FIGURE 6

The antioxidant enzyme activities that directly scavenge ROS of four salt-tolerant bacterial isolates (ST1, ST2, ST3, and ST4) including (A) CAT, (B) SOD, (C) GPX, and (D) POX under control and salinity stress conditions. Data are represented by the mean of at least three replicates, and error bars represent the standard error. Different small letters (a, b, c…) above bars indicate significant differences between means at p < 0.05.
