title: Efficacy of biocides on laboratory-generated Legionella biofilms.
abstract: Results of biocide efficacy testing on laboratory-generated microbial biofilms containing Legionella bozemanii is presented. These show that chlorine is effective at recommended concentrations in cooling towers; at least 48 h contact between free chlorine and the biofilm is necessary. Of five commercial biocides tested, those containing isothiazolinones and dibromonitrilo-proprionamide were most effective against sessile L. bozemanii.
