Abstract
AbstractA pigment is a naturally occurring colored substance that is created by plants, animals, and microbes. Pigments are utilized in a variety of industries, including food coloring, pharmaceuticals, fabric dying, cosmetics, ink plastics, coloring paints, and so on. The Natural pigments /Bio pigments are very expensive because mass production is difficult. There are more pigments in nature, but only a small number are available in large enough amounts to be useful for industry. This study is attempted to isolate a bacterial red pigmented organism from facial acne was identified as Serratia marcescens MBM‐17 according to Bergey's manual of determinative bacteriology and molecular characterization and production of red pigment was optimized at various growth factors, maximum pigment production was at pH 4, 72 h and 37 ± 2°C, that is, 15.56 g/ L. The partial purified pigment was characterized by UV–Vis, and maximum absorbance was at 533.5 nm. SEM analysis shows that the surface morphology and FTIR spectroscopy revealed the presence of prodigiosin. Prodigiosin has antibacterial efficacy against gram positive bacterial strains, Staphylococcus aureus, Bacillus sp, and gram negative bacterial strains. Klebsiella sp, Pseudomonas sp, Salmonella sp, antifungal potency against Aspergillus niger, Aspergillus flavus, Penicillium sp, Rhizopus sp, and Mucor sp, and checked the fabric dying effects of pigments. Prodigiosin used as fabric dye is applied on clothes, which shows good color tone. This study is highlighting the production of a natural pigment/drug, Prodigiosin with antimicrobial activity may be used for the manufacture of dyed dress materials and masks having antimicrobial action for public especially health workers in this pandemic situation.
