The effect of water availability (water activity (aw): 0.995-0.90) and temperature (18-30° C) on in vitro interactions between an ochratoxin producing strain of Aspergillus ochraceus and six other spoilage fungi was assessed in dual culture experiments on a maize meal based agar medium. Overall, Under all conditions tested, the Index of dominance for A. ochrceus was much higher than for other competing species combined suggesting that A. ochraceus is a good competitive colonist able to replace a number of other species. However, the growth rate of A. ochraceus was modified and decreased by the interaction with competitors. Interaction between A. ochraceus and species such as Alternaria alternata and Eurotium species resulted in a significant stimulation of ochratoxin production.
