Citric Acid from Aspergillus Niger

Citric acid has occupied a space in the global market due to its vast uses and applications in many industries. Aspergillus niger is used for industrial production of citric acid due to its property of citric acid accumulation. It has found to produce certain enzymes that help accumulate large quantities of citric acid. Aspergillus niger uses carbohydrate sources to channel energy through glycolytic pathway that subsequently leads to pentose phosphate pathway and Tri carboxylic acid (TCA) cycle. Citric acid is an important organic acid which is being globally consumed and produced in large numbers. In the present study sweet orange mango and banana peels were utilized for citric acid production by Aspergillus niger and the fermentation parameters were optimized.
