Fig. 6: Schematic figure to represent the PHAs metabolism in Ps. protegens (MAG1) and its potential for plastic upcycling.

In the left-up, we display the growth (assessed by OD600nm) values obtained on PHB and PHO as the sole carbon source; B and O are controls without bacterial inoculum and Pp is the controls without PHAs. Cluster of genes (arrows depending on their transcription direction) associated with PHA synthesis (and found in MAG1) are at the figure bottom. In right-middle, we display how plastic monomers or plasticizers can be metabolized thought protocatechuate pathways allowing the growth of Ps. protegens and synthesis of PHAs. These PHAs can be catabolized and synthetized through fatty acid beta-oxidation pathway.
