Effect of temperature on diacetoxyscirpenol production and on sporulation in a liquid culture of Fusarium sambucinum

: F. sambucinum grown for 14 days on peptone supplemented Czapek medium produced higher amount of diacetoxyscirpenol at + 15 degrees C than at + 25 degrees C or at temperature kept successively at + 15 degrees C (day) and + 5 degrees C (night). There was no correlation between the spores number and the toxin level, but toxin synthesis began only with sporification and then continued until the 14th day.
