A high throughput assay to detect enzymatic polyethylene oxidation.

ABSTRACT: Biological plastics deconstruction and upcycling have emerged as a sustainable alternative to traditional recycling technologies for plastics waste. The discovery and engineering of efficient thermostable poly(ethylene terephthalate) (PET) hydrolases has made biological PET recycling possible at scale; however, enzymes for non-PET plastics, which account for approximately 70% of all plastics produced, remain largely undiscovered. To accelerate the discovery of such enzymes, a high throughput screening (HTS) platform is needed. Here, we develop a HTS liquid-based assay to detect one of the first committed steps of polyolefin degradation, oxidation of the C-H bond to an aldehyde. We test 4-hydrazino-7-nitro-2,1,3-benxoxadiozole hydrazine (NBD-H), which reacts with generated aldehydes to form
