Bio colorants from microbial resources are highly explored now days for their biotechnological applications. These bio colorants serve asa potential alternate for chemically synthesized coloring agents and also numerous biomedical applications. This study deals with the isolation and optimization of chromogenic bacteria from different soil samples. The bacterial isolates (BRT-CB1 and BRT-CB2) were further subjected to pigment extraction using methanol and chloroform as active solvents. Extracted pigments were evaluated for its antioxidant efficiency against DPPH as free radical. The extracted pigments scavenge free radical with increasing concentration. The antagonistic ability of the pigments were studied on selected bacterial pathogens such as Bacillus subtilis, E. coli, Shigella sp., Klebsiella sp. and Streptococcus pyogenes where the inhibitory activity was found to be directly proportional with the increasing concentration of pigment. Thus, the work concludes that bacterial pigments are prospective metabolite which can be applied in biotechnological and biomedical applications.
