The present invention provides a bacterial microorganism having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. The present invention also provides a method for the isolation and utilization of a zearalenone-degradation gene encoding a gene product having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. In another embodiment, the present invention provides for the generation of transformants into which the zearalenone-degradation gene has been introduced, thereby providing the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone to said transformants. The present invention further provides a method for detoxification of plants pre- or post-harvest using microbes having the ability to degrade or detoxify zearalenone or derivatives or analogs of zearalenone. The invention also provides a method for detoxification of plants pre- or post-harvest using the zearalenone-degradation gene.
A method of degrading zearalenone in or on a plant comprising topically applying a composition comprising a biologically pure culture of bacterium which degrades zearalenone to said plant, wherein said bacterium is selected from the group consisting of the Rhodococcus species and the Nocardia species.
A method of degrading zearalenone on a harvested grain comprising topically applying a composition comprising a biologically pure culture of bacterium which degrades zearalenone to said harvested grain, wherein said bacterium is selected from the group consisting of the Rhodococcus species and the Nocardia species.
