Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Plasmid pND6-1 enhances the stability and conjugative transfer of co-resident companion plasmid pND6-2 in the naphthalene-degradative Pseudomonas putida strain ND6

Electronic Journal of Biotechnology, 2022
Background: Bacterial cells often harbor multiple plasmids, but the interaction between these plasmids is poorly understood. Pseudomonas putida ND6, one of the typical naphthalene-degrading bacteria, contains two annotated plasmids, pND6-1 and pND6-2 ...
