ClearMicroorganism-Based Bioremediation Approach for Plastics and Microplastics Wastes
Soil bacteria were isolated and screened for plastic-degrading capacity, with one of five isolates showing the highest low-density polyethylene (LDPE) degradation, demonstrating that soil-derived actinobacteria and other bacteria can contribute to bioremediation of plastic waste.
Microbial Allies in Plastic Degradation: Specific bacterial genera as universal plastic-degraders in various environments
Researchers identified specific bacterial genera capable of degrading multiple types of plastic across different environments including landfill soil, sewage sludge, and river water. They found that certain bacteria, such as Pseudomonas and Bacillus species, consistently appeared as effective plastic degraders regardless of the environment. The study suggests that these universal plastic-degrading bacteria could be valuable candidates for developing bioremediation strategies to address plastic pollution.
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.
