Resumen:
Biodegradation of BPA had been
reported in waste water treatment plants, pure microbial cultures, and
nitrifying activated sludge. The objective of the present work was to analyze
the acclimation process of activated sludge to BPA in the absence and presence
of ammonium. Consecutive batch assays were performed in the presence and
absence of ammonium. Samples were taken at different times to determine
chemical oxygen demand (COD), total ammoniacal nitrogen (TAN), total phenols
(TP) and biomass (X) concentrations. Results suggest that the presence or
absence of ammonium did not modify the acclimation of the biomass or the
biodegradation of bisphenol A in the activated sludge system, and that the
acclimation of the biomass requires a minimum of three consecutive batch assays
