Effect of UV Light and Sodium Hypochlorite on Formation and Destruction of Pseudomonas fluorescens Biofilm In Vitro

Pseudomonas fluorescens is one of the first colonizers bacterial biofilm in water systems and a member opportunistic premise plumbing pathogens (OPPPs). The aim this study was to examine effect UV light sodium hypochlorite on formation destruction mature P. ceramic tiles. Planktonic bacteria or were exposed (254 nm) for 5, 20 s. 0.4 mg/L 1 min. Mature also increased concentration 2 0.5, h combined with UV. Prolonged action an increase its combination gave best results inhibition after pre-treatment biofilm. hyperchlorination radiation shows better long exposure time, although even 120 min there no completely destroyed Furthermore, mechanism methods should be explored as well importance mechanical cleaning that crucial combating swimming pools.
