Abstrakt: Zearalenone (ZEN) is an estrogenic mycotoxin produced by the Fusarium species and induces severe reproductive disorders in animals thus a major concern in the livestock industry. Probiotic bacteria treatments have been shown to inactivate mycotoxins, therefore, in this study, we investigated the effect of two commercial probiotic feed additives on the sequestration of ZEN. Commercial probiotic blends containing clay-based binder with Aspergillus niger, Bacillus licheniformis, Bacillus pumilus, and Bacillus subtilis at various proportions from BioMatrix International were incubated with ZEN in a time-dependent manner and then analyzed by Enzyme-Linked Immunosorbent Assay (ELISA) to quantify unbound ZEN. Sequestration of ZEN was further verified by using MCF-7 cell-based cytotoxicity and/or cell proliferation assays. ZEN, or probiotic mix, was nontoxic to MCF-7 cells. Probiotic blends decreased ZEN concentration by 45% (∼100 μg L-1) and prevented ZEN from inducing MCF-7 cell proliferation (20%-28% reduction). The probiotic feed supplements tested show a potential utility in ZEN neutralization.
