Interpretive Summary: Recently, itaconic acid has attracted much attention as a biobased building block chemical. It is used as a monomer for production of superabsorbent polymers, resins, plastics, paints, and synthetic fibers. It has strong potential to replace petroleum based acrylic acid or methylacrylic acid for production of plastics which will create huge market for it. Itaconic acid is produced from glucose by fermentation with a fungal strain. The yield and production cost need to be lowered. Moreover, the agricultural biomass derived sugars (non-food source) should replace glucose used in industry. This timely review paper summarizes the latest progress on enhancing the yield and rate of itaconic acid production. The article is of great value to all academic, industrial, and government scientists who are working or planning to work on production of this important platform chemical.

Technical Abstract: Recently, itaconic acid (IA), an unsaturated C5-dicarboxylic acid, has attracted much attention as a biobased building block chemical. It is produced industrially (> 80 g L**-1) from glucose by fermentation with Aspergillus terreus. The titer is low compared with citric acid production (> 200 g L**-1). This review summarizes the latest progress on enhancing the yield and productivity of IA production. IA biosynthesis involves the decarboxylation of the TCA cycle intermediate cis-aconitate through the action of cis-aconitate decarboxylase (CAD) enzyme encoded by the CadA gene in A. terreus. A number of recombinant microorganisms have been developed in an effort to overproduce it. IA is used as a monomer for production of superabsorbent polymer, resins, plastics, paints, and synthetic fibers. Its applications as a platform chemical are highlighted. It has a strong potential to replace petroleum based methylacrylic acid in industry which will create huge market for IA.
