Water activity influence on the simultaneous production of DON, 3-ADON and 15-ADON by a strain of Fusarium graminearum ss of 15-ADON genotype

Water activity influence on the simultaneous production of DON, 3-ADON and 15-ADON by a strain of Fusarium graminearum ss of 15-ADON genotype

The influence of aw on DON and its acetyl derivatives biosynthesis by a strain of Fusarium graminearum s.s. (ITEM 4606) which produces DON, 3-ADON and 15-ADON was evaluated. Trichothecene production was studied on agar wheat 2% at 0.95 and 0.99 aw at different temperatures (10, 15, 20, 25 and 30 °C)...

Zusammenfassung:The influence of aw on DON and its acetyl derivatives biosynthesis by a strain of Fusarium graminearum s.s. (ITEM 4606) which produces DON, 3-ADON and 15-ADON was evaluated. Trichothecene production was studied on agar wheat 2% at 0.95 and 0.99 aw at different temperatures (10, 15, 20, 25 and 30 °C) and incubation times (7, 14, 21 and 28 days). Statistical analysis (ANOVA) showed that aw, temperature, incubation time and their interactions were significant on the production of DON, 3-ADON and 15-ADON (p
