Abstract:
The effects of culture time on production and activity of Cercospora zeae-maydis toxins have been studied in this article. The mensuration of inhibition of radicle growth was used to examine the activity of the toxins. The results showed that the maximum production and the strongest inhibitory activity of Cercospora zeae-maydis toxins were obtained when it was statically cultured in the Fries nutrient fluid for 15ds. The maximum production of the toxins is 38.477mg/mL. The median inhibitory concentration on maize radicle growth of the toxins is 18.012%. This indicated that the statically cultured in the Fries nutrient fluid for 15ds was the most fitting formation conditions of Cercospora zeae-maydis toxins. The results of this study will provide the foundation for optimization of formation conditions of Cercospora zeae-maydis toxins.
