Fungal toxins .. Biological compounds produced by a group of fungi have the ability to produce secondary metabolites when they grow on a suitable environment



Fungal toxins are a family of biological compounds produced by a group of fungi that have the ability to produce secondary metabolic compounds when grown on a suitable environment. Secondary metabolic products of fungi are biologically active and non-antigenic toxins in the sense that their molecular structure is free from the components that are paid The organism to form antibodies, and most of them are toxic to humans, animals, plants and microorganisms. The toxic products of humans and animals are called "Mycotoxins".
The toxic compounds of microorganisms are called antibiotics, which often cause abnormal biological changes in the organism. In general, it is agreed that the secondary metabolic products of the mycotoxins, And also on the resulting poisoning processes expression of mycotoxicosis.
In general, mycotoxins reach human and animal food through contamination of food or food provided by the fungus. These are called direct contamination. The food encourages the growth of the fungus either during the different stages of production or during transportation or storage.
Or contamination may be indirect as a result of contamination of components of food with mycotoxin, and this is by feeding human animal products from animals previously fed on feed contaminated with fungal toxins and the second way is the most dangerous.
These toxins can be produced in the field before harvest or after harvest and during storage of different materials.
As a result of fungus growth, it metabolizes and produces fungal toxins, and fungi growth requires specific environmental conditions
Such as: increased humidity - poor storage - an abundance of oxygen - contamination with fungi - mechanical damage.
There are many fungal species (Aspergillus - Penicillium - Fusarium - Stakipotros - Alternaria and others) which have the ability to produce various fungal toxins. Produces the sex of Aspergillus toxin Aflatoxin - Glyotoxin - Stratogoxin - Cyclopsonic acid - Amodine - Citrine - Ochratoxin - Cogic acid - . The genus pennilium produces the toxins of citrine-patulin-trobratoxin-ocratoxin-ocratoxin-cyclophosphate.
The sex of the fusarium is produced by the zeralins and the tricosins.
The sex of stacipotros produces toxins (satoratoxin-furocarine-ruidine).
The genus Alttenaria produces toxins (ternariol-ternariol methyl ether - tetraxine - tinoin - tinozonic acid).
There are several types of aflatoxin (B1-B2-C1-C2)
However, most of the toxicity of aflatoxin B1 is enough for 2.2 milligrams of aflatoxin to damage the liver.
Aflatoxin is often exposed to the reduction enzymes and converted into aflatoxico, or oxidative enzymes, and is converted into aflatoxin M1, m 2, which appears in the milk, or is transformed into aflatoxin K1, A1, E1 in the liver.
All these derivatives are related to certain acids or sulfates and are converted into compounds that dissolve in water and can be disposed of by the body except aflatoxin B1.
