Production of Industrial Organic Acid From Cassava using Fungi

Citric acid ,an industrial organic acid produced by Aspergillusniger from Manihotesculenta peel with different carbon and nitrogen sources. Glucose enriched medium showed maximum yield of citric acid. Ammonium chloride and ammonium persulphate reduced the formation of citric acid. The highamount of citric acid was observed in ammonium dihydrogen phosphate enriched source. The optimum yield of organic acid from cassava pulpin the presence of fungi was found in 20 days of fermentation with pH3and room temperature.
