Lactic acid bacteria as promising dietary-derived bioadsorbents for foodborne contaminants: Mechanism, application advances and future perspectives
Summary
This review examined lactic acid bacteria as potential bioadsorbents for foodborne contaminants including mycotoxins and microplastics. Researchers found that these beneficial bacteria can bind and sequester various pollutants through cell surface interactions, suggesting that dietary lactic acid bacteria may offer a safe, cost-effective approach to reducing human exposure to contaminants in the food chain.
Foodborne contaminants, such as mycotoxins and microplastics, pose significant threats to human health due to their high toxicity and persistence in the food chain, thus necessitate effective mitigation strategies. Lactic acid bacteria (LAB), characterized by high efficiency, cost-effectiveness, safety, and environmental friendliness, offer a promising solution for adsorbing these pollutants. This review systematically explores the roles, binding locations, interaction forces, and molecular mechanisms underlying LAB-contaminant interactions, as well as the thermodynamics and kinetic properties of the adsorption processes. Notably, LAB strains with outstanding adsorption capabilities are spotlighted, along with innovative enhancement strategies: optimized culture conditions, co-culture systems, nanoparticle functionalization, immobilized cells, and combinations with bio-adsorbents. The review further demonstrates the applications of LAB in ensuring safe food production and maintaining biological health. Future directions include multi-omics-driven gene discovery, genetic engineering techniques for precision regulation, and machine learning for adsorption optimization, advancing mechanistic insights and interdisciplinary solution.

Adsorption abilities and mechanisms of Lactobacillus on various nanoplastics
Researchers tested whether Lactobacillus, a common probiotic bacterium, could adsorb nanoplastic particles made of polypropylene, polyethylene terephthalate, and polystyrene. They found that the bacteria could efficiently bind all three types of nanoplastics through electrostatic interactions and hydrogen bonding on their cell surfaces. The study suggests that lactic acid bacteria may have potential as a biological method for reducing nanoplastic contamination in food.
Novel Approaches in Establishing Chemical Food Safety Based on the Detoxification Capacity of Probiotics and Postbiotics: A Critical Review
This review examines emerging evidence that probiotics and their metabolic byproducts (postbiotics) can help neutralize environmental contaminants in food, including bacterial toxins, mycotoxins, pesticides, heavy metals, and microplastics. Researchers found that various probiotic strains can bind to, transform, or break down these harmful substances through multiple mechanisms. The study highlights biological approaches using beneficial microorganisms as a practical and cost-effective strategy for improving food safety.
Efficient biosorption of nanoplastics by food-derived lactic acid bacterium
Researchers identified a food-derived lactic acid bacterium, Leuconostoc mesenteroides CBA3656, that efficiently binds and removes nanoplastics across a wide range of conditions including varying pH, temperature, and concentrations. In animal experiments, the strain significantly enhanced fecal excretion of nanoplastics, suggesting it could serve as a promising microbial approach for reducing nanoplastic burden in intestinal environments.
Lactic acid bacteria reduce polystyrene micro- and nanoplastics-induced toxicity through their bio-binding capacity and gut environment repair ability
Researchers found that lactic acid bacteria, the kind used in yogurt and fermented foods, can reduce the toxic effects of polystyrene micro and nanoplastics in mice. The bacteria worked by physically binding to the plastic particles and by repairing damage to the gut lining and restoring healthy gut bacteria populations. This suggests that probiotics could be a practical way to help protect the digestive system from the harmful effects of microplastic exposure through food and water.
Determination of the ability of native potential probiotic lactobacillus strains in nanoplastic bioremoval in an in-vitro Model
Researchers tested 88 native probiotic Lactobacillus strains for their ability to bind and remove polystyrene nanoplastics in laboratory conditions, finding that a cocktail of three strains achieved up to 77% removal. The most effective strain, L. plantarum RP13, showed strong nanoplastic adhesion confirmed by microscopy imaging. The study suggests that certain probiotic bacteria may have potential as a biological approach to reducing nanoplastic exposure in the gastrointestinal tract.
