Citric acid is a tri carboxylic organic acid, soluble in water with pleasant taste and is the most important acid used in the food industries. The present work deals with determination of optimum growth conditions for citric acid production by submerged fermentation technology using Wild strain of Aspergillus Niger. The Fermentation is carried on by providing various kinds of growth conditions like different temperatures, pH and different combinations of media of Paddy and Sorghum and the combination at which the yield of Citric acid is maximum is determined as optimum conditions for Citric Ac...
Citric acid is a tri carboxylic organic acid, soluble in water with pleasant taste and is the most important acid used in the food industries. The present work deals with determination of optimum growth conditions for citric acid production by submerged fermentation technology using Wild strain of Aspergillus Niger. The Fermentation is carried on by providing various kinds of growth conditions like different temperatures, pH and different combinations of media of Paddy and Sorghum and the combination at which the yield of Citric acid is maximum is determined as optimum conditions for Citric Acid production. By using the Response Surface Methodology we can optimize the production. The increasing use of Citric acid in a variety of industries has demanded a steadily increase in citric acid production. Recently because of its easy biodegradability, this organic acid has also found a ready acceptance in the detergent industry in place of phosphates and in the removal of sulfur in stack gases a process applicable to power stations. If we produce citric acid by malted grains, it will be economically feasible
