Abstract

The production of mycotoxins by Alternaria alternata in cellulosic ceiling tiles was examined with thin-layer chromatography and high-performance liquid chromatography procedures. Alternariol and alternariol monomethyl ether were found in ceiling tile extracts, whereas extracts of control rice cultures of all three isolates produced these mycotoxins plus altenuene and altertoxin I. Extensive fungal growth and mycotoxin production occurred in the ceiling tiles at relative humidities of 84-89% and 97%.

摘要

通过薄层色谱法和高效液相色谱法检测了链格孢在纤维素天花板瓷砖中产生霉菌毒素的情况。在天花板瓷砖提取物中发现了交链孢酚和交链孢酚单甲醚，而所有三种分离株的对照水稻培养物提取物除了产生这些霉菌毒素外，还产生了细偶氮酸和互隔交链孢毒素I。在相对湿度为84 - 89%和97%时，天花板瓷砖中出现了大量真菌生长和霉菌毒素产生。
