Kinetic aspects of biofilm formation on surfaces exposed to drinking water

摘要: Biofilm formation in drinking water distribution systems should be limited to prevent the multiplication of undesirable bacteria and other organisms. Certain types with an AOC concentration below 10 μg acetate-C eq/l can support growth Aeromonas . Therefore, effect acetate at a C/l on biofilm rate (BFR) low (3.2 C/l) was determined. Drinking without had BFR 3.9 pg ATP/cm 2 .day, whereas value 362 .day found added. These data indicate that strongly affects formation, only small fraction is available for formation. Aeromonads did not multiply despite their ability grow acetate-C/l. Further investigations are needed elucidate relationship between substrate these biofilms.
