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.
Selective enrichment of bacterial pathogens by microplastic biofilm
Researchers incubated biofilms on microplastics and natural substrates in freshwater and found that microplastic surfaces selectively enriched bacterial pathogens and antibiotic resistance genes compared to rock and leaf surfaces. The study suggests that microplastics in waterways may serve as hotspots for harmful bacteria and contribute to the spread of antibiotic resistance in the environment.
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.
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.
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.
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.

Researchers developed a laboratory flow-through system to study how biofilms grow on microplastics under controlled freshwater conditions. They found that biofilm formation varied depending on the polymer type, water temperature, and nutrient levels, with warmer and more nutrient-rich conditions promoting faster colonization. The study provides a standardized method for assessing how microplastics in freshwater systems become platforms for microbial communities that could include harmful organisms.
Biofilm formation on polyethylene microplastics and their role as transfer vector of emerging organic pollutants
This study examined how bacteria form biofilms on polyethylene microplastics and whether those biofilms help transport organic pollutants like common pharmaceuticals and pesticides. Researchers found that the bacterium Pseudomonas aeruginosa readily colonized microplastics, and the presence of contaminants in the water altered biofilm characteristics. The findings suggest that microplastics in waterways may act as carriers that help spread pharmaceutical and chemical pollutants through aquatic environments.

This review examines how biofilms — communities of microorganisms that form on microplastic surfaces — affect the fate and ecological effects of plastic pollution.
