Bacteria produce a wide range of pigments such as carotenoids, melanin, violacein, prodigiosin, phycocyanin, actinorhodin, and zeaxanthin. Pigments are compounds that are widely used in industries that come in a wide variety of colors,some of which are water–soluble. Microbial pigments serve as antimicrobial agents against a wide range of pathogens. Pigments such as carotenoids, melanins, flavins, quinones, monascins, violacein, and indigo have been reported as good antimicrobial agents (Malik et al., 2012).Nontoxic nature of pigment produced by a number of microorganisms make them environmentally friendly for utilization in dye, foodstuff, pharmacy, cosmetics and other industrial purposes. Moreover natural pigments produced from biological origin have medicinal importance as been used as antioxidant, antimicrobial, additives, color intensifiers, and anticancer as well as economically friendly. Some of Bacteria capable of producing pigment with different varieties of colors are Agrobacterium aurantiacum, Staphylococcus aureus, Chromobacterium violaceum, Serratia marcescens, Bacillus Spp, Flavobacterium sp, etc. colors are Pink–red, Golden Yellow, Purple, red, Creamy and yellow respectively. Industrial production of natural food colorants by microbial fermentation has several advantages such as cheaper production, easier extraction, higher yields through strain improvement, no lack of raw materials and no seasonal. Therefore the present study aimed at reviewing pigment produced by bacteria and its application.
