Polypeptide for the enzymatic detoxification of zearalenone, isolated polynucleotide, and associated additive, use and method

A method for enzymatic detoxification of zearalenone comprising the following steps:

• preparing a recombinant isolated polypeptide by utilizing a yeast strain, which is transformed with a polynucleotide for expressing the polypeptide;
• and
• reacting the polypeptide with zearalenone, wherein the polypeptide is a monooxygenase converting the keto group in position 7 of zearalenone into an ester group, and wherein the polypeptide comprises the amino acid sequence of SEQ ID NO:
• 1, SEQ ID NO:
• 2 or SEQ ID NO:
• 3 or an amino acid sequence having at least 90% sequence identity to the amino acid sequence of SEQ ID NO:
• 1, SEQ ID NO:
• 2 or SEQ ID NO:
• 3;
• wherein the monooxygenase is a Baeyer-Villiger monooxygenase and a cyclohexanone monooxygenase.
