Abstract
Toxinogenic Fusarium species were identified on grape berries from Slovak vineyards, and their toxic metabolites were analysed by HPLC-MS/MS. F. subglutinans, F. oxysporum, F. proliferatum, F. semitectum, F. solani, F. subglutinans, and F. verticillioides were found with varying frequency. F. oxysporum and F. proliferatum, cultured in vitro on Czapek yeast autolysate agar and yeast extract sucrose agar, produced beauvericin, in the range from 3,265 to 13,400 μg/kg, and fusaproliferin in high concentration, ranging from 49,850 to 259,500 μg/kg. A maximum value of 2.24 μg/kg has been observed for beauvericin in dried grape berries. Fumonisin B1, and fumonisin B2 were also identified, and the observed levels ranged from 500 to 2,040 μg/kg. Over 2 years (namely 2008 and 2009) many other metabolites have been identified and analysed in grape berries, in particular: avenacein Y, apicidin, aurofusarin, chlamydosporol, 2-amino-14,16-dimethyloctadecan-3-ol, enniatin A, enniatin A1, enniatin B2, enniatin B3, and equisetin.
