All strains (92) of A. flavus group proved to be positive for production of aflatoxin (45 to 1200 micrograms/50 ml medium) on potato dextrose liquid medium, while 59 strains only proved to be positive (35-310 micrograms/50 ml) on 15% NaCl potato-dextrose liquid medium. Most of the strains tested of A. flavus, A. flavus var. columnaris and A. oryzae produced aflatoxins B1, B2, G1 & G2. All positive strains of A. tamarii produced aflatoxins G1 & G2 while the tested isolate of A. zonatus produced aflatoxins B1 & G1. Of 95 strains tested of Eurotium, aflatoxins B1 & G1 were produced by one strain of each of E. chevalieri var. intermedium, E. repens and E. rubrum. Gliotoxin was detected in the extract of two strains of E. chevalieri and one strain of each of E. chevalieri var. intermedium and E. pseudoglaucum on the salt-free medium, and two strains of each of E. chevalieri, E. chevalieri var. intermedium and one of E. pseudoglaucum on 15% NaCl medium. Sterigmatocystin was produced by some strains of E. chevalieri, E. chevalieri var. intermedium, E. amstelodami, E. pseudoglaucum and E. rubrum on the two experimental media. One strain only of E. repens produced ochratoxin A while citrinin was detected in the extract of one strain of E. pseudoglaucum.
在马铃薯葡萄糖液体培养基上，黄曲霉群的所有菌株（92株）均被证明能产生黄曲霉毒素（45至1200微克/50毫升培养基），而在15%氯化钠马铃薯葡萄糖液体培养基上，只有59株被证明呈阳性（35 - 310微克/50毫升）。大多数测试的黄曲霉、柱形黄曲霉变种和米曲霉菌株产生了黄曲霉毒素B1、B2、G1和G2。所有阳性的寄生曲霉菌株产生了黄曲霉毒素G1和G2，而测试的棕曲霉分离株产生了黄曲霉毒素B1和G1。在测试的95株曲霉菌株中，谢瓦利埃曲霉变种中间型、蔓延曲霉和红曲霉各有一株产生了黄曲霉毒素B1和G1。在无盐培养基上，在两株谢瓦利埃曲霉以及中间型谢瓦利埃曲霉变种和拟灰绿曲霉各一株的提取物中检测到了胶霉毒素；在15%氯化钠培养基上，谢瓦利埃曲霉、中间型谢瓦利埃曲霉变种各有两株以及拟灰绿曲霉有一株检测到了胶霉毒素。一些谢瓦利埃曲霉、中间型谢瓦利埃曲霉变种、阿姆斯特丹曲霉、拟灰绿曲霉和红曲霉的菌株在两种实验培养基上产生了柄曲霉素。只有一株蔓延曲霉产生了赭曲霉毒素A，而在一株拟灰绿曲霉的提取物中检测到了桔霉素。
