Aspergillus parasiticus RCMB 002001 (2) producing four types of aflatoxins B₁ B₂, G₁, and G₂ was used in this study as an aflatoxin-producer. Penicillium griseofulvum, P. urticae, Paecilomyces lilacinus, Trichoderma viride, Candida utilis, Saccharomyces cerevisiae as well as a non-toxigenic strain of Aspergillus flavus were found to be able to exhibit growth on aflatoxin B₁-containing medium up to a concentration of 500 ppb. It was also found that several fungal strains exhibited the growth in co-culture with A. parasiticus, natural aflatoxins producer, and were able to decreased the total aflatoxin concentration, resulting in the highest inhibition percentage of 67.2% by T. viride, followed by P. lilacinus, P. griseofulvum, S. cerevisiae, C. utilis, P. urticae, Rhizopus nigricans and Mucor rouxii with total aflatoxin inhibition percentage of 53.9, 52.4, 52, 51.7,44, 38.2 and 35.4%, respectively. The separation of bioremediation products using GC/MS revealed that the toxins were degraded into furan moieties.
