Description

Molds are multicellular microorganisms that are commonly found in soil and some rotten plants in the form of spores. The fungal spores in the soil spread through the air, water and insects to plants. Once the spores come into contact with the broken seeds and spore germinate quickly, the mildew can be seen clearly. Mycotoxins are mainly produced by four species of fungi, Aspergillus, Penicillium, ergoconion and Fusarium. Aspergillus is mainly secreted by aflatoxin and ochratoxin, and the genus Penicillium mainly secretes citrinin, and ergobacteria mainly secretes ergotoxin, and Fusarium genera mainly secretes vomit toxin, corn chearalenone, T*2 toxin and so on. The mycotoxin in feed mainly comes from the mold contamination and reproduction in the process of raw material, processing and storage, including aflatoxin, ochratoxin, zearalenone, vomicenin, T*2 toxin, citrinin, and ergotoxin. So far, more than **0 mycotoxins have been isolated and identified, and the above toxins are widely recognized toxins. Mycotoxins are produced in the process of grain production, feed production, storage and transportation. Because of the massive presence of mycotoxin producing fungi and the uncontrollable conditions for the growth and reproduction of most fungi and the production of mycotoxins, the problem of contamination of food and feed by mycotoxin has become a difficult problem in modern agricultural production, which has caused great importance to grain producers, livestock breeders, and food and feed processing enterprises.
