Zearalenone (ZEA) contamination in food samples plays a critical role in food safety, since it causes serious
health problems. Usage of microorganisms, such as lactic acid bacteria (LAB), is a promising new
approach for detoxification. Eight Lactobacillus pentosus strains were evaluated for their ability to remove
ZEA from a sodium acetate buffer solution with initial ZEA concentrations of 5.51–74.70 μg/mL. The adsorption
capacity increased with increasing ZEA concentrations. The strain JM0812 showed the highest
adsorption capability, at 83.17%, in solution containing 74.70 μg/mL ZEA, followed by UM054 (82.78%)
and UM055 (81.69%), respectively. Three adsorption isotherms were applied to predict the removal effi-
ciency of ZEA and the Freundlich isotherm appeared to have the best-fit for ZEA sorption onto bacterial
cells. Our results indicate that Lb. pentosus strains are novel promising strains to reduce mycotoxin contamination
in food products.
