ClearColonization 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.
Antimicrobial Activities of Vernonia Amygdalina Against Biofilm-forming Microbes
This study evaluated antimicrobial properties of Vernonia amygdalina plant extracts against biofilm-forming bacteria, testing the extract's effectiveness as a natural alternative to conventional antibiotics. (Note: this paper does not appear to be directly focused on microplastics research.)
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.
Metal leaching from plastics in the marine environment: An ignored role of biofilm.
Researchers investigated how biofilms on marine plastics influence metal leaching, finding that microbial colonization significantly alters the release rates of metal additives from common polymers, representing a previously underappreciated pathway for heavy metal transfer from plastic debris into marine ecosystems.
Ecotoxicological and health implications of microplastic-associated biofilms: a recent review and prospect for turning the hazards into benefits
This review examined the ecological and health implications of biofilms that form on microplastics, discussing how these plastisphere communities can harbor pathogens and alter microplastic properties, while also exploring potential beneficial applications of microplastic-associated biofilms.
Biofilm on microplastics in aqueous environment: Physicochemical properties and environmental implications
This review examines how bacteria and other microorganisms form sticky films called biofilms on microplastic surfaces in water. These biofilms change how microplastics move through the environment and increase their ability to absorb pollutants like heavy metals, pesticides, and antibiotics. Biofilm-coated microplastics may also carry harmful bacteria, making them a greater potential health risk than clean microplastic particles.
[Applications of biofilm in environmental pollution control and the related challenges].
This review examines biofilm structure, formation mechanisms, and community composition as applied to environmental pollution control, covering removal of heavy metals and organic pollutants, and discussing emerging challenges including plastisphere dynamics, antibiotic resistance gene spread, and pathogen accumulation in biofilm-pollutant interactions.
Strategies for biofilm optimization of plastic-degrading microorganisms and isolating biofilm formers from plastic-contaminated environments
This study investigated biofilm formation as a prerequisite for microbial plastic degradation, both optimizing biofilm formation in known plastic degraders and isolating novel biofilm formers from plastic-contaminated environments. Strategies to enhance surface colonization were evaluated as a practical step toward improving plastic biodegradation efficiency.
The effects of metals and polymer types on the development of biofilm on microplastic surface
Researchers examined biofilm development on three polymer types (PVC, polystyrene, and polyethylene) in the presence of three heavy metals (lead, chromium, and cadmium) to determine how metal contamination influences the formation and composition of plastisphere communities. The study assessed whether metal-microplastic co-contamination alters the structure of microbial biofilms that colonize plastic surfaces in aquatic environments.
Biofilm formation and its implications on the properties and fate of microplastics in aquatic environments: A review
Researchers reviewed how microplastics in water attract and support communities of bacteria and other microorganisms that form biofilms — living coatings that alter the plastic particles' movement, help them carry pathogens, and affect how toxic chemicals attached to the plastic are absorbed by living things. Understanding this "plastisphere" ecosystem is critical for predicting where microplastics go and how harmful they become.
Do microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes and their associations with bacterial communities under antibiotic and metal pressures?
Researchers investigated whether microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes compared to natural substrates, examining how combined antibiotic and metal pressures shape resistant bacterial communities on plastic surfaces.
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.
Biofilm Structural and Functional Features on Microplastic Surfaces in Greenhouse Agricultural Soil
Researchers studied biofilm formation on five types of microplastics in greenhouse agricultural soil over 30 days at two concentrations. The study found evidence of microbial enrichment on all plastic types, with biofilm community composition varying by polymer type and concentration. The findings suggest that microplastics in agricultural soils serve as distinct microbial habitats that may influence soil microbial ecology.
The role of microplastics biofilm in accumulation of trace metals in aquatic environments
This review examines how biofilms that form on microplastics in aquatic environments enhance the accumulation of trace metals from surrounding water. Researchers found that microorganisms colonizing plastic surfaces produce extracellular substances that facilitate metal sorption, effectively turning microplastics into concentrated carriers of metallic contaminants. The study highlights the dual pollution risk posed by microplastics serving as both physical pollutants and vehicles for toxic metal transport in waterways.
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.
Biofilm Formation of Clinically Important Bacteria on Bio-Based and Conventional Micro/Submicron-Sized Plastics.
This study compared how clinically important bacteria form biofilms on bio-based versus conventional plastic surfaces of similar size, finding differences in biofilm formation patterns between bioplastics and their conventional equivalents. The results suggest that the push to replace conventional plastics with bioplastics should consider how these materials interact with potentially harmful bacteria.
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.
