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.
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.
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.

Researchers screened 784 bacterial strains and identified two probiotic strains that can stick to microplastic particles in the gut and help remove them from the body. In mice, these probiotics increased microplastic excretion by 34% and reduced the amount of plastic remaining in the intestine by 67%. This is the first study to show that specific probiotics could help the body get rid of ingested microplastics and reduce gut inflammation caused by them.
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.

This review explores how microplastics interact with probiotics and what that means for gut health. Researchers summarized evidence showing that microplastics can disrupt the gut lining, alter the microbiome, and trigger inflammation, while certain probiotic strains may help counteract these effects by reducing oxidative stress and supporting the intestinal barrier. The study also discusses the emerging possibility of using engineered probiotics for environmental microplastic cleanup.
Micro-nanoplastics inhibit extracellular polymeric substance and lactate synthesis via perturbing glucose metabolism of Lacticaseibacillus rhamnosus
Researchers found that micro- and nanoplastics — especially nanoscale PET particles — impair the probiotic bacterium Lactobacillus rhamnosus by disrupting central carbon metabolism, reducing its production of lactic acid and protective extracellular polysaccharides, raising concerns that microplastic ingestion could compromise the gut benefits of probiotic bacteria.
Polystyrene and polytetrafluoroethylene nanoplastics affect probiotic bacterial characteristics and penetrate their cellular membrane
This study found that polystyrene and PTFE nanoplastics damage the membranes and viability of probiotic bacteria in ways that differ by particle surface chemistry and bacterial strain.

Researchers systematically reviewed 15 mouse studies and found that exposure to polystyrene micro- and nanoplastics consistently disrupted gut bacteria — reducing beneficial species like Lactobacillus and increasing harmful ones — while also altering metabolic pathways throughout the body. Nanoplastics caused more severe microbiome disruption than larger microplastics, highlighting a serious health concern for humans.
The microplastic-crisis: Role of bacteria in fighting microplastic-effects in the digestive system
This review examines how microplastics affect the human digestive system and explores whether certain bacteria could help counteract the damage. Microplastics disrupt the gut by altering microbial communities, interfering with digestive enzymes, and damaging the protective mucus lining. The authors highlight the potential for probiotic bacteria to bind to microplastics, reduce inflammation, and help repair the gut environment, offering a possible protective strategy against microplastic-related digestive harm.
