Oxidative Depolymerization of Lignosulfonates for Muconic Acid Production Using Recombinant Pseudomonas Putida CJ475

Lignosulfonate, a macromolecular byproduct derived from the paper and pulp industry, is a promising feedstock for bioconversion processes due to its rich carbon content and widespread availability. We here present an approach for the production of muconic acid through the optimization of the oxidative depolymerization of lignosulfonate and its further conversion using a recombinant Pseudomonas putida strain. This process yielded a stream containing a diverse mixture of low-molecular-weight aromatic compounds, the highest yield being that of vanillin, of 5.77 wt
