Abstract
One hundred and forty-eight isolates of Aspergillus flavus and A. parasiticus were isolated from 5,608 pecans obtained from Chicago and Georgia markets. The percentage of internal contamination by these species was 7.3% in the Chicago market pecans and 1.7% in those from markets in Georgia. Of the 148 isolates, 93% of the A. parasiticus, but only 54% of the A. flavus, were capable of producing aflatoxin. Overall, 57% of the isolates were potentially aflatoxigenic. A. parasiticus isolates generally produced a greater amount of aflatoxins than A. flavus.
摘要
从芝加哥和佐治亚州市场采购的5608颗山核桃中分离出148株黄曲霉和寄生曲霉。这些菌种在芝加哥市场山核桃中的内部污染率为7.3%，在佐治亚州市场山核桃中的污染率为1.7%。在这148株分离菌中，93%的寄生曲霉能够产生黄曲霉毒素，而黄曲霉只有54%能产生。总体而言，57%的分离菌具有潜在产黄曲霉毒素能力。寄生曲霉分离菌通常比黄曲霉产生更多的黄曲霉毒素。
