2,4 pyridine dicarboxylic acid (2,4 PDCA) is an analogue of terephthalate, and hence a target chemical in the field of bio-based plastics. Here, Pseudomonas putida KT2440 strains were engineered to efficiently drive the metabolism of lignin-derived monoaromatics towards 2,4 PDCA in a resting cells-based bioprocess that alleviates growth-coupled limitations and allows biocatalysts recycling. Native β-ketoadipate pathway was blocked by replacing protocatechuate 3,4-dioxygenase by the exogenous LigAB extradiol dioxygenase. Overexpression of pcaK encoding a transporter increased 8-fold 2,4 PDCA productivity from protocatechuate, reaching the highest value reported so far (0.58 g L^-1h⁻¹). Overexpression of the 4-hydroxybenzoate monooxygenase (pobA) speed up drastically the production of 2,4 PDCA from 4-hydroxybenzoate (0.056 g L^-1h⁻¹) or p-coumarate (0.012 g L^-1h⁻¹) achieving values 15-fold higher than those reported with Rhodococcus jostii biocatalysts. 2,4 PDCA was also bioproduced by using soda lignin as feedstock, paving the way for future polymeric lignin valorization approaches.
