This is a dataset accompanying a study on antibiotic-resistant bacteria in biofilms growing on microplastics in wastewater treatment plant effluents. The data include DNA sequencing results showing which bacterial species colonize plastic surfaces in treated wastewater.
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.
Early and differential bacterial colonization on microplastics deployed into the effluents of wastewater treatment plants
Researchers deployed seven types of microplastic materials into the effluents of two wastewater treatment plants and characterised bacterial communities colonising them after an early biofilm formation period using 16S rRNA sequencing. They found significantly higher bacterial diversity on microplastics than in the surrounding free-living water, and detected elevated antibiotic resistance genes (sulI, tetM) on microplastic surfaces, suggesting that WWTP effluents seed microplastics with pathogen- and resistance gene-carrying biofilms.
The factors affecting bacterial colonisation on microplastics and the impact of tertiary treatment of wastewater on the attached bacteria and microplastics
This study examined the factors that influence bacterial colonization on microplastics and tested how tertiary wastewater treatment affects the bacteria and microplastics discharged from a treatment plant. Microplastic-associated biofilms in wastewater can carry harmful and antibiotic-resistant bacteria into receiving water bodies.
Microplastic biofilm, associated pathogen and antimicrobial resistance dynamics through a wastewater treatment process incorporating a constructed wetland
This study tracked how microplastic-associated biofilms, pathogens, and antibiotic resistance genes changed through a wastewater treatment process that included a constructed wetland. While the treatment reduced some pathogens, certain antibiotic resistance genes persisted on microplastic surfaces even after treatment. This means microplastics leaving treatment plants could carry drug-resistant bacteria into rivers and lakes, potentially affecting downstream drinking water sources.
Assessment of Emerging Pathogens and Antibiotic Resistance Genes in the Biofilm of Microplastics Incubated Under a Wastewater Discharge Simulation
Researchers incubated common plastic types in flowing water that simulated wastewater discharge conditions for 10 weeks and studied the bacteria that colonized the plastic surfaces. They found that microplastics exposed to treated wastewater developed distinct bacterial communities compared to those in clean river water, including emerging pathogens and antibiotic resistance genes. The study suggests that microplastics in waterways receiving wastewater may serve as mobile platforms for spreading harmful bacteria and antibiotic resistance in the environment.
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.
Contribution of microplastic particles to the spread of resistances and pathogenic bacteria in treated wastewaters
Researchers studied microplastic particles collected from treated wastewater effluents and found that MPs harbored significantly higher loads of antibiotic resistance genes and pathogenic bacteria compared to surrounding water, suggesting MPs facilitate their environmental spread.
Microplastics in fresh- and wastewater are potential contributors to antibiotic resistance - A minireview
Researchers reviewed the link between microplastic pollution and the spread of antibiotic resistance in freshwater environments, finding that microplastic surfaces host unique bacterial communities enriched in antibiotic-resistant bacteria and the resistance genes they can share with other microbes. The close packing of bacteria in these plastic-surface biofilms may accelerate the spread of drug-resistant pathogens through drinking water sources, though the full health implications remain poorly understood.
The dangerous transporters: A study of microplastic-associated bacteria passing through municipal wastewater treatment
This study characterized bacterial communities attached to microplastics sampled from multiple stages of a municipal wastewater treatment plant, finding that diverse bacteria including potential pathogens and antibiotic-resistant strains remained attached to microplastics through all treatment steps. The results suggest microplastics could transport hazardous bacteria through wastewater treatment and into receiving environments.
Impact of wastewater treatment plant effluent discharge on the antibiotic resistome in downstream aquatic environments: a mini review
This review summarizes how wastewater treatment plants release antibiotic-resistant bacteria and resistance genes into rivers and lakes through their treated water. Current treatment processes cannot fully remove these resistance factors, allowing them to spread in downstream water bodies and potentially reach humans through drinking water and the food chain. The review is relevant to microplastics research because microplastics in wastewater can serve as surfaces where resistant bacteria grow and spread.
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.
Identification of microplastic-associated microbial communities from various stages of wastewater treatment and recipient surface waters using MALDI-TOF mass spectrometry
Researchers deployed six polymer types at different stages of wastewater treatment across three Hungarian plants and used MALDI-TOF mass spectrometry to identify the bacteria colonizing microplastic surfaces, finding distinct microbial communities that may act as vectors for antibiotic resistance.
Antibiotic-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.
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.
Antibiotic resistance genes and virulence factors in the plastisphere in wastewater treatment plant effluent: Health risk quantification and driving mechanism interpretation
Researchers found that microplastics in treated wastewater carry significantly more disease-causing bacteria, antibiotic resistance genes, and virulence factors on their surfaces compared to the surrounding water. This means microplastics released from wastewater treatment plants into rivers and lakes could spread antibiotic-resistant infections, posing a direct risk to communities that rely on these water sources.
Microplastic biofilms in water treatment systems: Fate and risks of pathogenic bacteria, antibiotic-resistant bacteria, and antibiotic resistance genes
This review examines how microplastics in drinking water and wastewater treatment plants develop biofilms that harbor dangerous bacteria and antibiotic resistance genes. The biofilm-coated microplastics can protect pathogens from disinfection processes, allowing them to survive treatment and potentially reach tap water. This raises concerns about microplastics serving as vehicles for antibiotic-resistant bacteria in our water supply.
Biofilm formation on microplastics in wastewater: insights into factors, diversity and inactivation strategies
This study investigated how bacteria form biofilms on different types of microplastics in wastewater, finding that polyethylene supported the most biofilm growth, especially in dark, warm, oxygen-rich conditions. The biofilms contained bacteria from groups that include potential human pathogens, and different plastic types supported different microbial communities. This matters because microplastics coated in bacterial biofilms could transport harmful microorganisms through water systems and into the environment.
Plastisphere showing unique microbiome and resistome different from activated sludge
Researchers used metagenomics to compare the microbiome and resistome of PVC plastisphere biofilms with activated sludge, finding that microplastic surfaces enriched distinct pathogenic bacteria and antibiotic resistance genes that differ from the surrounding sludge community.
Fates of extracellular and intracellular antibiotic resistance genes in activated sludge and plastisphere under sulfadiazine pressure
Researchers found that microplastics in wastewater treatment systems act as reservoirs for antibiotic resistance genes, with the plastic surfaces (plastisphere) harboring more resistance genes than the surrounding sludge. When exposed to the antibiotic sulfadiazine, the spread of resistance genes on microplastic surfaces increased, and DNA from potential pathogens was detected. This suggests that microplastics leaving wastewater treatment plants could carry drug-resistant bacteria into waterways, posing a risk to public health.
