Abstract:
The natural occurrence of fungal contamination was
evaluated in stored maize in three different agro-ecological zones (Iran,
Brazil and China). A total of 45 samples were analyzed and 685 fungal
isolates were identified. The most frequent isolated fungi from maize
originated from Iran, Brazil and China were Fusarium sp. (17.3,
17.9 and 37.1%), Aspergillus sp. (9.3, 17.4 and 19.7%), Penicillium
sp. (5.8, 15.2 and 17.6%), Rhizopus sp. (2.4, 3.2 and 3.5%),
Mucor sp. (1.1, 1.6 and 1.3%), Cladosporium sp. (1.6, 1.9
and 1.9%), Alternaria sp. (1.1, 1.6 and 1.3%), Geotrichum sp.
(0, 0 and 0.3%), Acromonium sp. (0.5, 0.8 and 0%) and Absidia
sp. (0, 0.8 and 0.5%), respectively. Significant difference was observed
between the frequency of fungal isolates of Iranian maize and foreign
products (p<0.0005). Maize mycoflora profiles showed that Fusarium
verticillioides and Aspergillus flavus prevailed in 30.7 and
13.3% of the samples from China, in 12 and 5.3% of the samples from Iran
and 11.7 and 11.5% of the samples from Brazil, respectively. There were
significant differences in the frequency of Fusarium verticillioides
in Chinese maize with other countries products (p<0.0005) and that
of Aspergillus flavus in Iranian maize with other countries (p<0.002).
The results emphasize that farmers and consumers should be alerted to
the danger of fungal contamination in maize.
