General description

Fumaric acid can be prepared by fermentation by employing Rhizopus species. Recently, industrial-scale synthesis of fumaric acid from renewable feedstocks and lignocellulosic biomass has been proposed

Application

Fumaric acid has been used as a standard for the quantitative determination of phenolic compounds in nettle samples by HPLC.
Fumaric acid may be used in the preparation of L-Lysine-fumaric acid crystals. It may also be employed for the industrial manufacture of synthetic resins and eco-friendly/biodegradable polymers.
