Abstract

Benzoic acid is one of the most commonly used food preservatives, but currently exclusively produced in petrochemical processes. In this study, we describe a bio-based production pathway using an engineered strain of Pseudomonas taiwanensis. In a phenylalanine-overproducing strain, we heterologously expressed bacterial, yeast, and plant genes to achieve production of benzoate via a β-oxidation pathway. Strategic disruption of the native Pseudomonas benzoate degradation pathway further allowed the production of catechol and cis,cis-muconate. Taken together, this work demonstrates new routes for the microbial production of these industrially relevant chemicals from renewable resources.
