Microbial synthesis of vanillin from waste poly(ethylene terephthalate)
Joanna C. Sadler, Stephen Wallace
Abstract
product removal were key to maximising vanillin titres. Finally, we demonstrate the conversion of post-consumer PET from a plastic bottle into vanillin by coupling the pathway with enzyme-catalysed PET hydrolysis. This work demonstrates the first biological upcycling of post-consumer plastic waste into vanillin using an engineered microorganism.
