Effect of Transient Nicotine Load Shock on the Performance of Pseudomonas sp. HF-1 Bioaugmented Sequencing Batch Reactors

Figure 4

The oxidative stress in the reactors with different nicotine shock loads. Reactor R1 was the control without nicotine shock load; reactors R2 to R6 were with the nicotine shock load of 500, 1000, 1500, 2000, and 2500 mg/L, respectively. (a) ROS; (b) MDA; (c) SOD; and (d) CAT.
