| Abstract: | A violet pigment (violacein) bacterial isolate AMA‐5 was isolated from soil samples collected from Achanakmar Biosphere Reserve, Mungeli district, Chhattisgarh, India. The yield of biocolor from this isolate was screened in minimal medium after 48 h of incubation at 37°C ± 2°C temperature. The violet pigment was extracted in ethanol. It was also observed that ammonium chloride (2.5 g/1000 mL) as a nitrogen source is the best to enhance AMA‐5 pigment production among other nitrogen sources (ammonium sulfate, tryptophan, ammonium iron sulfate, and peptone). The Sanger sequencing of 16S rDNA of strain AMA‐5 showed similarity with Chromobacterium piscinae. From the available literature and research articles, it was assumed that this violet color pigment is violacein. It was further verified by conducting high‐performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR), and proton nuclear magnetic resonance (1H‐NMR) analysis. The violet biocolor that extracted was used in cotton and polyester fabric dyeing. After the fabrics treated with sodium chloride as a mordant were completely dried, it was identified that the color was solidifying. Overall study showed that C. piscinae AMA‐5 has good potential for production of violacein, which is the most important industrial natural dye used to add color to textile products.
