Degradation of polyethylene terephthalate (PET) plastics by wastewater bacteria engineered via conjugation

Scientists engineered wastewater bacteria to break down PET plastic, one of the most common microplastic types, by transferring plastic-degrading genes through a natural DNA-sharing process. The modified bacteria could partially degrade a consumer PET product in 5 to 7 days. This proof-of-concept approach could help reduce the amount of microplastics released from wastewater treatment plants into the environment.

Biodegradation of polyethylene terephthalate microplastics by Paenibacillus naphthalenovorans PETKKU2: Response surface optimization and genomic evidence for an alternative degradation mechanism

This study identified a soil bacterium, Paenibacillus naphthalenovorans PETKKU2, isolated from a Thai landfill, as capable of degrading PET microplastics and achieving nearly 10% weight loss over 35 days under optimized conditions — through a degradation pathway distinct from the well-known PETase enzyme route. Surface analysis confirmed progressive erosion and chemical changes in the plastic. Discovering new microbial pathways for PET degradation is important for developing biological recycling and remediation strategies for one of the world's most common plastic pollutants.

Examining and identifying bacteria-mediated polyethylene terephthalate bottle waste degradation Byprops

Researchers isolated Bacillus subtilis from PET plastic waste dump sites and demonstrated that the bacterium can degrade polyethylene terephthalate microplastics over six months, with UV-pretreated PET showing the most pronounced changes including new alkyl aryl ether and alkene groups detected by FTIR and GC-MS. The findings suggest soil bacteria could offer a biodegradable solution for eliminating PET from plastic-contaminated sites.

Microbes Isolated from Landfill Soil Utilize Polyethylene Terephthalate (PET) as Their Sole Source of Carbon: An Unexplored Possibility of Bioremediation in Bangladesh

Researchers isolated six microorganisms from landfill soil near Dhaka, Bangladesh that can grow using PET plastic as their sole carbon source, identifying them as potential candidates for biological plastic degradation. This is significant because PET is one of the most widely produced and littered plastics globally, and discovering locally adapted PET-degrading microbes in developing nations opens pathways for low-cost bioremediation of plastic waste in regions with high pollution burdens.
