Dyes and pigments are used by humans to add colors in their life. Due to the hazardous impact of synthetic azo dyes on the environment and also on human health, there is an increasing demand for natural dyes in the food, cosmetics, pharmaceutical, and textile industry. Natural dyes of biological origin have been extracted from plants, algae, and various pigment-producing microorganisms. Microorganisms are fast-growing and it produces a large amount of the pigment using cheap carbon and energy sources for their growth. It is easy and inexpensive to extract microbial pigments than pigments from plant sources. Also, microbial pigments are biodegradable and have no negative impact on the environment. Prodigiosin is a family of tripyrrole ring-containing natural red pigment produced as a secondary metabolite by the Gram-negative bacteria, Serratia marcescens which is reported to have antibacterial, antifungal and anti-proliferative activity. In the present study, prodigiosin pigment was produced and extracted from an already characterized Serratia marcescens sp. using organic solvent. The extracted pigment was used to dye cotton and synthetic fabrics. Antibacterial activity of dyed fabrics against skin infections causing pathogenic bacteria was assessed by the agar diffusion method. The study reveals that the dyed fabrics have antimicrobial activity against the pathogenic test organisms. Thus it can be concluded that apart from imparting bright colors, prodigiosin also imparts anti-microbial finish to the textile fabrics.
