ClearA Comparative Study of Low-density Polyethylene Shopping Carry Bag Degrading Bacteria Isolated from Marine and Garden Soil
Researchers isolated bacteria from marine and garden soil and tested their ability to degrade low-density polyethylene (LDPE) plastic bags. Two species — Paenibacillus castanea and Riemerella anatipestifer — achieved up to 7.3% weight loss of LDPE after 35 days, demonstrating that soil bacteria can slowly break down this common plastic. This research is relevant to understanding natural LDPE degradation pathways and the formation of microplastics as larger plastic items fragment in soil and marine environments.
Biodegradation of LDPE plastic by local strain of Bacillus sp. isolated from dump soil of Pekanbaru, Indonesia
Scientists isolated a local strain of Bacillus bacteria from landfill soil in Indonesia and tested its ability to break down low-density polyethylene (LDPE) plastic. The bacteria showed measurable ability to degrade LDPE, reducing plastic weight over time. This research supports the potential for using locally sourced soil bacteria in plastic biodegradation efforts.
Microorganism-Based Bioremediation Approach for Plastics and Microplastics Wastes

Biodegradation of Low Density Polyethylene (LDPE) using marine bacteria isolated from tropical beaches of megacity Mumbai
Marine bacteria isolated from plastic debris buried in beach sediments at seven Mumbai beaches were able to colonize and partially degrade low-density polyethylene (LDPE) plastic. Identifying bacteria naturally adapted to plastic-rich marine environments is a step toward developing biological tools for plastic degradation, though the process is currently far too slow to address the scale of ocean plastic pollution without significant enhancement.
Introducing the LDPE degrading microbes of sedimentary systems: from dumpsite to laboratory
This study identified and characterized low-density polyethylene (LDPE)-degrading microbes from dumpsite sedimentary systems, isolating bacteria capable of utilizing LDPE as a carbon source—providing a starting point for developing biological solutions to plastic pollution remediation.
Microbial degradation of virgin polyethylene by bacteria isolated from a landfill site
Researchers isolated bacteria from landfill sites that had been exposed to plastic waste for up to 17 years and tested their ability to break down high-density polyethylene (HDPE), a common plastic used in packaging. The bacterium Bacillus cereus achieved the highest degradation at only 1.78% weight loss, confirming that plastic biodegradation in landfills is an extremely slow process.
Microplastic accumulation in soils: Unlocking the mechanism and biodegradation pathway
Researchers reviewed how microplastics accumulate in soil and break down biologically, finding that certain microorganisms can form biofilms on plastic surfaces and use enzymes to slowly degrade the polymers — though conditions like pH, temperature, and moisture must be optimized and new plastic-degrading microbes need to be identified before this approach can be widely applied.
Putative degraders of low‐density polyethylene‐derived compounds are ubiquitous members of plastic‐associated bacterial communities in the marine environment
This study compared bacterial communities on plastic debris from the Pacific, North Atlantic, and northern Adriatic to identify potential plastic-degrading microbes, finding that putative LDPE-degraders are widespread and common members of ocean plastic biofilms. The widespread distribution of plastic-degrading bacteria in ocean environments suggests that biological plastic breakdown is occurring in the ocean, but at an unknown rate.
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.
[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.
Isolation and characterization of new bacterial strains degrading low-density polyethylene
Researchers isolated and characterized new bacterial strains capable of degrading low-density polyethylene, one of the most common plastic polymers.

Exploitation of bacterial strains for microplastics (LDPE) biodegradation
Researchers tested five bacterial strains for their ability to biodegrade low-density polyethylene microplastics over four months. Pseudomonas aeruginosa showed the most significant degradation with an 18.2% weight loss, followed by Bacillus subtilis at 16.1%. The study demonstrates that naturally occurring soil bacteria can break down polyethylene microplastics, suggesting a potential biological approach to addressing plastic waste pollution.

Synergistic functional activity of a landfill microbial consortium in a microplastic-enriched environment
Scientists studied soil bacteria from a decades-old landfill to understand how microbes adapt to high concentrations of polyethylene and PET microplastics. They found that multiple bacterial species work together to break down these plastics, with different roles for bacteria floating freely versus those attached to plastic surfaces. While biodegradation of microplastics is possible, it is slow, and understanding these natural processes could eventually help with cleanup efforts.
