ClearAntibiotic-driven shifts in bacterial dynamics of the polyethylene terephthalate and low density polyethylene plastisphere in wastewater treatment systems
Researchers studied how antibiotic exposure shifts the bacterial communities colonizing PET and LDPE microplastic surfaces in activated sludge from wastewater treatment plants, finding that antibiotics altered plastisphere microbial composition and increased antibiotic resistance gene prevalence.
Comprehensive profiling and risk assessment of antibiotic resistomes in surface water and plastisphere by integrated shotgun metagenomics
Researchers used shotgun metagenomics to compare antibiotic resistance genes in surface water versus the biofilms that form on microplastic surfaces, known as the plastisphere. They found that microplastics harbored distinct microbial communities with different antibiotic resistance profiles compared to surrounding water. The study raises concerns that microplastics may serve as vehicles for spreading antibiotic resistance in aquatic environments.
Microplastics as hubs enriching antibiotic-resistant bacteria and pathogens in municipal activated sludge
Researchers demonstrated that microplastics in municipal wastewater treatment plants act as "hubs," selectively concentrating antibiotic-resistant bacteria and pathogens in their surface biofilms, with antibiotic-resistance genes enriched up to 4.5-fold compared to sand particles — raising concerns about microplastics spreading drug-resistant microbes into the environment.
Antibiotic resistance in plastisphere
Researchers reviewed antibiotic resistance in the plastisphere — the microbial community colonizing plastic surfaces in aquatic environments — finding that plastic properties and aging influence the enrichment and horizontal transfer of antibiotic resistance genes, and that aged microplastics pose elevated risks due to increased adsorption of resistant bacteria.
Bacterial dynamics of the plastisphere microbiome exposed to sub-lethal antibiotic pollution.
This study investigated how sub-lethal antibiotic concentrations in water interact with microplastic-associated biofilm communities (the plastisphere), finding that combined pollution alters bacterial dynamics and may contribute to antibiotic resistance selection in aquatic environments.
Alteration of microbial mediated carbon cycle and antibiotic resistance genes during plastisphere formation in coastal area
Researchers investigated how microplastic surfaces in coastal environments develop biofilm communities, known as the plastisphere, and whether these biofilms enrich antibiotic resistance genes. The study found that incubation time, habitat type, and microplastic aging state all significantly influenced biofilm composition, and that aged microplastics accumulated more antibiotic resistance genes than new ones, suggesting microplastics may serve as vectors for spreading resistant bacteria.
Growth and prevalence of antibiotic-resistant bacteria in microplastic biofilm from wastewater treatment plant effluents
Researchers studied antibiotic-resistant bacteria growing in biofilms on microplastic surfaces in wastewater treatment plant effluent. The study found that microplastic biofilms accumulated antibiotic-resistant bacteria including Pseudomonas, Aeromonas, and Bacillus, and that these biofilms harbored higher concentrations of resistance genes compared to surrounding water, suggesting microplastics may serve as reservoirs for antibiotic resistance.
Integration of metagenomic analysis and metabolic modeling reveals microbial interactions in activated sludge systems in response to nanoplastics and plasticizers
Researchers combined amplicon sequencing, metagenomics, and metabolic modeling to show that PVC nanoplastics and the plasticizer DEHP alter microbial community interactions in activated sludge wastewater systems — with DEHP exposure promoting cooperative metabolic relationships and both pollutants shifting interspecies iron and antioxidant exchange pathways.
Responses of bacterial communities and resistance genes on microplastics to antibiotics and heavy metals in sewage environment
Polyvinyl chloride microplastics in sewage enriched pathogenic bacteria and antibiotic resistance genes on their surfaces, and the presence of heavy metals and antibiotics altered but did not eliminate this enrichment over time. The findings suggest microplastics in wastewater environments could facilitate the spread of antibiotic resistance through the microbial community.
Aquatic Biofilms and Plastisphere
This review examined aquatic biofilms and plastisphere communities that colonize microplastic surfaces, discussing how plastic substrates select for distinct microbial assemblages and may harbor pathogens and antibiotic resistance genes.
Microplastic Microbiome Interactions: Emerging Threats and Bioremediation Potentials
This review examines the plastisphere — microbial communities that colonize plastic surfaces — covering how these biofilms influence the fate and toxicity of microplastics while acting as vectors for pathogens and antibiotic resistance genes, and discussing their potential for bioremediation.

Decoding the microplastic Micro-interface: a complex Web of gene transfer and pathogenic threats in wastewater
Researchers used metagenomics to study how microplastic surfaces in wastewater treatment systems serve as hotspots for antibiotic resistance genes and pathogenic bacteria. They found that microplastic micro-interfaces supported more robust microbial networks and facilitated horizontal gene transfer of resistance and virulence genes more actively than surrounding environments. The study suggests that microplastics in wastewater may accelerate the spread of antibiotic resistance and increase pathogenicity risks.
