BRIEF REVIEW ON MICROBIAL PIGMENTS AND THEIR PROSPECTS

The large number of microorganisms present in nature, as well as their ease of cultivation, contributes to the advantage in the extraction and manufacture of natural colours or pigments. Microbial pigments are classified as secondary metabolites and are mostly formed owing to poor metabolism during stressful situations. These microbial pigments are safe for human use, have increased biodegradability, and are more environmentally friendly, making them suitable for a variety of applications in the pharmaceutical, textile, cosmetic and food sectors. The therapeutic character of bacterial pigments is demonstrated by their antibacterial, anticancer, cytotoxic and outstanding antioxidant activities. Identifying novel microbiological sources and improving process parameters are two areas of focus for affordable pigment production. This also suggests that future generations will rely on microbial pigments rather than manmade colorants for a sustainable lifestyle. This article has attempted to take a brief idea on microbial pigments and their prospects in different sectors.
