FIGURE 5.

The antioxidant metabolites of four salt-tolerant bacterial isolates (ST1, ST2, ST3, and ST4) in terms of (A) flavonoids, (B) polyphenols, (C) reduced GSH, (D) oxidized GSH (GSSG), and (E) total GSH per gram of bacterial cell weight 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.
