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.
