Abstract
Acrylamide (AA) present in food is considered a harmful compound for humans, but it exerts impact on microorganisms too. The aim of the study was to evaluate the impact of AA (at conc. 0-10 µg/mL) on the growth of bacteria (Leuconostoc mesenteroides, Lactobacillus acidophilus LA-5) and yeasts (Saccharomyces cerevisiae, Kluyveromyces lactis var. lactis), which naturally occur in food products. Moreover, we decided to verify whether these microorganisms could decompose acrylamide. Our results proved that AA can stimulated the growth of L. acidophilus and K. lactis. We have also reported, to the best of our knowledge for the first time, that probiotic strain of bacteria L. acidophilus LA-5 is able to degrade AA by amidase production and hence can utilize AA as a source of carbon and nitrogen if they lack in the environment. The conducted Response Surface Methodology indicated that pH as well as incubation time and temperature significantly influenced the amount of ammonia released from acrylamide by the bacteria. Concluding, our studies suggest that some strains of bacteria present in milk fermented products can exert additional beneficial impact by acrylamide degradation and preventing against its harmful impact on human body and other members of intestinal microbiota.
