ABSTRACT
Wide applications of synthetic pigments in the food, cosmetics, textiles is increasing in recent era, but due to the harmful effect of synthetic dyes, a number of natural pigments are produced by plants, animals and microorganisms. As the production processes of natural pigment from the biological source make the high market price hence low-cost processes are required to replace synthetic pigments. The main objective of the present research work was to evaluate the renewable, cheap, easily available carbon sources as alternative substrates for production of carotenoid pigment by yeast Rhodotorula glutinis. Renewable carbon sources such as banana peel waste, corn-steep liquor collected from starch factory, dairy effluent collected from dairy industry and sugar industry effluent were tested as economically feasible cheap carbon sources for pigment production by yeast R. glutinis. The results obtained revealed that banana peel waste was found to be the best cheap, easily available substrate for pigment production in R. glutinis followed by banana peel, corn steep liquor and dairy industry effluent was also found to favours the growth of yeast. Utilization of banana peel, corn steep liquor, dairy and sugar industry effluents can be used as growth medium for carotenoid production by Rhodotorula, provides economic benefits and reduce production cost of pigment and help in reduction of environmental pollution.
