ClearStructural 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.
Comparative Analysis of Selective Bacterial Colonization by Polyethylene and Polyethylene Terephthalate Microplastics
Biofilm communities were compared on polyethylene and polyethylene terephthalate microplastics incubated in two freshwater bacterial communities, finding that the original water source bacteria largely determined biofilm composition rather than the plastic type. The study suggests that the plastisphere in freshwater systems reflects local microbial pools more than plastic-specific selection.
Microbiological Characterization of the Biofilms Colonizing Bioplastics in Natural Marine Conditions: A Comparison between PHBV and PLA
Researchers characterized biofilm communities colonizing bioplastics and conventional plastics in natural marine conditions, finding that bioplastic surfaces hosted distinct microbial communities compared to petroleum-based plastics, with implications for biodegradation and ecological interactions.
Distinct community structure and microbial functions of biofilms colonizing microplastics
Biofilm communities were established on polyethylene, polypropylene, cobblestone, and wood substrates over 21 days under controlled conditions and compared by 16S rRNA sequencing, finding that plastic substrates harbored distinct microbial communities and functional profiles compared to natural materials. The study demonstrates that microplastics in freshwater environments provide a selective niche that enriches for distinct microbial taxa and metabolic functions.
Microbial biofilm formation and community structure on low-density polyethylene microparticles in lake water microcosms
Researchers investigated biofilm formation on low-density polyethylene microparticles in lake water microcosms, finding that microplastic surfaces supported distinct and dynamic microbial communities that differed from those in the surrounding water.
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.
Diversity and structure of microbial biofilms on microplastics in riverine waters of the Pearl River Delta, China
Microbial biofilm communities on microplastics in Pearl River Delta waterways showed distinct composition and diversity compared to surrounding water and natural surfaces, with river environmental conditions more influential than plastic polymer type in shaping biofilm structure.
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.
Microalgae colonization of different microplastic polymers in experimental mesocosms across an environmental gradient
Microalgal colonization of five different microplastic polymer types was monitored in freshwater mesocosms across an environmental gradient, finding that polymer type, surface properties, and environmental conditions all influenced the biomass and community composition of epiplastic microalgal biofilms.
Characterization of Microplastic-Associated Biofilm Development along a Freshwater-Estuarine Gradient
Researchers characterized biofilm bacterial communities on three types of microplastics incubated along a freshwater-estuarine gradient, finding that salinity and plastic type influenced microbial community composition and succession over a 31-day period.
Microplastic-Associated Biofilms: A Comparison of Freshwater and Marine Environments
This review compared microplastic-associated biofilm communities in freshwater and marine environments, examining how plastic type, ecosystem, and environmental conditions shape the microbial communities that colonize plastic surfaces. Understanding these "plastisphere" communities is important because they may include pathogens and can affect the fate and transport of plastic particles.
The composition of bacterial communities associated with plastic biofilms differs between different polymers and stages of biofilm succession
Researchers tracked bacterial community development on five different plastic types submerged in coastal waters over two months. They found that bacterial community composition varied by both plastic type and stage of colonization, with distinct early and late succession patterns. The study provides evidence that different plastics may host different microbial communities, which has implications for understanding how plastic pollution influences marine microbial ecology.
Distinctive patterns of bacterial community succession in the riverine micro-plastisphere in view of biofilm development and ecological niches
Scientists studied how bacterial communities develop on microplastics versus natural materials in river water and found that plastics support a distinct pattern of microbial colonization. The research identified specific bacteria capable of degrading microplastics and revealed that competition among microbes on plastic surfaces follows unexpected patterns compared to natural substrates.

Unraveling Microplastic-Biofilm Nexus in Aquaculture: Diversity and Functionality of Microbial Communities and Their Effect on Plastic Traits
Researchers incubated five common types of microplastics in an aquaculture pond for 128 days and found that biofilm formation varied significantly depending on the plastic type, with polypropylene and polyethylene supporting the richest microbial communities. PET microplastics attracted more plastic-degrading bacteria like Pseudomonas, while all plastic types enriched potentially pathogenic microorganisms. The findings highlight how different microplastics selectively shape microbial colonization in aquaculture environments, with implications for both environmental health and food safety.
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.
