Production of 3-acetyldeoxynivalenol in shake culture
- 1 Downloads
In order to produce deoxynivalenol (DON), conditions for the production of 3-acetyldeoxynivalenol (Ac-DON) in shake culture were studied. A selected isolate of DON-producer,F. graminearum strain R2118, produced about 70mg/mL of Ac-DON when cultured at 25°C for 4 days in a medium consisting of 3% sucrose, 0.1% peptone, and 0.1% yeast extract. From the mass culture (10 L) of the strain, 792 mg of Ac-DON were isolated and 384 mg of DON were obtained after hydrolysis of the acetate.
