Detoxification of Zearalenone by viable and inactivated cells of Planococcus sp

The capacity of Planococcus sp. strain S118 to remove Zearalenone (ZEN) from liquid medium in varying conditions was investigated. The results indicated that Planococcus sp. S118 removed ZEN by binding process. Strain S118 significantly reduced the levels of ZEN in the liquid medium; the viable and heat-inactivated bacteria could remove 21.82% and 47.82% of ZEN, respectively. Heat, acid, and Triton-100 treatment significantly enhanced the capability of removing ZEN. The detoxifying capability depended on the incubation period, concentration of bacteria, pH, and temperature. Planococcus sp. S118 likewise possessed the capability to remove Zearalanone (ZAN), which is one of ZEN analogues. The viable and heat-inactivated bacteria could remove 16.36% and 34.26% of ZAN, respectively. The detoxifying capability of ZEN and ZAN by heat-inactivated bacteria were significantly influenced by each other.
