METHOD FOR DEACTIVATING FUMONISINS AND FUMONISIN DERIVATIVES USING MICROORGANISMS FOR DEACTIVATING FUMONISINS AND A FEED ADDITIVE COMPRISING THIS MICROORGANISM

摘要

The invention relates to a method for deactivating fumonisins and fumonisin derivatives using microorganisms for deactivating the fumonisins and fumonisin derivatives such that neutralizing bacteria or yeasts, selected from the strains Sphingopyxis sp. MTA144 Sphingomondaceae Sphingomonadales DSM 16254, Sphingopyxis sp. MTA5fbll(2)b Sphingomondaceae Sphingomonadales DSM 16257, the fumonisins are enzymatically converted into deamine metabolites by means of a single-stage or multiple-stage reaction. The fumonisins converted enzymatically are present in the feed in an amount from 10/g up to 10/g of the feed, in particular from 2x10/g up to 5x10/g of the feed. The invention also relates to a feed additive for inactivating mycotoxins, in particular fumonisins and fumonisin derivatives.
