ABSTRACT
Applications of natural pigments in food, pharmaceutical and as a colorant are increasing regularly due to the hazardous effect of synthetic pigments. As the production processes of natural pigment from the biological source invest larger capital, low-cost processes are desirable so as to replace synthetic pigments. The main aim of the present investigation targets at the work the exploration of inexpensive, lowcost agro products as substituted carbon source for carotenoid pigment production by Planococcus maritimus AHJ_2. Agro-residues such as molasses, whey, and distillery spent wash were utilized as economically feasible cheap carbon sources for carotenoid pigment production. The results revealed that molasses was found to be the most effective substrate for pigment production. 1-5 % v/v concentrations of molasses were effective and maximum growth and carotenoid pigment production. Specific pigment production rate was 0.821 mg.g-1 at 5% v/v concentration of molasses. Whereas distillery spent wash was also found to be effective at 5 % v/v concentration and the specific pigment production rate obtained was 0.744mg.g-1. Whey was not found to support the growth and pigment production in the organism. Conclusively high-cost synthetic media can be replaced by low-cost agro-products for pigment production by P. maritimus AHJ_2.
