Descripción general

Citric acid also called 2-hydroxy-propane-1,2,3-tricarboxylic acid, is a component of the tricarboxylic acid cycle in all organisms. Industrial production of citric acid use fungal, yeast and citrus fruit as the major source. Aspergillus niger is majorly used for citric acid production by fermentation Manganese inhibits fermentative production of citric acid Oral supplementation of citric acid promotes tricarboxylic acid cycle and oxidative phosphorylation in mitochondria, attenuating physical fatigue.

Aplicación

Citric acidhas been used as a component of citrate buffer and Fe-free sauton′s medium. It has been used in hybridization chain reaction buffer for preequilibration of coverslips for testes sections.
