ClearBacterial Abundance, Diversity and Activity During Long-Term Colonization of Non-biodegradable and Biodegradable Plastics in Seawater
Biofilm communities on conventional (polyethylene and polystyrene) and biodegradable plastics were tracked over 7 months of seawater immersion, finding highly abundant and diverse plastisphere communities on all polymer types but limited evidence of active plastic biodegradation under natural marine conditions.
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.
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.
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.
A review on microbial-biofilm mediated mechanisms in marine microplastics degradation
This review examines how microbial biofilms form on microplastics in marine environments and their potential role in degrading these persistent pollutants. Researchers found that plastic-associated biofilm communities are diverse and influenced by factors such as polymer type, particle size, and seasonal conditions. The study identifies knowledge gaps in understanding how bacterial and fungal communities on microplastics may contribute to their breakdown in ocean environments.
Biodegradable plastics in Mediterranean coastal environments feature contrasting microbial succession
Researchers incubated biodegradable and conventional plastics in three Mediterranean coastal environments for 22 months and found that the surrounding habitat — not the plastic type — primarily shaped which microbes colonized the surface. Despite some putative plastic-degrading bacteria being present, there was no consistent community of microbes clearly linked to biodegradable plastic breakdown in natural marine settings.
Large-scale omics dataset of polymer degradation provides robust interpretation for microbial niche and succession on different plastisphere
Researchers generated a large-scale microbiome and metabolome dataset from five biodegradable polymer types, revealing that microbial communities converge to polymer-specific compositions during degradation and follow distinct succession stages from initial colonization through biofilm formation.
Biofilm development as a factor driving the degradation of plasticised marine microplastics
Researchers investigated how natural marine biofilms drive the degradation of plasticized microplastics. The study found that biodegradation was dependent on polymer type, plasticizer type, and time, with polystyrene containing bisphenol A showing the most degradation, coinciding with increased abundance of putative biodegradative bacteria in the colonizing biofilm.
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.
Investigating the roles of microbes in biodegrading or colonizing microplastic surfaces
Researchers investigated the roles of microbes in biodegrading or colonizing microplastic surfaces, examining how microbial communities interact with plastic polymers in environmental settings. The study characterized the 'plastisphere' — the community of microorganisms that colonize microplastic surfaces — and assessed the extent to which microbial activity contributes to plastic degradation in natural environments.
Microbial Colonization in Marine Environments: Overview of Current Knowledge and Emerging Research Topics
This review examines how microorganisms colonize submerged surfaces in aquatic environments, with a focus on the factors shaping biofilm communities on microplastics. The authors discuss how the chemical and physical properties of plastic surfaces influence microbial attachment and community development compared to natural substrates.
Microbial colonization and succession on polylactic acid microplastics (PLA MPs) in mangrove forests - the role of environmental conditions and plastic properties
Researchers incubated two types of biodegradable polylactic acid microplastics in mangrove ecosystems across four environmental settings for 90 days to study microbial colonization patterns. They found that microbial colonization progressed more rapidly in sediment than in water, and the type of plastic influenced which microbial communities developed. The study suggests that environmental conditions and plastic properties together shape how microorganisms interact with biodegradable plastics in natural settings.
Evaluation of prokaryotic and eukaryotic microbial communities on microplastic‐associated biofilms in marine and freshwater 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.
Spatial and seasonal variation in diversity and structure of microbial biofilms on marine plastics in Northern European waters
Researchers investigated how microbial biofilm communities on marine plastics vary by season, location, and plastic type in Northern European waters. The study found distinct spatial and seasonal patterns in plastisphere microbial communities on polyethylene terephthalate surfaces, providing insights into how plastic debris develops unique biological communities in marine environments.
Marine biodegradation mechanism of biodegradable plastics revealed by plastisphere analysis
Researchers analyzed the marine biodegradation mechanisms of two biodegradable plastics, PHBV and PBSA, by examining plastisphere functional gene assemblages, finding that differences in microbial community composition on their surfaces help explain why these polyesters degrade at substantially different rates in seawater.
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.
Role of Biofilms in the Degradation of Microplastics
This review examines the role of microbial biofilms in degrading microplastics, presenting insights into how microbial communities colonizing plastic surfaces may contribute to the breakdown of microplastic particles in aquatic and terrestrial environments.
Early stage biofilm formation on bio-based microplastics in a freshwater reservoir
