Abstract: Over 100 years, citric acid remains one of the most important multifunctional organic acids produced by using traditional and modern biotechnology techniques. The citric acid has a high potential and versatile compound owing to numerous industrial applications in food and pharmaceutical industries. Globally, the citric acid production crosses more than one million tonnes and the demand increases 3-4% annually. It is important to conduct more studies on microorganisms, substrates to improve the yield for the large-scale production of citric acid to meet out the demand. In this paper, through studies are made on various microorganisms and types of fermentation for the commercial production of citric acid from different inexpensive substrates like molasses, agro – industrial wastes etc.
