ABSTRACT

Microorganism-mediated development of commercially useful goods has increased steadily in recent years. Microbial fermentation produces organic acids, which are essential components. Due to many advantages such as high purity, less environmental contamination and cost effectiveness, microbial production of organic acids has been steadily increasing over traditional chemical methods. The substrates as raw materials and fermentation medium should be less expensive, readily available globally and in large quantities for effective processing. Citric acid is a biodegradable and environmentally friendly compound used extensively in the food, pharmaceutical and cosmetic industries. To fulfil the increasing demand of citric acid in industries requires the larger production in an eco-friendly way. In industrial processing, submerged fermentation of starch or sucrose-based media is used for citric acid production. Valuable agro wastes such as wheatbran, rice straw, sugar cane,molasses is suitable, inexpensive and used as starch or sucrose-based media for the production of citric acid. In this review, application, substrate and environmental condition required for citric acid production is discussed along with microorganisms which are highly useful for citric acid production. Keywords: citric acid, agricultural waste, submerged fermentation
