Inactivation of luminous Vibrio spp. by free chlorine
In vitro inactivation of penaeid shrimp larval pathogens, Vibrio iiarveyi and Vsplendidus biovar 1, by free chlorine and the influence of organic matter on thebactericidal activity of chlorine were assessed. More than 5 log unit (>99.99%) reductionin luminous bacteria from >= log 6.00/ml within the first 60 sec of exposure to freechlorine at 1 ppm level was observed. Chlorine was ineffective at <50 ppm levels toinhibit luminous Vibrio spp in the presence of 0.1% peptone as interfering organic agent.These results revealed that luminous bacteria are highly susceptible to chlorine but thebactericidal activity of chlorine is affected by organic substance.
