Abstract

Zearalenone was detected as the natural contaminant in two samples of Amaranthus cruentus grains (1980 micrograms/kg and 420 micrograms/kg, respectively). Fungi isolated from these samples were screened for mycotoxin production. Two of eight isolates of Fusarium (F. equiseti and F. moniliforme) produced zearalenone. One of four isolates of Aspergillus flavus and all four isolates of A. parasiticus produced aflatoxins. Other species potentially toxicogenic such as Aspergillus versicolor, Penicillium viridicatum, P. puberulum, P. crustosum, P. citrinum, P. expansum and Fusarium solani were also found.

摘要

在两个籽粒苋籽粒样本中检测到玉米赤霉烯酮这种天然污染物（分别为1980微克/千克和420微克/千克）。对从这些样本中分离出的真菌进行了霉菌毒素产生情况的筛查。八株镰刀菌分离株中有两株（木贼镰刀菌和串珠镰刀菌）产生了玉米赤霉烯酮。四株黄曲霉分离株中的一株以及所有四株寄生曲霉分离株产生了黄曲霉毒素。还发现了其他具有潜在毒性的物种，如杂色曲霉、绿青霉、短柄青霉、皮落青霉、桔青霉、扩展青霉和茄病镰刀菌。
