- Microorganism: Aspergillus niger (mainly), Candida yeast (from carbohydrates or n-alkanes) - Citric acid production is mixed growth associated , mainly take place under nitrogen and phosphate limitation after growth has ceased. - Medium requirements for high production - Carbon source: molasses or sugar solution. - Na-ferrocyanide is added to reduce Iron (1.3 ppm) and manganese (<0.1ppm). - High dissolved oxygen concentration - High sugar concentration - pH<2 - 30 o C .
