Growth curve analysis of Aspergillus flavus isolates AF13 and NRRL3357 under increasing oxidative stress and conidial concentration. The growth of AF13 (a, c) and NRRL3357 (b, d) were examined under increasing H2O2 concentrations in YES medium inoculated with either 2.0 × 104 (a, b) or 8.0 × 104 conidia/mL (c, d) by monitoring absorbance at 405 nm over 100 h. A threshold of 0.2 was selected for growth initiation timing which corresponded with linear phase initiation for both isolates in most conditions and is indicated by the dashed red line. Error bars represent standard deviation. No growth was detected at H2O2 concentrations > 15 mM in NRRL3357 with earlier growth initiation detected at higher conidia concentrations
