RT Journal Article T1 Fumaric Acid Production: A Biorefinery Perspective A1 Martín Domínguez, Víctor A1 Estevez, Juliana A1 Ojembarrena Jiménez, Francisco De Borja A1 Santos Mazorra, Victoria Eugenia A1 Ladero Galán, Miguel AB The increasing scarcity of fossil raw materials, together with the need to develop new processes and technology based on renewable sources, and the need to dispose of an increasing amount of biomass-derived waste, have boosted the concept of biorefineries. Both 1G and 2G biorefineries are focused on the obtention of biofuels, chemicals, materials, food and feed from biomass, a renewable resource. Fumaric acid, and most compounds involved in the Kreb cycle, are considered key platform chemicals, not only for being acidulants and additives in the food industry, but also for their prospective use as monomers. This review is focused on the biotechnological processes based on fungi, mainly of the Rhizopus genus, whose main product is fumaric acid, on the process conditions, the bioreactors and modes of operation and on the purification of the acid once it is produced.
