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.
Effects of repeated intragastric administrations with heat-inactivated Mycobacterium aurum DSM 33539 on the stress-induced aggravation of dextran sulfate sodium (DSS) colitis in C57BL/6N mice
Researchers tested whether a heat-inactivated preparation of the soil bacterium Mycobacterium aurum could protect mice from stress-aggravated intestinal inflammation. They found that oral administration of M. aurum reduced the severity of stress-induced colitis and helped maintain intestinal barrier integrity. The study suggests that certain beneficial environmental bacteria may help protect gut health under stressful conditions, though more research is needed.
Gut microbiota and liver metabolomics reveal the potential mechanism of Lactobacillus rhamnosus GG modulating the liver toxicity caused by polystyrene microplastics in mice
Researchers found that the probiotic Lactobacillus rhamnosus GG helped protect mice from liver damage caused by polystyrene microplastic exposure.

A Lactobacilli diet that confers MRSA resistance causes amino acid depletion and increased antioxidant levels in the C. elegans host
A Lactobacillus diet in C. elegans worms produced resistance to MRSA infection by depleting certain amino acids and increasing antioxidant levels in the host. The study shows that probiotic bacteria can protect against pathogenic bacteria through metabolic changes rather than direct competition. These findings support further research into probiotics as alternatives to traditional antibiotics.

Researchers tested whether the probiotic supplement SLAB51 could counteract the harmful effects of bisphenol A (BPA), a plastic-derived chemical, in zebrafish and found it significantly restored healthy gut bacteria, reduced liver damage, and protected the brain — suggesting probiotics may help offset harm from plastic-associated chemical exposure.
Bioactive compound and chemical characterization of lactic acid bacteria from fermented food as bio-preservative agents to control food-borne pathogens
Thai researchers screened lactic acid bacteria from fermented foods and identified four Lactobacillus species with antibacterial activity against common food pathogens including E. coli and Staphylococcus aureus. The best-performing strain showed promising properties for use as a natural food preservative.
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.
Prevention of Loperamide-Induced Constipation in Mice and Alteration of 5-Hydroxytryotamine Signaling by Ligilactobacillus salivarius Li01
Researchers found that the probiotic Ligilactobacillus salivarius Li01 alleviates constipation in mice by modulating the serotonin signaling pathway, improving intestinal barrier function, and altering gut microbiota composition.
The impact of microplastics on the mice gut microbiome: a meta-analysis
This meta-analysis pools data from multiple mouse studies to assess how ingested microplastics affect gut bacteria. It found that microplastic exposure can alter the balance of the gut microbiome, which is important because gut health is closely tied to immune function, digestion, and overall well-being.
Probiotics as Modulators of Microplastic-induced Toxicity: A Systematic Review
This systematic review found that probiotics can reduce microplastic-induced toxicity in animal models by restoring gut microbiota balance, reducing oxidative stress, and modulating inflammatory responses. The findings suggest that probiotic supplementation may help mitigate the harmful effects of unavoidable microplastic exposure, though human clinical trials are still needed.
Lactiplantibacillus plantarum P101 Alleviates Liver Toxicity of Combined Microplastics and Di-(2-Ethylhexyl) Phthalate via Regulating Gut Microbiota
Researchers found that the probiotic Lactiplantibacillus plantarum P101 reduced liver damage caused by combined exposure to microplastics and the plasticizer DEHP in mice. The probiotic reversed oxidative stress and inflammation in the liver and intestines while reshaping the gut microbiota. The study suggests that probiotic supplementation may offer a promising strategy for mitigating the toxic effects of co-exposure to microplastics and plastic-associated chemicals.
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.
Interactions between polystyrene-derived micro- and nanoplastics and the microbiota: a systematic review of multi-omics mouse studies
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 potential influence of food additives and contaminants on the gut microbiota: A comprehensive review
This comprehensive review examines how food additives and contaminants, including pesticides, heavy metals, microplastics, and antibiotics, affect the gut microbiota. Researchers found that these substances can disrupt the balance of gut microbes, leading to inflammation, gastrointestinal injury, and altered production of beneficial short-chain fatty acids. The study emphasizes the need for further research into the mechanisms by which dietary contaminants affect gut health and overall wellbeing.

The study also discusses the emerging possibility of using engineered probiotics for environmental microplastic cleanup.
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.
Microplastics and their interactions with microbiota
This review examines how microplastics interact with microbiota (the communities of microorganisms in the environment and in living bodies). Microplastics can carry harmful bacteria and disrupt the natural balance of microbial communities in soil, water, and the human gut. The disruption of gut microbiota by microplastics is particularly concerning because a healthy gut microbiome is essential for immune function, digestion, and overall health.
