Abstract
Zearalenone (ZEN) can occur in food and feeds impairing farm animal performances and health. In this study, the ability to remove zearalenone by Lactobacillus sp. isolated from rumen was evaluated in vitro. Eight strains isolated from rumen were tested for their abilities to remove zearalenone in MRS liquid medium. The removal rate of these strains ranged from 25.64-69.33%. The highest removing ability of these strains was L. mucosae lm4208. Binding may the mechanism of L. mucosae lm4208 to remove ZEN as no toxin derivatives were observed and removal was not impaired in nonviable bacteria. The ability of removing ZEN by the strain was directly related to the bacterial cell wall structure and composition. Removal was affected by culture time, pH and temperature. Although, removal was decreased in simulated gastric/intestinal fluid, the stain still had the very strong elimination ability. These findings suggest that Lactobacillus sp. from rumen can be exploited as a potential approach of detoxification of ZEN.
