Compositions and methods for mycotoxin decontamination of animal feed, food, soil and plants using biomass of filamentous fungi and its selected components

A method of rendering harmless mycotoxins contaminating food, animal feed and assisting infection of plant hosts by microbial parasites is proposed. The method comprises binding mycotoxins by a novel adsorbent, consisting partially or in full of the biomass of filamentous fungi or isolated fungal biomass components, such as chitin, chitozan and hyrdophobins, or fungal biomass enriched in its capacity to bind said mycotoxins using fungal species and strain selection, genetic engineering of fungi, modification of fungal fermentation conditions and downstream physical and chemical treatment of fungal biomass, such as milling or micronization in a dry state. The resulting adsorbent can bind a wide range of mycotoxins, including the ones difficult to bind (Ochratoxin, T-2, DON, NIV) using a current generation of mycotoxin adsorbents based on clay, resins, yeast and bacterial biomass. The adsorbent can be used as an animal feed additive, functional food additive and agricultural fungistatic/fungicide.
