Production of industrial organic acid from cassava using fungi

Abstract

Objective: Citric acid an industrial organic acid produced by Aspergillus Niger from Manihot esculenta peels with different carbon and nitrogen sources. Glucose-enriched medium showed maximum yield of citric acid. Ammonium chloride and ammonium persulfate reduced the formation of citric acid. The high amount of citric acid was observed in ammonium dihydrogen phosphate-enriched source. Results and Discussion: The optimum yield of organic acid from cassava pulp in the presence of fungi was found in 20 days of fermentation with pH3 and room temperature.
