The formation of biofilm was closely monitored for a period of 522 days by total bacterial counts (AODC), heterotrophic plate counts (R2A media), and ATP content determinations. The biofilm grew at a rate of 0.030±0.002 day−1 reaching quasi-stationary state at 2.6×106 cells/cm2 after approximately 200 days. The low substrate level in the bulk phase (AOC at approximately 6 µg ac-C/l) most likely caused the relatively slow biofilm formation rate observed. During the maturation of the biofilm, the bacterial community changed properties in terms of cell-specific ATP content and culturability of the bacteria. biofilm, drinking water, formation, growth, stationary phase This content is only available as a PDF. © IWA Publishing 2002 You do not currently have access to this content.
