Summary

The marine bacterium Vibrio gazogenes was shown to secrete an active PET hydrolase and degrade PET plastics in biofilms, with primary degradation products BHET and terephthalic acid found to profoundly affect c-di-GMP and cAMP signaling and quorum sensing, revealing how PET breakdown products alter bacterial physiology.

PE PET

This study provides the first evidence that Vibrio gazogenes DSM 21264 secretes an active polyethylene terephthalate (PET) hydrolase and degrades the polymer using PET6 when growing in biofilms on foils and microplastic particles. The study further provides evidence that the primary PET degradation products bis(2-hydroxyethyl) terephthalate (BHET) and terephthalic acid (TPA) may have a profound impact on the global QS, c-di-GMP, and cAMP-CRP signaling of V. gazogenes and its capability to colonize plastic particles in the marine environment.
