  • Abstract

    Citric acid, C3H4OH (COOH)3, was first isolated from lemon juice by a Swedish chemist, Carl Wilhelm Scheele, in 1784. Citric acid is manufactured by fermentation of cane sugar or molasses in the presence of a fungus, Aspergillus niger ATCC 9142. Fermentation of sugar by the mold Aspergillus niger ATCC 9142 is the chief commercial source of the acid. Fermentation results in the breakdown of complex organic substances into simpler ones through the action of catalysis. This project involves the production of citric acid from fungal strain of Aspergillus niger ATCC 9142, using various sources like cane molasses, beet molasses, sweet potato and grape sugar by employing various methods such as submerged and surface fermentation. The recovery of citric acid from fermented broth is generally performed through three procedures – precipitation, extraction and adsorption (mainly using ion-exchange resins). The main aim of the project is to achieve a cost reduction in citric acid production by using less expensive substrates.
