ClearNew 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.
Structural Diversity in Early-Stage Biofilm Formation on Microplastics Depends on Environmental Medium and Polymer Properties
This study examined the early stages of bacterial biofilm formation on different types of plastic surfaces in different environmental media, finding that both the growth medium and the polymer type influenced which microbial communities colonized the plastic. These plastic-associated biofilms (the plastisphere) can make microplastics more appealing to filter-feeding organisms that mistake them for food.
Microplastic biofilm in fresh- and wastewater as a function of microparticle type and size class
Researchers compared the biofilm communities that form on microplastics of different types and sizes in both freshwater and wastewater, finding that biofilm composition was influenced by particle type, size, and water source. These findings advance understanding of the plastisphere — the microbial community unique to plastic surfaces — and its potential role in spreading microorganism-associated risks.
Genomic and proteomic profiles of biofilms on microplastics are decoupled from artificial surface properties
Genomic and proteomic analysis of biofilms on marine microplastics showed that community composition and functional profiles were primarily shaped by environmental conditions rather than the specific surface properties of the plastic substrate.
Plastics select for distinct early colonizing microbial populations with reproducible traits across environmental gradients
Incubation of virgin microplastics across oceanic transects showed early colonization was reproducibly dominated by Alteromonadaceae with enriched genes for adhesion, biofilm formation, and hydrocarbon degradation, while mature plastic biofilms shifted to Rhodobacteraceae with genes for carbohydrate hydrolysis and photosynthesis.
Structural and Functional Characteristics of Microplastic Associated Biofilms in Response to Temporal Dynamics and Polymer Types
Researchers found that biofilm structural and functional characteristics on microplastics differ significantly depending on polymer type (polyethylene, polypropylene, and polystyrene) and change over time, with implications for understanding microbial colonization and the plastisphere.
Size-dependent effects of microplastics on antibiotic resistance genes fate in wastewater treatment systems: The role of changed surface property and microbial assemblages in a continuous exposure mode
Researchers developed a continuous exposure method to evaluate how different sizes of microplastics affect antibiotic resistance gene fate in wastewater treatment, finding that smaller microplastics had greater impacts on microbial communities and resistance gene proliferation.
Time-series incubations in a coastal environment illuminates the importance of early colonizers and the complexity of bacterial biofilm dynamics on marine plastics
Researchers used time-series incubations in a coastal marine environment to track plastisphere biofilm formation on microplastics, finding that early bacterial colonizers play a disproportionate role in shaping community dynamics and that biofilm composition is highly complex, varying with polymer type, incubation time, and surrounding environment.
Role of Microplastics as Attachment Media for the Growth of Microorganisms
Researchers reviewed how microplastics serve as attachment media for microbial growth, finding that biofilms forming on microplastic surfaces create unique microbial communities — including potential pathogens — that differ from those in surrounding environments.
Environmental Factors Support the Formation of Specific Bacterial Assemblages on Microplastics
Researchers incubated polystyrene, polyethylene, and wooden pellets across marine and freshwater environments and found that environmental conditions — more than plastic type — drove the formation of specific bacterial communities on microplastics, with plastic-specific assemblages only emerging under certain conditions.
Characteristics of Initial Attachment and Biofilm Formation of Pseudomonas aeruginosa on Microplastic Surfaces
Researchers characterized how Pseudomonas aeruginosa initially attaches to and forms biofilms on different microplastic surfaces, finding that polymer type and surface properties significantly influenced bacterial colonization patterns and biofilm development.
Unique Bacterial Community of the Biofilm on Microplastics in Coastal Water
Researchers compared bacterial communities forming biofilms on steel, silica, and PVC microplastic surfaces in coastal seawater and found that biofilm composition differed by material type. This shows that the type of plastic surface influences which microbial communities colonize it, with implications for how microplastics may spread specific bacteria.
Colonization characteristics and surface effects of microplastic biofilms: Implications for environmental behavior of typical pollutants
This review examines how bacteria colonize microplastic surfaces in water, forming biofilms that change how the plastics behave in the environment. These biofilms alter the surface properties of microplastics and affect how they absorb and transport heavy metals and other pollutants. Understanding biofilm formation on microplastics is important because it can make the particles more dangerous by concentrating toxic substances that could eventually enter the food chain.

Lacustrine plastisphere: Distinct succession and assembly processes of prokaryotic and eukaryotic communities and role of site, time, and polymer types
Researchers investigated how microbial communities colonize different types of microplastic polymers in freshwater lakes. The study found that bacteria and single-celled organisms follow distinct assembly patterns on microplastic surfaces, with colonization time, location, and polymer type all influencing community composition. These findings suggest microplastics serve as carriers that can promote microbial spread in aquatic environments.

Researchers analyzed microbial biofilm communities on microplastic surfaces in both marine and freshwater environments, finding that plastic-associated biofilms harbor distinct prokaryotic and eukaryotic communities with potential roles in plastic biodegradation.
Investigating Biofilms: Advanced Methods for Comprehending Microbial Behavior and Antibiotic Resistance
This review summarizes recent advances in biofilm research, focusing on how communities of microorganisms form protective layers on surfaces and become resistant to antibiotics. The sticky matrix that holds biofilms together plays a key role in spreading antibiotic resistance genes between bacteria. While not directly about microplastics, the findings are relevant because microplastics in the environment serve as surfaces where these resistant biofilms can form and spread.
Microplastic bacterial communities in the Bay of Brest: Influence of polymer type and size
Researchers analyzed bacterial communities growing on microplastics collected from a coastal bay in France and found that the type of polymer influenced which bacteria colonized the surface. Different plastics like polyethylene, polypropylene, and polystyrene each hosted distinct microbial communities, though particle size had less influence. The study reveals that microplastics in the ocean serve as unique habitats for bacteria, which could have implications for how pollutants and pathogens are transported through marine environments.
The Importance of Biofilms to the Fate and Effects of Microplastics
This review examines how biofilms — communities of microorganisms that form on microplastic surfaces — affect the fate and ecological effects of plastic pollution. Biofilm formation alters how microplastics are transported, ingested, and degraded in the environment, and the plastisphere can harbor pathogens and antibiotic-resistant bacteria that may pose risks to human health.
