The effect of water activity (ax) temperature on the patterns of colonisation and fumonisin production in maize grain by isolates of Fusarium moniliforme and F.proliferatum in the presence of interacting spoilange fungi, such as Aspergillus flavus, A, niger A. ochraceus and Penicillium implicatum, was studied over 4 week incubation periods. At 0.93 and 0.95 ax, interactions of the two Fusarium species with other species to a large extent resulted in mutual inhibition on contact or overgrowth by the Aspergillus and Penicillium species, regardless of temperature and growth rates of the species. However, there was no decrese in fumonisin levels. Interaction with A.niger, A.ochraceus and A.flavus at 15 and 25oC and 0.98 aw resulted in a significant stimulation in fumonisin production by both Fusarium species. Interaction with P.implicatum resulted in a decrease in fumonisin production by F.moniliforme. However, interaction with F.proliferatum resulted in an enhanced production at both temperatures and 0.95 and 0.98 aw.
