNAL) [Published : Jan 25, 2019]
(JOURNAL) [Published : Jan 25, 2019]
Building water systems (BWSs) promote the regrowth and survival of opportunistic pathogens, such as Legionella pneumophila, especially within biofilms (BFs), where most drinking water (DW) microbes reside. However, compared to their planktonic (PL) form, disinfection efficacy fo...
