Abstract: Bacterial pigments are emerging as sustainable and biocompatible alternatives to synthetic colorants. Prodigiosin, a red secondary metabolite, was extracted from Serratia rubidaea KAP (LC201792), isolated from oil-contaminated soil and characterized. Ethanol was identified as the optimal solvent for pigment extraction. Characterization through UV-Visible spectrophotometry, FTIR, GC-MS, and HPLC confirmed the molecular identity of prodigiosin. A maximum absorbance peak at 534 nm was observed via UV-Visible spectrophotometry, while FTIR analysis identified key functional groups, including -NH, C=C, and CH stretches. The antimicrobial assay revealed selective activity against Gram-positive bacteria. Prodigiosin demonstrated a higher antioxidant efficacy of 96.12%, highlighting potential as a natural antioxidant. Furthermore, this study highlights its application as a dye that showed excellent color fastness on diverse substrates, including nylon, silk, polyester, candles, paper, and plastic, reinforcing its viability as an eco-friendly alternative to synthetic dyes.
