| microbiologicals for deactivating mycotoxins. | mycotoxins are secondary metabolites of fungi affecting human and animal health. five classes of mycotoxins are of major concern in animal husbandry, namely aflatoxins, trichothecenes, zearalenone, ochratoxins, and fumonisins. due to their diverse structure these fungal toxins are able to cause a great variety of acute symptoms in animals. clay minerals have been used in animal nutrition to bind mycotoxins, but the binders are only very specific for aflatoxins but not for other toxins. a novel s ... | 2006 | 16715543 |

| cleavage of zearalenone by trichosporon mycotoxinivorans to a novel nonestrogenic metabolite. | zearalenone (zon) is a potent estrogenic mycotoxin produced by several fusarium species most frequently on maize and therefore can be found in food and animal feed. since animal production performance is negatively affected by the presence of zon, its detoxification in contaminated plant material or by-products of bioethanol production would be advantageous. microbial biotransformation into nontoxic metabolites is one promising approach. in this study the main transformation product of zon forme ... | 2010 | 20118365 |
