Summary
Production of citric acid from date syrup by fermentation has been undertaken usingAspergillus niger as the producer organism. Poor yields were obtained when untreated and ferrocyanide treated date syrup were used. However, acceptable yields, in excess of 60% were obtained when the date syrup was deionised using an ion exchange column at 80°C.
