摘要:
Mycotoxins prevailing in Northern climates have been until now proven difficult to deactivate in animal feed by binding, in contrast to mycotoxins prevailing in the Southern climates. Meanwhile, both types of toxins present a considerable risk factor for agricultural animal health and performance. A method of adsorbing and rendering harmless for animals an expanded range of both Northern and Southern mycotoxins found in contaminated feed is proposed. According to the invention, a combination of modified plant ligno-polysaccharide material and traditional mycotoxin binding components is added to the feed of agricultural and companion animals in an amount sufficient to abate the negative effects of both types of mycotoxins present.
摘要:
Method is proposed useful to render harmless mycotoxins that contaminate food, animal feed and assist infection of plant hosts by microbial parasites, comprising binding mycotoxins by a novel adsorbent, consisting partially or in full of plant lignocellulosic biomass or isolated biomass components, e.g., acid hydrolysis lignin, enzymatic hydrolysis lignin, coniferous and deciduous wood, bark and needle particles, rice hulls, used coffee grounds, apricot stone shells, almond, walnut, sunflower hulls, cocoa and peanut shells. The materials may be further improved through genetic modification of plants and physicochemical treatment of lignocellulosic biomass, such as micronization. The resulting adsorbent can bind wide range of mycotoxins, including, mycotoxins difficult to bind (Ochratoxin, T-2, Deoxynivalenol, Nivalenol). Ability of porous materials containing lignin to thermally collapse at melting can be used to irreversibly entrap mycotoxins by adsorbing them in a wet system and then closing lignin pore structure under high-temperature treatment, such as drying.
摘要:
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.
