Abstract
The nitrifying performance of the biofilm formed onto polymeric suppor ts (high density polystyrene, polyethylene, polypropylene, polyvinylch loride and polymethyl-methacrylate) was correlated with the hydrophobi city and surface charge of both bacteria and support media. Polypropyl ene, the most hydrophobic material, had the best properties for biofil m formation. The adhesion of nitrifying bacteria was mainly governed b y hydrophobic interactions though electrostatic interactions were a de terminant when the supports had identical hydrophobicity.
