It is commercially produced from microbes namely Aspergillus Niger and Candida species.

The chemical formula of citric acid is C6H8O7.

It finds its uses in various industries namely pharmaceutical, cosmetic, food etc.

Raw material for microbial production is carbohydrates which includes molasses.

Wood shavings may also be used as raw material.

The temperature requirement is approximately 25° C.

Citric acid extraction may affect normal citric acid or TCA cycle, to compensate which anaplerotic reactions occur in organisms.
