Abstract
Mucoid strains of Pseudomonas aeruginosa are characterized by an overproduc tion of the extracellular polysaccharide alginate. When suspended into chlo rinated swimming-pool water or drinking water samples, mucoid bacteria reve aled enhanced survival compared with isogenic nonmucoid cells. Removal of s lime from mucoid bacteria abolished chlorine resistance, addition of purifi ed alginate to washed bacteria again enhanced survival. Thus, alginate-cont aining slime confers protection on P. aeruginosa against chlorine and may c ontribute to survival of these bacteria in chlorinated water systems.
