ClearMicrobial Diversity of the Surface of Polypropylene and Low Density Polyethylene‐Based Materials (Plastisphere) From an Area Subjected to Intensive Agriculture
Researchers analyzed the microbial communities colonizing polypropylene and polyethylene plastic debris from an agricultural landfill site. They found that while overall bacterial diversity was similar between plastic surfaces and surrounding soil, the plastic-associated communities had distinct compositions with higher proportions of certain bacterial groups. The study suggests that these plastisphere communities may be actively degrading plastic additives and could harbor potential plastic-degrading organisms.

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.

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.
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.

This review examines the microorganisms and enzymes capable of degrading polyethylene and discusses how combining genomic tools with studies of plastic-associated microbial communities could lead to more effective biodegradation strategies. The findings suggest that engineered microbial consortia guided by omics data hold promise for breaking down one of the world's most persistent plastics.
