| Production of fumonisins B1 (FB1) and B2 (FB2) by two Brasilian strains (LAMIC 2999/96 and 113F) and one American strain (NRRL 13616) of Fusarium moniliforme were evaluated in laboratory cultures subjected to different temperatures (20, 25, and 30ºC), and moisture contents (25, 34, and 42%) on corn substrate. The cultures were grown during 10, 20, 30, 45, and 60 days, totalizing 135 treatments with two repetitions for each one. The fumonisins were extracted with acetonitrile/water. The clean-up with end-capped C18 silica (C18ec) cartridges and fumonisin derivatization with o-phtaldialdeyde were carried out through an automated sample processor system (ASPEC), followed by quantification of the toxins through HPLC. Fumonisin production varied widely,... |
