Isolation Pigment Producing Microorganism and Pigment Characterization

This research focuses on the isolation and characterization of pigment-producing microorganisms from soil samples collected across different regions of Karnataka. As concerns grow over the environmental and health impacts of synthetic dyes, microbial pigments offer a sustainable alternative with broad applications in food, textiles, cosmetics, and pharmaceuticals. Our study aims to isolate diverse pigment-producing microbes using serial dilution techniques and selective media, followed by comprehensive characterization of the extracted pigments. The pigments will be analyzed using multiple analytical techniques including UV-Visible spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy, Thin Layer Chromatography (TLC), and to determine their structural and functional properties. Additionally, we will evaluate the practical application of these pigments in the textile industry by dyeing silk fabrics and assessing color fastness properties according to international standards. This research not only contributes to the growing field of natural colorants but also promotes sustainable practices by potentially utilizing agricultural and industrial by-products in pigment production. The findings of this study may provide valuable insights into novel pigment-producing microorganisms and their potential industrial applications, advancing efforts toward more environmentally friendly and health-conscious coloring alternatives while supporting local economies through sus- tainable biotechnology.
