Citric acid is a tri carboxylic organic acid is the most important acid produced by fermentation used in the food and pharmaceutical industries. The present work deals with determination of optimum growth conditions for citric acid production by submerged fermentation by using strain of A.niger MTCC662 respectively. Isolation, screening and mutated the A.niger strain induced by UV irradiation, diethylsulphate and Co60 by providing different types of media and the submerged fermentation was carried out under various growth parameters like temperature, pH and media of Sorghum malt as substrate....

The enormous growth in the field of biotechnology has brought a great demand to amino acid production due to its wide variety of applications in food, medicine, cosmetics, and as a starting material in the chemical industry. Glutamic acid, a non-essential amino acid and is synthesized from a number of amino acids including Ornithine and arginine. Free glutamic acid is present in a wide variety of foods, including cheese and soy sauce and is responsible for one of the five basic tastes of the human; sense of taste .It is often used as a food additive and flavor enhancer in the form of its...