Wastewater treatment alters microbial colonization of microplastics
Analysis of microplastics and their biofilms across raw sewage, effluent, and sludge at two wastewater treatment plants found that >99% of influent MPs were retained in sludge, and that wastewater treatment substantially altered biofilm microbial composition, enriching bioflocculation-associated taxa.
Taxonomic variation, plastic degradation, and antibiotic resistance traits of plastisphere communities in the maturation pond of a wastewater treatment plant
Researchers placed different types of weathered plastics in a wastewater treatment pond for up to a year and studied the microbial communities that grew on them. The study suggests that the bacteria colonizing plastics in wastewater were shaped more by time and water depth than by the type of plastic, and that these communities may carry genes related to plastic degradation and antibiotic resistance.
Wastewater plastisphere enhances antibiotic resistant elements, bacterial pathogens, and toxicological impacts in the environment
Researchers reviewed how microplastics in wastewater form biofilms known as the plastisphere, which can harbor antibiotic-resistant bacteria and human pathogens. The study found that conventional wastewater treatment plants are unable to fully remove micro- and nano-sized plastic particles, allowing them to enter natural environments. Evidence indicates the wastewater plastisphere enhances the spread of antibiotic resistance elements and bacterial pathogens, posing risks to both ecological and human health.
The plastisphere ecology: Assessing the impact of different pollution sources on microbial community composition, function and assembly in aquatic ecosystems
Researchers studied the microbial communities living on microplastic surfaces (called the plastisphere) across four different aquatic sites and found that plastics host a distinctly different mix of microbes than the surrounding water, shaped by local pollution sources. These plastic-surface microbes also carry more antibiotic resistance genes and show greater potential for breaking down plastics, making the plastisphere both a health concern and a potential bioremediation resource.
Plastisphere enrich antibiotic resistance genes and potential pathogenic bacteria in sewage with pharmaceuticals
Researchers investigated how tetracycline, ampicillin, and triclosan affected antibiotic resistance genes and microbial communities on PVC and PE biofilms in sewage, finding that MPs enriched multidrug resistance genes and mobile genetic elements, with PE promoting greater microbial attachment than PVC.
Ecosystem-specific composition and drivers of plastisphere resistome in freshwater and marine environments
This comparative meta-analysis of metagenomic data found that microplastics in freshwater and marine environments harbor distinct antibiotic resistance gene profiles, with freshwater plastispheres showing greater resistome diversity. Microplastics serve as hotspots for antibiotic resistance gene propagation, with mobile genetic elements facilitating transfer to potentially pathogenic bacteria.
Wastewater discharges and polymer type modulate the riverine plastisphere and set the role of microplastics as vectors of pathogens and antibiotic resistance
Researchers investigated how wastewater treatment plant discharges and polymer type shape microbial communities on microplastics in a river environment. They found that microplastics harbored significantly higher microbial diversity than surrounding water, and that wastewater discharges led to a 2.3-fold increase in antibiotic resistance gene abundance on the plastic surfaces. Different polymer types, including polyethylene, polypropylene, and PET, each attracted distinct microbial communities with varying levels of pathogens and resistance genes.
High-throughput sequencing data of the microbiota and antibiotic resistance genes from biofilms on polystyrene and nylon rope incubated in Bergen harbor.
Researchers used high-throughput metagenomics sequencing to characterize the microbiota and antibiotic resistance genes in biofilms ('plastisphere') formed on polystyrene and nylon ropes submerged in Bergen harbour, Norway for four weeks.
Different microbial assemblage colonized on microplastics and clay particles in aerobic sludge treatment
In an aerobic sludge treatment system, polystyrene microplastics (PSMPs) hosted more diverse and abundant bacterial communities than polypropylene MPs or natural clay particles, and each substrate type shaped its own distinct microbial niche. This matters because the unique microbiomes that form on plastic surfaces in wastewater systems may alter treatment efficiency and carry potentially harmful organisms into receiving environments.
High-throughput absolute quantification sequencing reveals the adaptive succession and assembly pattern of plastisphere communities in municipal sewer systems: Influence of environmental factors and microplastic polymer types
Microplastics in municipal sewer systems develop their own distinct microbial communities (the 'plastisphere') that are shaped both by the type of plastic polymer and by environmental conditions like temperature and nutrient levels. The study found that different plastic types selectively enriched different microbes, including potential pathogens, meaning sewers could be hotspots for microplastic-mediated spread of harmful bacteria into waterways. This research highlights an understudied but practically important dimension of urban microplastic contamination.
New insight into the effect of microplastics on antibiotic resistance and bacterial community of biofilm
Researchers found that different types of microplastics promote distinct biofilm communities and enhance antibiotic resistance gene proliferation compared to natural substrates, suggesting microplastics serve as unique platforms for the spread of antimicrobial resistance.
