Abstract
The relationship between fungal growth and the production of fumonisin on maize grain by 25 strains of Fusarium moniliforme of different ori gins has been investigated. Although sporulation was essentially the s ame for all the strains (about 10(8) propagules g(-1) dry matter), erg osterol assays revealed marked variations in fungal biomass. All strai ns studied produced highly variable amounts of fumonisin B1, the highe st levels being observed in strains of ergosterol content above 400 mu g g(-1). However, no correlation could be established between the syn thesized biomass and the quantity of fumonisins produced. We verified that ergosterol is an indicator of mycelial growth, and therefore of t he potential toxicity of the analysed grain.
