Abstract

The present invention relates to a method for detoxification of feed products contaminated by the mycotoxin aflatoxin.

Description

[0001] Sequence listing involved [0002] This application contains a Sequence Listing in computer readable form. The computer readable form is incorporated herein by reference. field of invention [0003] The present invention relates to a method of detoxifying feed products contaminated with the mycotoxin aflatoxin. Background of the invention [0004] Aflatoxins are naturally occurring mycotoxins produced by various species of Aspergillus, in particular Aspergillus flavus and Aspergillus parasiticus. Aflatoxins are toxic and carcinogenic. [0005] Aflatoxin-producing members of the genus Aspergillus are common and widespread in nature. They can colonize and contaminate grain before harvest or during storage. Host crops are particularly susceptible to Aspergillus infection after prolonged exposure to high humidity or after damage by stress conditions such as drought, conditions that lower the barrier to entry, [0006] Frequently affected crops include cereals such as...
