A comparative study of mycoflora of Iranian and imported soybeans

The natural occurrence of fungal contamination was evaluated in stored soybeans in different agro-ecological zones. Of 30 samples examined, fungal contaminations were positive in 25.9 percent and 74.1 percent of Iranian and imported soybeans (p<0.05). The total fungal CFU/g counts were calculated 6.3 * 102 in Iranian and 18 * 102 in imported samples. The most frequent isolated fungi from soybeans originated from Iran and imported were Aspergillus spp. (59.7, 58.6 percent), Penicillium spp. (26.8, 27.3 percent), and Fusarium spp. (13.5, 14 percent), respectively. Soybeans with a high incidence of diverse species of fungi to need for proper surveillance and monitoring for the prevention of fungal and mycotoxin contaminations.
