Using layers of irradiated but still fertile maize grain, the effects of water activity (0.995, 0.95 a(w)) and temperature (18, 30 degrees C) on interspecific interactions between Aspergillus ochraceus and five other spoilage fungi were examined. Asp. ochraceus was not competitive against Asp. flavus, Asp. niger, or Alternaria alternata at 18 degrees C when water was freely available (0.995 a(w)), while at 0.95 a(w) it was dominant against Asp. candidus, Asp. flavus and Alt. alternata. At 30… CONTINUE READING
