Sažetak
Zearalenone is mycotoxin harmful to the health of humans and animals and is present in food and feed. Therefore, last few decades, great attention is paid to the development of biological detoxification methods with reference to the application of lactic acid bacteria in binding and removal of mycotoxins from food and feed. The aim of this work was to investigate the ability of lactic acid bacteria Lactobacillus rhamnosus GG (ATCC 53103) and Lactobacillus plantarum A1 to bind zearalenone unto the cell surface. The results showed that Lactobacillus rhamnosus (GG ATCC 53103) and Lactobacillus plantarum A1 can bind significant concentration of zearalenone, depending on the bacteria concentration in the medium and the incubation time. However, with longer time of incubation part of bounded mycotoxins were released back into the medium which indicates that the reaction of adhesion of toxin to the bacterial cells is reversible. Determination of zearalenone concentration was performed by competitive ELISA test.
