Selective separation of citric acid and process optimization for its recovery from fermented broth through precipitation and acid hydrolysis were tried. A mathematical model has been proposed for yield. The experimental values are in good agreement with predicted values; the correlation coefficient was found to 0.9198.

Fungal production of citric acid
Biotechnology Advances, 1995Citric acid is the principal organic acid found in citrus fruits. To meet increasing demands it is produced from carbohydrate feedstock by fermentation with the fungus Aspergillus niger and the yeasts of Candida spp. Effect of various fermentation conditions and the biochemistry of citric acid formation by A. niger have been discussed.

Citric acid is one of the most widely used organic acids, and its annual worldwide production reached 1.6 million ton during 2009. It is used as an acidulant and preservative in the food industry, and also as a complexing agent in the pharmaceutical and cosmetic industries. Citric acid is also used as a complexing and chelating agent in metal treatment,

Citric acid metabolism in periodontosis
Archives of Oral Biology, 1964Abstract The citric acid content in blood is apparently elevated in patients with diffuse atrophy of the alveolar bone (periodontosis). In the periodontosis cases, the amount of citric acid excreted in urine during 2 hr after intravenous administration of sodium citrate is significantly increased in comparison with that of normal controls.

Summary Citric acid is one of the most important acids. It is the principal food acid, used in preparation of soft drinks and syrups. The first commercial citric acid was produced from citrus fruits, but it was discovered that citric acid could be produced on a commercial scale by some microorganisms, especially Aspergillus spp.

In the recent gasometric micro method for the determination of lactic acid in blood devised by Avery and Hastings which measures the carbon dioxide evolved upon oxidation with permanganate, these investigators obtained more carbon dioxide than could be accounted for by the lactic acid known to be present.

Chapter 4 offers an extensive description of the citric acid chemistry. It includes presentation of total syntheses of citric acid, preparations of labeled citric acid, typical reactions – neutralization, degradation, oxidation, esterification, formation of anhydrides, amides, citrate-based siderophores and other compounds.
