FIGURE 6.

Three bar graphs labeled A, B, and C compare absorbance at 600 nanometers for three strains (MC3 in red, SR2 in green, and K1III in purple) under different conditions: polyethylene glycol concentration, pH, and sodium chloride concentration. Error bars and statistical group letters are shown for each bar.

Abiotic stress-tolerance activities of potential isolates (A) Drought stress (PEG10% to 25%) (B) pH tolerance (5–9) (C) Salinity stress (NaCl 0.5% to 10%). Values are expressed as mean ± SD. Means with different lowercase letters in the same color bars differ significantly at p < 0.05, according to Tukey’s post hoc test.
