Abstract Lignosulfonate, a macromolecular byproduct derived from the paper and pulp industry, is promising feedstock for bioconversion processes due to its rich carbon content widespread availability. We here present an approach production of muconic acid through optimization oxidative depolymerization lignosulfonate further conversion using recombinant Pseudomonas putida strain. This process yielded stream containing diverse mixture low-molecular-weight aromatic compounds, highest yield being that vanillin, 5.77 wt%. When was performed with P. strain CJ475, previously engineered vanillin acid, no initially observed inhibitory effect depolymerized fraction on bacterial growth. However, simple additional extraction step ethyl acetate led successful substrate 1.3 ± 0.06 mol acid/mol in stream. study demonstrates feasibility utilizing oxidatively lignosulfonates as sustainable source biobased production. It also marks significant forward utilization lignocellulosic biomass high-value biochemical production, well providing valuable insights into development bioprocesses complex, lignin-rich feedstocks.
