Abstract

The natural occurrence of major Alternaria mycotoxins i.e. alternariol (AOH), alternariol methyl ether (AME), altenuene (ALT), altertoxin-1 (ATX-1) and tenuazonic acid (TA) has been investigated in sorghum (Sorghum vulgare Pers.) and ragi (Eleusine coracana Gaertn.) collected from North Bihar. Nine out of 20 sorghum samples, and three out of eight ragi samples, were found to be contaminated with one to three Alternaria mycotoxins. The toxin elaborating potential of Alternaria alternata (Fr.) Keissler strains isolated from sorghum and ragi have also been investigated. Out of 16 isolates of A. alternata (Fr.) Keissler, mycotoxins were detected in only 10.

摘要

对从比哈尔邦北部采集的高粱（Sorghum vulgare Pers.）和龙爪稷（Eleusine coracana Gaertn.）中主要链格孢霉菌毒素即交链孢酚（AOH）、交链孢酚单甲醚（AME）、细交链孢菌酮酸（ALT）、互隔交链孢酚毒素-1（ATX-1）和细交链格孢菌酮酸（TA）的自然存在情况进行了调查。在20个高粱样品中有9个，8个龙爪稷样品中有3个被发现受到一至三种链格孢霉菌毒素的污染。还对从高粱和龙爪稷中分离出的链格孢（Alternaria alternata (Fr.) Keissler）菌株产生毒素的潜力进行了研究。在16株链格孢（Alternaria alternata (Fr.) Keissler）分离物中，仅在10株中检测到了霉菌毒素。
