Fumonisin production on irradiated corn kernels: effect of inoculum size.

Production of fumonisins by Fusarium moniliforme was evaluate on irradiated corn kernels inoculated with different spor concentrations (10-106) and incubated at 25 C and a water activity of 0.97.  There was a direct relationship between the level of toxin produced and inoculum size.  The highest levels of total fumonisin proiduced after 35 days of incubation were 5.028 and 9.063 mg/kg at 105 and 106 spores per ml, respectively.  The pattern of fumonisin production (FB1 > FB2 >FB3) in cultures growing fromdifferent inocula was not affected during the 35 days of incubation.  The ratio between FB2 and FB1  varied from 0.15 to 0.45 whereas the ratio between FB3 and FB1 varied from 0.34  to 0.87.
