In vitro evaluation of the effect of the organic adsorbent on the reduction of mycotoxin Zearalenone

Zearalenone (ZEA) is one of the most important and abundant fungal toxins that causes contamination of food and feed of livestock and poultry as well as serious damages to humans and livestock. The present study investigated the effect of organic adsorbent containing four strains of native Lactobacillus and the yeast cell wall of Saccharomyces cerevisiae on the reduction of the ZEA mycotoxin. Using high-performance liquid chromatography (HPLC), the effects of different factors including incubation time, temperature, as well as synergism of the strains were measured. Based on the obtained results, the investigated organic adsorbent can adsorb the mycotoxin ZEA and reduce its amount in the sample. Also, the heated and culture medium activated adsorbents possessed the best absorption. Evaluation of synergistic of strains showed a greater reduction of the toxin than each strain alone. Therefore, the studied organic adsorbent is proposed to control and reduce mycotoxin ZEA contamination.
