摘要：

Peanut meal, as an important feed and protein source, is highly susceptible to aflatoxin contamination. Probiotics with the advantages of aiding digestion and improving intestinal function are regarded as potential ways to detoxify aflatoxins. In this study, six probiotic strains screened from peanut meal were identified and used for aflatoxin detoxification. The strain of Bacillus velezensis NWPZ-8 noted as A43 showed the best ability to detoxify aflatoxins. The optimized aflatoxin B-1 detoxification conditions by A43 in peanut meal were proposed. At these conditions, the strain not only detoxified 75.29% aflatoxin B1 but also increased the content of protein and amino acids in peanut meal. It was found that the aflatoxins detoxification activity by A43 was mainly attributed to the extracellular proteins. Therefore, this study provides a potential probiotics strain that can be used for aflatoxin detoxification in peanut meal.
