A total of 260 isolates, including 43 species of Penicillium and 7 species of Aspergillus, were screened for their ability to produce aflatoxin on rice. Chloroform extracts were analyzed by thin-layer chromatography. None of the isolates produced aflatoxin. Certain species of Penicillium produced fluorescent substances that either were similar in R(F) or were of similar color to B and G aflatoxins. These substances were subsequently proved not to be aflatoxin by two-dimensional chromatography, by reaction with iodine fumes, or by both methods.
总共对260株分离菌株进行了筛选,其中包括43种青霉和7种曲霉,检测它们在大米上产生黄曲霉毒素的能力。用薄层色谱法分析氯仿提取物。没有分离菌株产生黄曲霉毒素。某些青霉物种产生的荧光物质,其比移值(R(F))与B型和G型黄曲霉毒素相似或颜色相近。随后通过二维色谱法、与碘蒸气反应或两种方法联用,证明这些物质并非黄曲霉毒素。
