The effect of co-existing mycoflora with Aspergillus flavus was observed on wheat grains for its influence on aflatoxin B1 and G1 production. All 17 types of associations of different fungal species inhibited aflatoxin B1 production at different levels (48.21–90.23%). Among the screened co-existing moulds, the minimum inhibition in aflatoxin B1 production was caused by A. japonicus and the maximum inhibition was caused by Penicillium citrinum (90.23% and Trichoderma viride (90.15%). However, aflatoxin G1 production was completely inhibited by Aspergillus fumigatus, A. niger, Candida albicans, Chaetomium globosum, Penicillium citrinum, Trichoderma viride and a toxigenic strain of Aspergillus flavus. These results suggest the potential of co-existing moulds in biological control against pre and post harvest aflatoxin contamination of agricultural commodities.
