Summary To drive innovation in chemical and material applications beyond what has been afforded by the mature petrochemical industry, new molecules that possess diverse chemical functionality are needed. One source of such molecules lies in the varied metabolic pathways that soil microbes utilize to catabolize aromatic compounds generated during plant decomposition. Here, we have engineered Pseudomonas putida KT2440 to convert these aromatic compounds to 15 catabolic intermediates that exhibit substantial chemical diversity. Bioreactor cultivations, analytical methods, and bench-scale separations were developed to enable production (up to 58 g/L), detection, and purification of each target molecule. We further engineered strains for production of a subset of these molecules from glucose, achieving a 41% molar yield of muconic acid. Finally, we produce materials from three compounds to illustrate the potential for realizing performance-advantaged properties relative to petroleum-derived analogs.
