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.

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.
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.

Perturbation of gut microbiota plays an important role in micro/nanoplastics-induced gut barrier dysfunction
Researchers investigated how micro- and nanoplastics disrupt gut barrier function in mice, finding that different surface chemistries caused varying levels of damage. The study suggests that these plastic particles harm the gut by altering the gut microbiome, which then leads to inflammation and weakening of the intestinal barrier that normally keeps harmful substances out of the body.
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.
Impact of microplastics on the intestinal microbiota: A systematic review of preclinical evidence
Across 28 preclinical studies, microplastics triggered intestinal dysbiosis characterized by increased Firmicutes and Proteobacteria and decreased Bacteroidetes, while increasing gut permeability and elevating pro-inflammatory cytokines including IL-1β, TNF-α, and IL-6.

Researchers investigated how the digestive system affects five common microplastic types and found that digestion altered the surface microstructures of the particles while also negatively impacting probiotic bacteria, suggesting potential health risks from ingested microplastics.
Association between microplastics exposure and gut microbiota and metabolites in older adults: A cross-sectional study
Researchers analyzed fecal samples from 45 older adults to assess the relationship between microplastic exposure and gut microbiota. They found an average of 70 microplastic particles per gram of feces, primarily PVC, butadiene rubber, and polyethylene, and observed that microplastic exposure was associated with changes in gut microbial diversity and metabolite levels. The study suggests that microplastics may influence gut health in older adults by altering bacterial community composition and metabolic pathways.
Probiotics an emerging therapeutic approach towards gut-brain-axis oriented chronic health issues induced by microplastics: A comprehensive review
This review examines how microplastics disrupt the gut-brain axis, the communication system between the digestive system and the brain, leading to chronic health problems like inflammation and neurological issues. The authors highlight probiotics as a promising treatment approach, since beneficial bacteria can help repair gut damage caused by microplastic exposure. The findings suggest that supporting gut health through probiotics may help counteract some of the harmful effects of microplastics on both digestion and brain function.
Oxidized/unmodified-polyethylene microplastics neurotoxicity in mice: Perspective from microbiota-gut-brain axis
Mice exposed to both regular and environmentally weathered polyethylene microplastics developed brain and gut damage, including behavioral changes, weakened gut and blood-brain barriers, and inflammation -- with weathered microplastics causing even more harm. Importantly, treatment with a probiotic (Lactobacillus) and a prebiotic partially reversed these effects, suggesting that gut-friendly supplements might help protect against microplastic-related brain and intestinal damage.
Probiotics improve polystyrene microplastics-induced male reproductive toxicity in mice by alleviating inflammatory response
Researchers found that giving mice probiotics (beneficial bacteria including Lactobacillus and Bifidobacterium) helped protect against reproductive damage caused by polystyrene microplastics. The microplastics disrupted gut bacteria and triggered inflammation that traveled to the testes via the gut-testis connection, reducing sperm quality and testosterone levels. Probiotic treatment restored healthy gut bacteria and reduced the inflammatory response, suggesting that maintaining gut health could help counteract some reproductive harm from microplastic exposure.
Gut Check: Microbiota and Obesity in Mice Exposed to Polystyrene Microspheres

Gut microbiota, a key to understanding the knowledge gaps on micro-nanoplastics-related biological effects and biodegradation
This review explores how micro- and nanoplastics affect the community of microorganisms living in the gut, and how those same gut microbes might be able to break down plastic particles. Swallowed microplastics can disrupt the balance of gut bacteria, potentially leading to various diseases. On the other hand, some gut bacteria can actually degrade plastics into smaller, less harmful molecules, opening a possible avenue for biological cleanup.
Impacts of polystyrene microplastic on the gut barrier, microbiota and metabolism of mice
Researchers exposed mice to polystyrene microplastics for six weeks and found that the particles accumulated in the gut, reduced protective mucus secretion, and damaged the intestinal barrier. The microplastics also significantly altered the composition of gut bacteria, decreasing beneficial species and increasing harmful ones. The study suggests that microplastic ingestion could disrupt gut health in mammals by simultaneously impairing the physical barrier and reshaping the microbiome.
