Cover Story: At present, lignin (the second most abundant polymer in nature) is simply burnt, although it represents the richest natural source of aromatics. Lignin valorization is hampered by its heterogeneous composition and recalcitrance to degradation. In recent years, engineered microbial cell factories able to efficiently funnel the lignin degradation products into few metabolic intermediates have been designed based on the setup of novel metabolic pathways. This review focuses on recent success cases (at laboratory/pilot scale) based on systems metabolic engineering studies aimed at generating value-added and specialty chemicals from lignin, such as cis,cis-muconic acid for the synthesis of plastic materials. Based on these advances, lignin valorization is expected to become a reality in the short period and a central pillar in sustainability. View this paper
