ClearDiscovering untapped microbial communities through metagenomics for microplastic remediation: recent advances, challenges, and way forward
This review explores how metagenomic approaches are uncovering microbial communities capable of degrading microplastics in various environments. Researchers found that diverse bacteria and fungi in soil, water, and waste systems produce enzymes that can break down plastic polymers, though degradation rates remain slow. The study highlights metagenomics as a powerful tool for discovering new biological solutions to microplastic pollution.
Microplastics in the marine environment : an ecotoxicological perspective
This doctoral thesis studied the ecotoxicology of marine plastic pollution, examining how microplastics and plastic-associated chemicals affect microbial communities, algae, and invertebrates. The work found that the plasticizer microbiome — bacteria colonizing plastic surfaces — differs from surrounding seawater and may influence how plastic-associated pollutants move through food webs.
Analysis of 16S rRNA amplicon data illuminates the major role of environment in determining the marine plastisphere microbial communities
Researchers analysed 16S rRNA amplicon data from marine plastisphere communities, finding that environmental factors play the dominant role in determining the microbial communities that colonise microplastic surfaces in marine ecosystems.
Microplastic biofilms as potential hotspots for plastic biodegradation and nitrogen cycling: a metagenomic perspective
Researchers used genetic analysis to study the microbial communities that form biofilms on different types of microplastics in an estuarine environment. They found that these plastic-associated communities contained genes for both plastic degradation and nitrogen cycling, suggesting the biofilms may play dual roles in the ecosystem. The study indicates that microplastic surfaces in waterways create unique microbial habitats that could influence both pollution breakdown and nutrient processing.
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.
Exploring the Composition and Functions of Plastic Microbiome Using Whole-Genome Sequencing
Whole-genome sequencing of microbial biofilms on four types of marine microplastics revealed that plastic surfaces harbor distinct microbial communities with unique functional potential, including enrichment of Vibrio species with pathogenic and plastic-degrading capabilities.
Shotgun Metagenomic insights into the Plastisphere microbiome: Unveiling potential for clinical and industrial enzymes production along with plastic degradation
Researchers used shotgun metagenomic sequencing to analyze microbial communities (plastisphere) colonizing plastic debris in soil and aquatic environments, finding that 54% of bacteria had plastic-degrading potential and that the plastisphere also harbored clinically relevant and industrially useful enzymes. The findings suggest the plastisphere is a reservoir of both plastic-degrading and biotechnologically valuable microorganisms.
[Interaction between microplastics and microorganisms in soil environment: a review].
This review examines how microplastics alter soil microbial community structure and diversity, and how microorganisms in turn colonize plastic surfaces and degrade them through extracellular enzymes — with degradation efficiency dependent on polymer properties and environmental conditions.
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.
Review of microplastic degradation: Understanding metagenomic approaches for microplastic degrading organisms
This review explores how metagenomics, the study of genetic material from environmental samples, is helping scientists identify microorganisms that can break down plastics. The paper covers the methods used to find and characterize plastic-degrading bacteria, as well as the environmental consequences of plastic degradation including health risks from inhaling and ingesting microplastics. While biological solutions to plastic pollution show promise, the review notes that more research is needed to develop effective, scalable approaches.

Researchers isolated and characterized microbial communities from microplastic-polluted soil, identifying bacteria capable of colonizing plastic surfaces and assessing their potential roles in plastic degradation and soil nutrient cycling.
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.

This review synthesizes research on biofilm communities forming on marine microplastics, covering their composition, formation dynamics, and potential consequences for both plastic fate and ocean microbiology.

Exploring untapped bacterial communities and potential polypropylene-degrading enzymes from mangrove sediment through metagenomics analysis
Researchers used metagenomics analysis to explore bacterial communities in mangrove sediments that may be capable of breaking down polypropylene plastic. The study compared microbial communities exposed to virgin and chemically pretreated polypropylene over several months. Evidence indicates that certain bacterial taxa in mangrove environments possess enzymes with potential polypropylene-degrading activity, suggesting possible biological pathways for plastic waste remediation.
Metatranscriptomics of microbial biofilm succession on HDPE foil: uncovering plastic-degrading potential in soil communities
Using genetic analysis, researchers examined which microbial genes are active on polyethylene plastic surfaces in landfill soil versus undisturbed forest soil. They found that both communities carry genes capable of degrading plastic, with plastic-degrading enzymes being most active during early biofilm formation. The discovery that even undisturbed soils harbor plastic-degrading microbes is promising for bioremediation strategies, though the slow rate of natural breakdown means microplastics still persist in soils for very long periods.
Novel functional insights into the microbiome inhabiting marine plastic debris: critical considerations to counteract the challenges of thin biofilms using multi-omics and comparative metaproteomics
