Figure 4.
The effect of carbon dioxide (400, 800, 1200 ppm) and aw (0.92, 0.95, 0.98 aw) on mycotoxin (deoxynivalenol and zearalenone) production (µg/kg) by acclimatised strain of F. graminearum cultivated on milled-maize agar for 21 days at 30 °C. DON and ZEA were not detected at 35 °C. Data are means of triplicates (n = 3) with bars indicating standard (SE). Different letters (small letters for DON, capital letters for ZEA) indicate significant difference (p < 0.05) by Tukey’s honestly significant difference (Tukey’s HSD); nd = not detected.
