The relationship between fungal growth and the production of fumonisin on maize grain by 25 strains of Fusarium moniliforme of different origins has been investigated. Although sporulation was essentially the same for all the strains (about 10(8) propagules g-1 dry matter), ergosterol assays revealed marked variations in fungal biomass. All strains studied produced highly variable amounts of fumonisin B1, the highest levels being observed in strains of ergosterol content above 400 micrograms g-1. However, no correlation could be established between the synthesized biomass and the quantity of fumonisins produced. We verified that ergosterol is an indicator of mycelial growth, and therefore of the potential toxicity of the analysed grain.
对25株不同来源的串珠镰刀菌在玉米籽粒上的真菌生长与伏马菌素产生之间的关系进行了研究。尽管所有菌株的孢子形成基本相同（约10⁸个繁殖体 g⁻¹干物质），但麦角固醇分析显示真菌生物量存在显著差异。所有研究菌株产生的伏马菌素B1量高度可变，在麦角固醇含量高于400微克 g⁻¹的菌株中观察到最高水平。然而，无法在合成生物量与产生的伏马菌素量之间建立相关性。我们证实麦角固醇是菌丝体生长的指标，因此也是所分析谷物潜在毒性的指标。
