What is Itaconic Acid?
Definition and Chemical Structure
Itaconic acid, also known as methylenesuccinic acid, is a naturally occurring dicarboxylic acid with the chemical formula C5H6O4. Its IUPAC name is methylenesuccinic acid, and it has a molecular weight of approximately 130.1 g/mol.
The molecule consists of two carboxyl (-COOH) groups and one methylene (-CH2-) group bonded to a double bond, giving it a unique reactive profile suitable for polymerization and chemical modification.
Natural Occurrence
Itaconic acid is primarily produced by certain fungi, especially the filamentous fungus Aspergillus terreus. This microorganism converts simple sugars into itaconic acid through its metabolic pathways, making it a natural product with a biological origin.
How Is Itaconic Acid Produced?
Microbial Fermentation: The Core Production Method
The most common industrial method to produce itaconic acid is microbial fermentation using the fungus Aspergillus terreus. In this process, glucose or other carbohydrate sources are fed to the fungus in controlled bioreactors. The organism metabolizes the sugars and secretes itaconic acid into the culture medium.
Advances in Biotechnology
Recent developments aim to improve yield and reduce production costs by:
- Metabolic engineering of microbial strains to enhance acid production.
- Use of alternative substrates, such as agricultural waste or lignocellulosic biomass.
- Employing genetically modified bacteria for faster and more efficient biosynthesis.
These innovations contribute to making itaconic acid a more affordable and sustainable chemical.
