Aspergillus flavus is a well-known ubiquitous fungus able to contaminate both in pre- and postharvest period different feed and food commodities. During their growth, these fungi can synthesise aflatoxins, secondary metabolites highly hazardous for animal and human health. The requirement of products with low impact on the environment and on human health, able to control aflatoxin production, has increased. In this work the effect of the basidiomycete Trametes versicolor on the aflatoxin production by A. flavus both in vitro and in maize, was investigated. The goal was to propose an environmental loyal tool for a significant control of aflatoxin production, in order to obtain feedstuffs and feed with a high standard of quality and safety to enhance the wellbeing of dairy cows. The presence of T. versicolor, grown on sugar beet pulp, inhibited the production of aflatoxin B1 in maize by A. flavus. Furthermore, treatment of contaminated maize with culture filtrates of T. versicolor containing ligninolytic enzymes, showed a significant reduction of the content of aflatoxin B1.
黄曲霉是一种广为人知的常见真菌，在收获前和收获后的不同时期都能污染各种饲料和食品。在其生长过程中，这些真菌能够合成黄曲霉毒素，这是对动物和人类健康危害极大的次生代谢产物。对环境和人类健康影响较小且能够控制黄曲霉毒素产生的产品的需求日益增加。在这项研究中，研究了担子菌云芝对黄曲霉在体外和玉米中产生黄曲霉毒素的影响。目的是提出一种对环境友好的工具，以有效控制黄曲霉毒素的产生，从而获得高质量和安全标准的饲料和饲粮，以提高奶牛的健康水平。生长在甜菜粕上的云芝的存在抑制了黄曲霉在玉米中产生黄曲霉毒素B1。此外，用含有木质素分解酶的云芝培养滤液处理受污染的玉米，结果表明黄曲霉毒素B1的含量显著降低。
