Mycotoxins Biosynthesis by Fusarium Oxysporum and F. Proliferatum Isolates of Asparagus Origin

Mycotoxins Biosynthesis by [Fusarium Oxysporum] and [F. Proliferatum] Isolates of Asparagus Origin The subject of this work was fumonisin B[1] (FB[1]) and moniliformin (MON) biosynthesis by three isolates of [Fusarium oxysporum] and three isolates of [F. proliferatum] of asparagus spears origin. The cultures of fungi were grown on rice and asparagus media for 3 weeks at 20°C. Experiment was carried out in 3 replicates. FB[1] and MON occurrence was evaluated with high-performance liquid chromatography (HPLC) analyses. Analysis of variance was carried out to determine biosynthesis of FB[1] and MON by [F. oxysporum] and [F. proliferatum.] FB[1] was found in the amount up to 2012.8 μg/g in cultures of [F. proliferatum] on rice and in a very small amount in two cultures on asparagus medium. [F. oxysporum] did not produce FB[1] on any of the media. MON was biosynthesized by two the same isolates of [F. oxysporum] in the amount up to 182.8 μg/g on rice and up to 743.3 μg/g on asparagus medium and one isolate (different on each medium) of [F. proliferatum.]
