Crosstalk between Mycotoxins and Intestinal Microbiota and the Alleviation Approach via Microorganisms

Toxins, 2022
Mycotoxins are secondary metabolites produced by fungus. Due to their widespread distribution, difficulty in removal, and complicated subsequent harmful by-products, mycotoxins pose a threat to the health of humans and animals worldwide.
