Abstract:Heavy metals pollution is one of the hot issues in food safety. The use of food grade lactic acid bacteria to adsorb heavy metals has become a new research area. In this review article, we introduce the sources and harms of mercury, cadmium, and lead pollutions in the environment and food. We also summarize the potential application and mechanisms of adsorbing heavy metals using lactic acid bacteria. This review provided a feasible way to develop efficient adsorbent for lactic acid bacteria adsorbing heavy metals.
