摘要：The strain Pseudomonas aeruginosa NR.22 (Ps.NR.22); an extracellular laccase producer isolated from a polluted lake in Malaysia has been proved to grow very well in 1000mg/L Bisphenol A (BPA). Therefore, the kinetics of BPA utilization and bacterial growth is investigated to determine the possibility of using Ps.NR.22 as an alternative method in the bisphenol A (BPA) removal from aqueous solution and contaminated open water bodies. This study has been modelled using a shake flask system with the ability of the strain to remove about 90% of BPA; recorded after 72 hours of incubation. The kinetic parameters are verified to improve the biological removal of BPA from the environment. Effect of various parameters such as contact time, pH, temperatures, initial BPA concentrations and cell dosages has been carried out in this study. The optimum conditions for the removal of BPA within the experiment range of variables studies were 250mg/L of initial BPA concentration, 6x106 g/L of cells, pH value of 6.0 and 92 min of contact time. Under these conditions the maximum removal efficiency was 90.5% using 1000mg/L and 100% using 250mg/L BPA.
