Aflatoxin determination and identification of fungal microbiota in recently harvested corn (Zea mays L.).

 

The moisture content, the presence of aflatoxins and fungal microbiota were determined in 10 varieties of recently harvested maize. The highest moisture content obtained was 14% equalling 0.76 water activity. The total counts of fungi and yeasts were high, with significant infection by Fusarium (100%), followed by Penicillium (60%) and Aspergillus (35%). Among the 20 Aspergillus isolates, 35% belong to A. fumigatus, 30% to A. flavus, 30% to A. niger and 5% to A. ochraceus. The presence of aflatoxins was not found. The toxinogenic potential of 6 strains of A. flavus was estimated, and 3 strains were able to produce aflatoxin B1.
