Abstract
Data indicate that chlorine can be used effectively as a sanitizing agent against enterococci. Exposure, in phosphate-buffered water suspensions, to 100 ppm available chlorine resulted in complete destruction in 0.25 min. An initial concentration of 10 ppm chlorine resulted in variable destruction of enterococci after 2 min; 5 ppm for 30 min never completely destroyed any of 50 enterococcus strains studied. Acidification of the chlorine solution is important for effective germicidal action. With a concentration of 10 ppm available chlorine at pH 5.8, no survival was noted after 2 min. With this concentration at pH 8.4, there was appreciable survival after 2 min.This publication has 0 references indexed in Scilit:
