Abstract: | Fusarium sambucinum Fuckel var. minus isolate produced unusual for F. sambucinum Fuckel trichothecene metabolite 4,15-diacetylnivalenol (9 mg/l) in conditions of deep cultivation on Myro medium. This compound
was identified by TLC, GLC, HPLC, and 1H NMR spectroscopy. Other trichothecenes, 4-acetylnivalenol (3 mg/l) and nivalenol (1 mg/l), were also found in the culture.
The observed feature of the studied isolate is assumed to be due to the presence of an additional gene, which encodes cytochrome
P450 oxygenase responsible for the introduction of keto group at C-8 and hydroxyl group at C-7 of the trichothecene structure. |
