ClearDetermination 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.
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.

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. Since gut microbiome stability depends on these beneficial bacteria, this research suggests that nanoplastic ingestion could undermine the health benefits of probiotics and more broadly disrupt the gut microbial community.
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.
Bacillus subtilis, a promising bacterial candidate for trapping nanoplastics during water treatment
Researchers found that the probiotic bacterium Bacillus subtilis can effectively trap polystyrene nanoplastics from water, with most nanoparticles clustering around the bacterial cells. At a concentration of 10 mg/L, over 73% of the nanoplastics' environmental state was altered through interaction with the bacteria. The study suggests B. subtilis could be a promising candidate for biological nanoplastic removal during water treatment, while simultaneously processing nitrogen compounds.
Lactobacillus delbrueckii subsp. bulgaricus 2038 and Streptococcus thermophilus 1131 suppress polystyrene nanoplastic transcellular permeability and internalization by intestinal epithelial cells
Researchers found that two yogurt starter bacteria, Lactobacillus delbrueckii subsp. bulgaricus 2038 and Streptococcus thermophilus 1131, significantly reduced the uptake and transport of polystyrene nanoplastics by intestinal epithelial cells. The study suggests these specific strains, even when non-viable, may help limit nanoplastic accumulation in the body by suppressing their internalization in the gut lining.

Interfacial Interactions between Escherichia coli and Polystyrene Nanoplastics: a Physicochemical Perspective
When nanoplastic particles encounter bacteria in the environment, the nature of that interaction affects how plastics move through ecosystems and whether they carry pathogens. This study examined how polystyrene nanoparticles (both plain and amine-modified) interact with E. coli at a physicochemical level, finding that attachment depended strongly on particle surface charge, pH, and concentration. The amine-modified particles bound more readily to bacterial surfaces and altered bacterial membranes, suggesting that surface chemistry—which changes as plastics weather in the environment—substantially influences the ecological behavior of nanoplastics and their potential to ferry microorganisms to new locations.
Microplastics and probiotics: Mechanisms of interaction and their consequences for health
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.
Charge-specific impacts of polystyrene nanoplastics on acidogenesis and biofilm adaptation in Ethanoligenens harbinense
Positively and negatively charged polystyrene nanoplastics had different effects on acidobacteria (a major group of soil bacteria), with charge-specific impacts on community composition and activity. The findings indicate that the surface chemistry of nanoplastics, not just their size, determines ecological impact.
Nanoplastics from single-use polyethylene terephthalate bottles impair the functionality of human gut-dwelling Lactobacillus rhamnosus and induce toxicity in human cells
Researchers synthesized nanoplastics from single-use PET water bottles and tested their effects on the gut probiotic Lactobacillus rhamnosus, red blood cells, and human lung cells. They found that the nanoplastics reduced probiotic survival in a dose-dependent manner, damaged cell membranes, and impaired the bacteria's beneficial functions including antioxidant activity. The study provides evidence that nanoplastics released from everyday plastic bottles could disrupt important gut bacteria and harm human cells.

Adsorption interactions between typical microplastics and enrofloxacin: Relevant contributions to the mechanism
This study investigated how common microplastics (polyethylene, PVC, and polystyrene) absorb the antibiotic enrofloxacin from the environment. The researchers found that microplastics can effectively bind antibiotics through multiple chemical mechanisms, with the strength of binding depending on water conditions like acidity. This is concerning because microplastics carrying antibiotics could transport them into the food chain, potentially contributing to antibiotic resistance and affecting human health.
Adsorption characteristics of antibiotics on microplastics: The effect of surface contamination with an anionic surfactant
Researchers found that the common anionic surfactant SDBS coating polystyrene and polyethylene microplastics significantly altered their adsorption of the antibiotics oxytetracycline and norfloxacin. SDBS changed the surface charge and hydrophobicity of MPs in ways that increased antibiotic binding, suggesting surfactant-contaminated MPs pose a greater risk as antibiotic vectors in aquatic environments.

Exposure to polystyrene nanoparticles leads to changes in the zeta potential of bacterial cells
Researchers exposed two common bacteria — Staphylococcus aureus and Klebsiella pneumoniae — to 100-nanometer polystyrene plastic particles and found that the nanoparticles attached to bacterial cell surfaces, changing their electrical charge (zeta potential) without killing the cells. This matters because nanoplastics interacting with bacteria in the human gut microbiome could alter microbial behavior in ways that are not yet fully understood.

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.

Researchers discovered that two species of Bacillus bacteria, commonly used to promote plant growth in agriculture, can break down polystyrene nanoplastics by oxidizing them. While high doses of nanoplastics initially harmed the bacteria, both species recovered and grew normally over time. The findings point to a potential biological approach for cleaning up nanoplastic pollution in agricultural soils.
