Fumonisin production ability of Fusarium species isolated from corn in Croatia and Slovak Republic

Fumonisin B1 and B2 are mycotoxins mainly produced by Fusarium moniliforme, one of the most prevalent contaminant to corn cultivation. A total of 25 Fusarium strains were isolated from 60 corn samples collected from Eastern part of Croatia during 1997 and 1998. Fusarium moniliforme were isolated in 40% of total number of strains. Other species included; F. sporotrichoides (8%), F. verticillioides (4%), F. oxysporum (16%), F. tricinctum (4%), F. graminearum (4%) and F. culmorum (4%). The ability of F. moniliforme strains and other Fusarium isolates, to produce fumonisins, was assessed in comparisn with 10 strains of F. moniliforme isolated from corn in Slovak Republic. Samples were analyzed by TLC procedure developed in our modification, with pure standard solutions of Fumonisin B1, on silica gel GF254 in mobile phase acetonitrile-toluene-water (95:5:3). All examinated strains of F. moniliforme produced FB1.
