ClearDegradation of low density polyethylene by Bacillus species
Researchers tested the ability of two common Bacillus bacteria species to degrade low-density polyethylene and observed weight losses of about 3.5 and 2.8 percent over 30 days. Surface analysis revealed cracks, pits, and chemical oxidation on the plastic sheets exposed to the bacteria. The study suggests that these widely available microorganisms could potentially be developed as biological agents for polyethylene degradation, though the underlying enzymatic mechanisms require further investigation.

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.

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.
A 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.
Isolation and characterization of new bacterial strains degrading low-density polyethylene

Researchers isolated two strains of Bacillus amyloliquefaciens from municipal solid waste soil and demonstrated their capacity to degrade low-density polyethylene (LDPE) films, as measured by dry weight reduction, pH changes, and surface modification via FTIR and SEM analysis. The findings indicate that these bacterial strains have potential for application in LDPE bioremediation.

Researchers tested two common fungi — Aspergillus niger and Phanerochaete chrysosporium — on low-density polyethylene plastic and found they degraded up to 40% of the material in just 20 days. The findings suggest these fungi could be part of a biological strategy for breaking down one of the world's most common plastic types.
Microorganism-Based Bioremediation Approach for Plastics and Microplastics Wastes

Degradation of LDPE Using the Winogradsky Column Containing OtteriDumpsite Soil: Prediction of Mechanism and Metabolites Determination
Researchers used a soil microbial community system (Winogradsky column) to degrade low-density polyethylene (LDPE) plastic, the material used in grocery bags. The bacterial community broke down the plastic and produced identifiable metabolites, suggesting that soil microbes can slowly but measurably attack LDPE. This matters for understanding how plastic waste might naturally degrade in landfills and why microplastics form and persist in the environment.
Kinetics and Potential Mechanisms of LDPE and PBAT Microplastics Biodeterioration by Soil Bacteria Bacillus cereus L6
Scientists isolated a strain of Bacillus cereus from long-term microplastic-contaminated agricultural soil and found it could cause measurable mass loss in both LDPE (0.99% over 28 days) and biodegradable PBAT (3.58% over 28 days) agricultural film microplastics, with genome sequencing revealing the biochemical pathways involved. The faster degradation of PBAT confirms its greater biodegradability, while the LDPE results suggest even conventional polyethylene films can be partially broken down by native soil bacteria. These findings have implications for understanding how microplastics from agricultural films persist in or are gradually processed within soil ecosystems.
Phenotypic and Genomic Characterization of Polyethylene-Degrading Bacillus cereus PE-1 Enriched from Landfill Microbial Consortium
Scientists found a bacteria called Bacillus cereus PE-1 in landfill soil that can actually eat and break down plastic bags and containers (polyethylene). The bacteria damaged the plastic's surface and reduced its weight by about 5% in just 30 days, suggesting it could potentially help clean up plastic pollution in the environment. While this research is still early and needs more testing, it offers hope for using natural bacteria to tackle the growing problem of plastic waste that threatens our ecosystems and food chain.
