ClearCould probiotics protect against human toxicity caused by polystyrene nanoplastics and microplastics?
This review examines whether probiotics could help protect against the harmful effects of polystyrene nanoplastics and microplastics in the body. Researchers found evidence that probiotic bacteria may counteract plastic-induced gut imbalances, reduce inflammation, and support intestinal barrier function. The study suggests that probiotics represent a promising area of research for mitigating some of the biological effects of microplastic exposure, though more human studies are needed.
Effect of polystyrene nanoplastics on the intestinal histopathology, oxidative stress, and microbiota of Acrossocheilus yunnanensis
Researchers studied the effects of polystyrene nanoplastics on the intestinal health of a freshwater fish species and found significant damage to the gut lining, including ruptured tissue and damaged nutrient-absorbing structures. The nanoplastics also increased oxidative stress markers and shifted the composition of gut bacteria, reducing beneficial species. The findings suggest that nanoplastic exposure can compromise both the physical barrier and microbial balance of fish intestines.
The effect of a polystyrene nanoplastic on the intestinal microbes and oxidative stress defense of the freshwater crayfish, Procambarus clarkii
Researchers tested the acute effects of polystyrene nanoplastics on freshwater crayfish and found that exposure altered the composition of intestinal bacteria and disrupted oxidative stress defenses. Higher concentrations of nanoplastics led to more severe changes in gut microbial diversity and antioxidant enzyme activity. The study adds to growing evidence that nanoplastic pollution can harm the gut health and immune defenses of freshwater organisms.
Impacts of polystyrene nanoplastics on zebrafish gut microbiota and mechanistic insights
Zebrafish exposed to polystyrene nanoplastics showed significant changes in their gut bacteria, with beneficial species like Bifidobacterium declining and potentially harmful bacteria increasing. The nanoplastics physically entered intestinal tissues, causing visible damage to gut cells. This study is relevant to human health because our gut microbiome plays a key role in immunity and digestion, and similar disruption from nanoplastic exposure could contribute to digestive and immune problems.
Concurrent impacts of polystyrene nanoplastic exposure and Aeromonas hydrophila infection on oxidative stress, immune response and intestinal microbiota of grass carp (Ctenopharyngodon idella)
Researchers studied the combined effects of polystyrene nanoplastics and a bacterial infection on grass carp, a common freshwater fish. They found that nanoplastic exposure worsened the impact of the infection by increasing oxidative stress, suppressing immune responses, and disrupting the gut microbiome. The study suggests that nanoplastic pollution in waterways could make fish more vulnerable to disease by weakening their natural defenses.
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.
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.

Researchers exposed grass carp to different sizes and concentrations of polystyrene microplastics for up to 14 days, followed by a depuration period, and assessed physiological and intestinal microbiome effects. The study found that microplastics caused histological damage, oxidative stress, and shifts in gut microbial communities, with smaller particles and higher concentrations producing more severe effects.
Polystyrene nanoplastics affect digestive function and growth in juvenile groupers
Researchers found that polystyrene nanoplastics accumulated in the liver and intestines of juvenile grouper fish, reducing digestive enzyme activity and impairing growth. The nanoplastics also decreased intestinal microbial diversity while increasing the abundance of harmful bacteria such as Vibrio. The study suggests that nanoplastic exposure can significantly compromise digestive function and overall health in marine fish during early development.
Polystyrene nanoplastics disrupt the intestinal microenvironment by altering bacteria-host interactions through extracellular vesicle-delivered microRNAs
Researchers found that polystyrene nanoplastics disrupt the gut lining in mice by altering tiny RNA molecules that control the production of protective proteins in the intestinal barrier. The nanoplastics also caused an imbalance in gut bacteria, creating a chain reaction where damaged gut cells release particles that further weaken the intestinal barrier and change the microbiome.
Probiotics ameliorate polyethylene microplastics-induced liver injury by inhibition of oxidative stress in Nile tilapia (Oreochromis niloticus)
Researchers investigated whether probiotics could protect Nile tilapia from liver damage caused by polystyrene microplastics. The study found that fish pre-fed with probiotics showed significantly reduced oxidative stress markers in the liver compared to those exposed to microplastics alone, suggesting that probiotics may help mitigate microplastic-induced hepatic oxidative damage in fish.
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.
Polystyrene microplastics induce endoplasmic reticulum stress, apoptosis and inflammation by disrupting the gut microbiota in carp intestines
Researchers fed carp polystyrene microplastics and found that the particles disrupted their gut bacteria, killing off beneficial species and promoting those linked to diseases. The microplastics triggered a stress response in intestinal cells that led to inflammation, cell death, and tissue damage. Since carp is a widely eaten fish, these gut health effects raise questions about how microplastics in aquatic environments could affect the safety of fish that humans consume.

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.

Researchers found that the probiotic Lactobacillus rhamnosus GG helped protect mice from liver damage caused by polystyrene microplastic exposure. The probiotic worked by restoring healthy gut bacteria and normalizing liver metabolic pathways disrupted by the microplastics. The study suggests that supporting gut health through beneficial bacteria may help mitigate some of the toxic effects microplastics have on the liver.
The toxicity of polystyrene micro- and nano-plastics on rare minnow (Gobiocypris rarus) varies with the particle size and concentration
Scientists exposed rare minnow fish to polystyrene microplastics and nanoplastics at different sizes and concentrations and found that both caused growth inhibition, tissue damage, and disrupted gut bacteria. Interestingly, larger microplastics at high concentrations were the most disruptive to gut microbiome communities, while nanoplastics caused more oxidative stress. The study shows that the health effects of plastic particles depend on both their size and amount, and that gut health is a key target of microplastic toxicity.
