(a-b) Level of stress markers (a) MDA content; (b) H2O2 content in M. incognita inoculated 60 days old tomato plants treated with bioactive components produced by S. hydrogenans strain DH-16. Different treatments are represented as C (control), NI (nematode inoculated), CC (culture cells), CC + NI (culture cells + nematode inoculated), S (supernatant), S + NI (supernatant + nematode inoculated), E (crude extract), E + NI (crude extract + nematode inoculated). Results are given in mean ± standard error form and F-value ** indicates significance at p ≤ 0.01 as per Tukey’s test. Different letters a, b, c, d represent significant difference among treatments and same letters represent no significant difference.
