ClearAdsorption 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.

Using microbes to produce bioplastics that break down naturally could help reduce persistent microplastic pollution.
Lactobacillus plantarum reduces polystyrene microplastic induced toxicity via multiple pathways: A potentially effective and safe dietary strategy to counteract microplastic harm
Researchers found that Lactobacillus plantarum, a probiotic bacterium commonly found in fermented foods, can reduce the harmful effects of polystyrene microplastics in mice through multiple pathways. The bacteria worked by binding directly to plastic particles to help remove them from the body, reducing oxidative damage, repairing the intestinal barrier, and regulating bile acid metabolism. This suggests that certain probiotics could be a safe dietary strategy to help counteract some of the negative health effects of microplastic exposure.
Influence of biofilms on the adsorption behavior of nine organic emerging contaminants on microplastics in field-laboratory exposure experiments
Researchers studied how natural biofilms that form on microplastics in lake water affect the adsorption of nine emerging organic contaminants.

Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.
Reviewing the role of microplastics as carriers for microorganisms in absorbing toxic trace elements
This review examines how microplastics serve as carriers for both harmful bacteria and toxic metals in the environment. Bacteria colonize microplastic surfaces and form biofilms, which can concentrate dangerous trace elements and help spread pathogens to new areas. This dual role as a transport vehicle for both chemical and biological contaminants increases the potential risk to human health through contaminated water and food.
