This study was carried out to investigate the potential of  Pseudomonas aeruginosa  for the removal of bisphenol-A (BPA) from synthetic wastewater. To achieve this, BPA removal capability of  P. aeruginosa  with respect to BPA concentration, and temperature were examined in batch reactors. Experiments were conducted in the presence/absence of glucose, as a carbon source. The first set of experiments consisted of evaluating the kinetic of removal of BPA at different concentrations (5, 10, 20, and 30 mg BPA/L) without glucose. In the second set of experiments, three different glucose concentrations (0.5, 1.0, and 2.0 glucose/L) with BPA concentrations were tested. After settlement of the  P. aeruginosa  biomass in the shakers, supernatants and control groups were filtered and analyzed for BPA using high performance liquid chromatography. In the biotic study, BPA removal rates were between 63 % and 100 %. All concentrations of BPA under 20 mg/L were completely degraded at 25 and 35 ºC at first step. However, 30 mgBPA/L was decreased to 8.56 mg/L by  P. aeruginosa  at first step at 25 ºC. At the second step, all concentrations of BPA were completely degraded by the cells at the presence of glucose. Hence, it can be summarized that bisphenol A can be used by  P. aeruginosa  as an external carbon source in the wastewater environments.
