ClearDynamics and implications of biofilm formation and community succession on floating marine plastic debris
Researchers examined how biofilms form on plastic debris in aquatic environments and how the resulting microbial communities evolve over time, finding that the plastisphere hosts distinct microbial assemblages including potential pathogens. The study has implications for understanding plastic debris as a vector for microbial dispersal.
The ecology of the plastisphere: Microbial composition, function, assembly, and network in the freshwater and seawater ecosystems
Researchers studied the communities of bacteria and fungi that colonize microplastic surfaces in freshwater and seawater, forming what scientists call the plastisphere. These microplastic-associated communities were distinctly different from those in surrounding water, and included a higher proportion of disease-causing organisms and species involved in pollutant degradation. The findings suggest that microplastics create new habitats that can harbor pathogens and alter natural microbial ecosystems in ways that may affect water quality and human health.
The structure and assembly mechanisms of plastisphere microbial community in natural marine environment
Researchers investigated how microbial communities colonize different types of microplastic surfaces in natural marine environments over an eight-week period. They found that the composition of these plastic-associated microbial communities, known as the plastisphere, was shaped more by environmental conditions and time than by the specific type of plastic. The study provides new understanding of the ecological processes governing how microorganisms assemble on ocean plastic debris.
Distinct microbial communities in the microplastisphere of inland wetlands: Diversity, composition, co-occurrence networks, and functions.
Researchers collected samples from different inland wetland types to characterize the microbial communities colonizing plastic surfaces (the microplastisphere), finding distinct bacterial and fungal communities compared to surrounding soils. Community composition varied by wetland type and plastic surface, highlighting the ecological diversity of plastic-associated microbiomes in freshwater habitats.
The plastisphere ecology: Assessing the impact of different pollution sources on microbial community composition, function and assembly in aquatic ecosystems
Researchers studied the microbial communities living on microplastic surfaces (called the plastisphere) across four different aquatic sites and found that plastics host a distinctly different mix of microbes than the surrounding water, shaped by local pollution sources. These plastic-surface microbes also carry more antibiotic resistance genes and show greater potential for breaking down plastics, making the plastisphere both a health concern and a potential bioremediation resource.
ОСОБЕННОСТИ ПОВЕДЕНИЯ МИКРОПЛАТИКА В ВОДНОЙ СРЕДЕ: ПЛАСТИСФЕРА - НОВАЯ МОРСКАЯ ЭКОСИСТЕМА
This review examines the behavior of microplastics in aquatic environments with a focus on the Plastisphere - microbial communities colonizing plastic surfaces that form a novel marine ecosystem. The review synthesizes information on Plastisphere formation mechanisms, distribution in water, risks associated with pathogen and pollutant transport, and potential applications for removing microplastics from contaminated water.
Comparison between discarded facemask and common plastic waste on microbial colonization and physiochemical properties during aging in seawater
Researchers found that discarded surgical facemasks in seawater hosted more diverse microbial communities than conventional plastic waste, with higher degradation-related enzyme activity and more pronounced physicochemical changes during aging, raising concerns about their environmental impact.
Bacterial pathogens associated with the plastisphere of surgical face masks and their dispersion potential in the coastal marine environment
Researchers deployed face masks in coastal seawater for two months and used advanced DNA sequencing to identify bacterial pathogens colonizing the plastic surfaces. The study found that face masks selectively enriched certain putative pathogens rarely found in surrounding seawater and released considerable microfibers during degradation, suggesting that pandemic-related mask waste in oceans may serve as vectors for transporting harmful bacteria across marine environments.
Plastisphere microbiome: Methodology, diversity, and functionality
This review explores the plastisphere, the community of microorganisms that colonize plastic debris in the environment. The authors cover methods for studying these microbial communities, the diversity of organisms found living on plastics, and their functional roles including potential plastic degradation and pathogen harboring. Understanding the plastisphere is important because these microbial communities can influence how plastics break down and what health risks plastic pollution may pose.

Dynamics and functions of microbial communities in the plastisphere in temperate coastal environments
Researchers explored microbial communities colonizing microplastics in coastal environments of Japan, comparing bacterial and fungal communities across different plastic types, water, sediment, and sand. The study found that while microbial communities varied by sample type and location rather than plastic shape, microplastics harbored hydrocarbon-degrading organisms as well as potential pathogens, highlighting the ecological significance of plastic-associated biofilms.
Plastisphere - a new habitat of microbial community: Composition, structure and ecological consequences
This review examines the plastisphere — microbial communities colonizing microplastics — covering the composition and structure of plastisphere microbiomes across marine, freshwater, and terrestrial environments and discussing ecological consequences including pathogen dispersal.
Effects of Discarded Masks on the Offshore Microorganisms during the COVID-19 Pandemic
Discarded COVID-19 masks released microplastics into seawater, and researchers profiled how these particles interact with offshore marine microorganisms. The microplastics altered microbial community composition and affected biofilm formation on the plastic surfaces. These findings highlight pandemic-related plastic waste as a source of microplastic pollution that disrupts marine microbial ecosystems.
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.
From rivers to marine environments: A constantly evolving microbial community within the plastisphere
Researchers sampled 107 plastic pieces across four aquatic ecosystems in southern France and found that the sampling location and polymer chemistry were the strongest drivers of plastisphere microbial community composition, while only 11% of samples showed elevated Vibrio pathogen levels compared to surrounding water.

[Community Structure and Microbial Function Responses of Biofilms Colonizing on Microplastics with Vertical Distribution in Urban Water].
Biofilm communities colonizing microplastics at different depths in urban water bodies were found to differ significantly in community structure and metabolic function. Microplastics at different depths were exposed to varying light, oxygen, and nutrient conditions, which shaped the attached microbial communities. Understanding how microplastics host distinct microbial assemblages is important for assessing their role as vectors for pathogens and chemical pollutants.
Effects of Biofouling on the Properties and Sinking Behavior of Disposable Face Masks in Seawater: A Systematic Comparison with Microplastic Films and Particles
A 16-week seawater incubation showed that disposable face masks accumulated biofilm at roughly ten times the rate of microplastic films or particles, causing the masks to eventually sink rather than float at the surface. This demonstrates that mask-derived microplastic fibers are rapidly transferred to the seafloor, where their ecological impacts and persistence may be far greater than previously assumed.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
