Effect of indigenous mycobiota on ochratoxin A production by Aspergillus carbonarius isolated from soil: Ochratoxin in mixed cultures

This study determined the biotic interaction between 30 non-toxigenic indigenous strains of Aspergillus niger aggregate, Aspergillus flavus, Trichoderma spp., Mucor spp., Cladosporium spp., Ulocladium spp., Curvularia spp., Absidia spp., Geotrichum spp. and Acremonium spp., isolated from soil destin...

OTA production was completely inhibited when A. carbonarius was inoculated in a interactive mixed culture with all A. niger aggregate strains assayed, a 80 % of Trichoderma spp. strains, a 40 % of Cladosporium spp. strains, Acremonium spp and Geotrichum spp; only one strain of A. flavus tested was able to completely inhibit the mycotoxin accumulation.

These results demonstrated that OTA production by Aspergillua carbonarius strain was significantly influenced by the presence of different non-toxigenic fungal strains when growing together on paired cultures. © 2013 Society for Mycotoxin Research and Springer-Verlag Berlin Heidelberg.
