LITERATURE

reaction activity in the presence of recombinant BPO-A1 peaks at 60°C whereas peak in the non-enzymatic activity of H2O2 is not observed in temperature range of 10-70°C. The increase in the activity of the enzyme with propanoic acid around 10-50°C is due to the peroxidation step because high activity in the nonenzymatic oxidative bromination step is maintained at low temperature, which suppresses the decomposition of the active species generated by the reaction between peracid and Br-. The active species is heat-labile. The significant decrease in activity around 65-70°C is attributed to decomposition of the active species
