| Abstract: | Spores ofFusarium sacchari var.subglutinans isolated from broiler feed BR1 were obtained at an average concentration of 1.5/mg in 25% of tested samples. The spore concentration was increased from 1 to 100/mg of solid substrate (BR2; biscuit) or to 1/nL of Sabouraud broth after 3 weeks of cultivation. Mycotoxin analyses of these three substrates showed negative reactions for T-2 toxin and zearalenone but a positive reaction for deoxynivalenol (DON) which was found in concentrations of 5 ppm in Sabouraud broth, 50 ppm in BR2 and 220 ppm in biscuit. Therefore, ourF. sacchari isolate appeared to be a DON producer. |
