The discovery of a single bacterial strain capable of degrading two different types of plastic is a step toward developing practical microbial tools for plastic waste remediation.
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.
