Itaconic
Acid
Fermentation
Itaconic acid is used as a resin in detergents. The transformation of citric acid by Aspergillus terreus can be used for commercial production of itaconic acid. Fermentation process involves a well-aerated molasses-mineral salts medium at a pH, below 2.2. At higher pH this microbe degrades itaconic acid. Like citric acid, low levels of trace metals must be used to achieve acceptable product yields.
