Abstract
The production of aflatoxins B1 and B2 by Aspergillus tamarii (subgenus Circumdati section Flavi) is reported for the first time. The fungus was isolated from soil collected from a tea (Camellia sinensis) field in Miyazaki Prefecture, Japan. Three single-spore cultures, NRRL 25517, NRRL 25518, and NRRL 25519, were derived from subcultures of the original isolate 19 (MZ2). Each of these single-spore cultures of A. tamarii produced aflatoxins B1 and B2 and cyclopiazonic acid, as well as black, pear-shaped sclerotia. The demonstration of aflatoxin production by A. tamarii is examined in connection with A. tamarii phylogenetic relationships, chemical ecology, and potential use in food fermentations.
摘要
首次报道了棕曲霉（曲霉属环带亚属黄曲霉组）产生黄曲霉毒素B1和B2。该真菌从日本宫崎县一个茶园（茶树）采集的土壤中分离得到。三个单孢培养物，NRRL 25517、NRRL 25518和NRRL 25519，源自原始分离物19（MZ2）的继代培养物。这些棕曲霉的单孢培养物均产生黄曲霉毒素B1和B2以及环匹阿尼酸，还产生黑色梨形菌核。结合棕曲霉的系统发育关系、化学生态学以及在食品发酵中的潜在用途，对棕曲霉产生黄曲霉毒素的情况进行了研究。
