ABSTRACT
Serratia marcescens is a gram-negative, short rod-shaped, facultative anaerobic bacterium. it is commonly found in moist soil regions, grows at room temperature of about 25oC to 30oC, and is characterized morphologically and biochemically. Further identification was done by 16 srNA sequencing using BLASTN and confirmed to be Serratia marcescens. S. marcescens is noted for producing secondary metabolites called prodigiosin, a bioactive compound. the extraction process was carried out through the fermentation of prodigiosin pigment. The pigment was extracted by thin layer chromatography and the sample was purified by column chromatography. The purified sample was subjected to analysis of the functional group through FTIR analysis. The prodigiosin pigment was coated onto the cotton fabrics and used as an antimicrobial, anti-oxidant, and the physical strength of the coated fabrics like thickness, air permeability, and stain resistance test. Prodigiosin has a defined role in the physiology of the strains in which it is produced and is also naturally used for wounds and medicinal properties.
