Average ± and standard deviation, n = 3. Different capital letters show differences in sugar production when comparing endophytic bacteria in 0 M NaCl. Different lowercase letters show differences when comparing endophytic bacteria in 2.5 M NaCl. Asterisk (*) shows a significant difference when comparing the same bacteria in 0 or 2.5 M NaCl. In all cases, one-way ANOVA and Tukey´s post hoc test (α = 0.05) were used. Nd = not detected.
