Study on the degradation of zearalenone by Micrococcus luteus.

Objective To optimize the conditions for the degradation of Zearalenone by Micrococcus luteus.Method The degradation efficiency of Micrococcus luteus cultured under different conditions(medium,temperature,initial pH,rotational speed,time and type of metal ions) were evaluated by HPLC.Result 99% of Zearalenone was degraded within 120 h in the LB broth by Micrococcus luteus under the conditions: initial pH 7.0,37 ℃,180 r/min.Conclusion The main factors influencing the degradation efficiency of ZEN are the type of medium,pH and metal ions in the broth.
