Microbial Degradation of Marine Plastics: Current State and Future Prospects
AI summary Read the abstract
Microbial degradation offers a promising biological pathway for breaking down the millions of tons of plastic entering the ocean each year, though current microbial capabilities remain limited compared to the scale of the problem. Understanding which microorganisms can metabolize specific polymers is critical for developing bioremediation strategies that could reduce the long-term accumulation of microplastics in marine ecosystems.
Millions of tons of plastics entering the sea each year are a substantial environmental problem. It is expected that ocean plastic pollution will increase when considering the rapidly rising rates in global plastic production, in contrast to the relatively slow...
