Description :
Microorganisms serve as a valuable source of pigments with distinct properties and wide-ranging applications, and recent studies have revealed new opportunities for their industrial use. In this research, different pigmented bacteria were isolated from various samples. The isolates were identified as Serratia, Micrococcus, Erythrobacter, Azorhizobium, Xanthomonas sp., Sarcina sp., Rhodotorula sp., Roseomonas gilardii, K. turfanensis, Cytophaga spp., Micrococcus luteus, Micrococcus roseus, and Pseudomonas aeruginosa. The growth of these pigment-producing bacteria was influenced by factors such as temperature, pH, and salt concentration. Pigments were extracted using solvents like chloroform, methanol, and ethanol. The extracted pigments were characterized through TLC and UV spectrophotometry, with most of them identified as carotenoids. These pigments demonstrated antimicrobial properties against human pathogens, making them potentially useful for various applications in industries such as textiles, cosmetics, food, and pharmaceuticals, etc.
