Two-step conversion of polyethylene into recombinant proteins using a microbial platform
AI summary Read the abstract
Researchers engineered bacteria to break down polyethylene plastic — one of the most common types of plastic pollution — and convert it into useful proteins, demonstrating a promising biological pathway for upcycling plastic waste into valuable materials.
This work demonstrates a microbial platform for the conversion of a both alkanes and plastic-derived substrates to recombinant, protein-based materials. The findings in this work can serve as a basis for future endeavors seeking to upcycle recalcitrant plastic wastes into value-added recombinant proteins.

Microbial Upcycling of Polyethylene into Recombinant Proteins
AI summary Read the abstract
Researchers engineered Pseudomonas bacteria to grow using deconstructed polyethylene (a proxy for plastic breakdown products) as their sole carbon source and produce valuable recombinant proteins. This demonstrates a route to converting plastic waste into high-value materials using microbes, potentially reducing the plastic that becomes environmental microplastics.
Engineering microbial division of labor for plastic upcycling
AI summary Read the abstract
Scientists engineered a team of two specialized bacteria that work together to break down PET plastic waste and convert it into useful chemicals. This microbial partnership outperformed single-bacteria approaches, especially when dealing with high concentrations of plastic waste. The research demonstrates a promising biological method for recycling plastic pollution into valuable materials rather than letting it accumulate in the environment.
Biotechnological model for ubiquitous mixed petroleum- and bio-based plastics degradation and upcycling into bacterial nanocellulose
AI summary Read the abstract
Researchers demonstrated a biotechnological approach for breaking down mixed petroleum-based and bio-based plastic waste and converting it into valuable bacterial nanocellulose. The system used engineered microbial communities to simultaneously degrade different plastic types that are typically difficult to recycle together. The study presents a promising model for sustainable end-of-life management of mixed plastic waste streams, addressing a key challenge in reducing plastic pollution.
Catalytic Amounts of an Antibacterial Monomer Enable the Upcycling of Poly(Ethylene Terephthalate) Waste
AI summary Read the abstract
Scientists developed a new method to recycle PET plastic waste (commonly used in bottles) into high-value antibacterial material using only small amounts of a special monomer. This approach addresses both plastic pollution and the need for antimicrobial materials, while avoiding the biotoxicity problems of traditional metal-based antibacterial agents. The technique represents a promising way to upcycle plastic waste rather than simply discarding it.
A marine bacterial community that degrades poly(ethylene terephthalate) and polyethylene
AI summary Read the abstract
Researchers discovered a marine bacterial community capable of colonizing and degrading both PET and polyethylene plastics, identified through screening hundreds of plastic waste samples. This multi-polymer degrading microbial consortium offers a promising avenue for biological plastic waste remediation.
