Detoxification of aflatoxin B1 by a spore coat protein through formation of the main metabolites AFQ1 and epi-AFQ1.

A variety of important agricultural crops host fungi from the genus can produce cancerogenic secondary metabolites such as aflatoxins. Consequently, novel strategies for detoxification and their removal from food and feed chains are required. Here, detoxification of Aflatoxin B1 (AFB1) by the multi-copper oxidase CotA (BsCotA) was investigated.
