Abstract
The production of nivalenol (NIV) and fusarenon-X (FX) by Fusarium sp. strain Fn 2 B on three cereal substrates (polished rice, wheat and corn) was examined. The highest productions of both NIV and FX were observed on polished rice. The maximal yields of NIV and FX on polished rice were 8, 532 mg/kg after 28 days at 25°C and 1, 992 mg/kg after 14 days at 25°C, respectively, and their amounts were markedly decreased at lower temperature.
