Effect of cycling temperatures on the production of deoxynivalenol and zearalenone by Fusarium graminearum NRRL 5883.

The effects of three regimens of cycling incubation temperatures and incubation at constant 25° C on the growth of Fusarium graminearum and production of DON and ZEA on rice were compared.  The greatest fungal growth was found in cultures incubated at temperatures cycling between 15 and 30° C during a 6 week period.  The highest amounts of DON and ZEA were produced in cultures incubated at a constant 25° C for 2 weeks prior to incubation at a constant 15° C for an additional 4 weeks.  Under cycling incubation temperatures, maxiumum amounts of DON and ZEA were produced in cultures incubated at temperatures cycling between 15 and 30° C for 6 weeks.  Overall, there was no correlation between mould growth and production of either DON or ZEA.  However, DON production and ZEA production were correlated.
