Abstract

Abstract: Cyanobacteria are the oxygenic photosynthesis performing prokaryotes and show a connecting link between plastids of eukaryotic autotrophs and prokaryotes. A variety of pigments, like chlorophyll, carotenoids and phycobiliproteins which exhibit different colors are present in cyanobacteria. Increasing consciousness about the harmful effects of synthetic or chemical dyes encouraged people to give more preference towards the usage of natural products, such as plant or microbial-derived colors in food and cosmetics. That is why cyanobacteria are exploited as a source of natural colors and have high commercial value in many industries. This review mainly focuses on different cyanobacterial pigments, their applications and modern biotechnological approaches such as genetic engineering, systems biology to enhance the production of biopigments for their potential use in pharmaceuticals, food, research, and cosmetics industries. Graphical abstract: Highlights: Coloration provides product attractiveness; so many coloring agents are used in textile, food and cosmetic industries. Pigments are light absorbing compounds and cyanobacteria are rich source of variety of pigments. Carotenoids have commercial value because of their brilliant colors, antioxidant property and health promoting factors. Phycobiliprotein production is directly affected by the environmental factors and the quality of the light. Cyanobacterial structural similarity with plastids elucidates their potential for genetic and metabolic engineering.
