中文摘要：从华北平原采集了44个自然干燥前后的玉米粒，并对真菌感染、霉菌毒素污染情况进行了评估。研究发现霉菌毒素的发生与相应产毒菌的发生率密切相关，本研究综合比较自然干燥前后玉米籽粒中霉菌感染和霉菌毒素污染尚属首次。
外文摘要：Forty-four pre- and post-nature drying maize kernels were collected from North China Plain and assessed for fungi infection and mycotoxins contamination. The percentage of fungi infection was significantly higher in pre-nature drying samples than post-nature drying samples except for Fusariuim graminearum, which increases from 6.06% to 24.09%. Fusarium, Aspergillus, Alternaria and Trichoderma were main genera. Fusarium verticillioides (24.77%) and F. graminearum (15.08%) were predominant species, followed by Aspergillus niger (7.51%) and Aspergillus flavus (4.93%). FB1 and DON were the major mycotoxins presented in the samples, followed by ZEN. All samples showed FB1 ranging from 16.5 to 315.9 μg/kg. All post-nature drying maize kernels showed DON ranging from 5.8 to 9843.3 μg/kg, while 7 of 22 pre-nature drying samples contaminated with DON ranging from 50.7 to 776.6 μg/kg. The samples contaminated with ZEN in pre- and post-nature drying maize were 3, with the content ranging from 60.5 to 147.6 μg/kg and from 40.7 to 1056.8 μg/kg, respectively. Only 1 sample contaminated with AFB1 of 148.4 μg/kg. The occurrence of mycotoxins is highly in accordance with the incidence of the corresponding mycotoxin-producing fungi. This is the first comprehensive comparison of fungi infection and mycotoxins contamination between pre- and post-nature drying maize kernels.
