Fumonisin B1-4-producing capacity of Hungarian Fusarium verticillioides isolates.

摘要: The fumonisin B1-4 (FB1-4) toxin-producing capacities of 60 strains Fusarium verticillioides isolated in the main maize-cultivating areas Hungary were screened on rice grains vitro. amounts FB1, FB2, FB3 and FB4 extracts culture material determined by RP-HPLC/ESI-IT MS without any sample clean-up. All F. produced all analogues B series. did not differ significantly their cultural characteristics, though analytical results allowed distinction three idiosyncratic FB1-4-producing chemotypes with characteristic proportions analogues. dominant chemotype them sequence FB1 > FB2 FB4, large FB2. A second a higher amount than while third FB4. proportion was inversely correlated total FB yield. No differences FB1-4 pro...
