- *Significant difference between untreated and treated cultures was demonstrated using the Student’s t-test (p < 0.05)

aChanges in dry cell mass (DCM) values were recorded 10 h after stress treatments. Mean ± S.D. values, calculated from 4 independent experiments are presented
-
bThe following stressor concentrations were employed in these experiments: MSB: 0.12 mM, low concentration (l)-H2O2: 5 mM, high concentration (h)-H2O2: 75 mM, tBOOH: 0.8 mM, diamide: 1.8 mM and NaCl: 0.6 M
