Abstract:

Bacterial pigments play an essential role in the defense mechanism of bacterial system against environmental stress. Bacterial pigments are unique secondary metabolite which exhibits various applications such as antibacterial activity against multidrug resistant strains, antioxidant efficiency against radical molecules, anti-inflammatory, anticancerous properties. In the present study, we concentrated on isolating blue pigment producing bacteria Chromobacterium violaceum (BRT-GR3). The optimum pH and temperature required for production of pigment with high intensity was found to be pH 8 at 30ºC. The presence of violacein was confirmed by the sharp peak at 567 nm. The pigment exhibited wide range of antibiotic spectrum against Gram positive and Gram negative bacteria used in the study. DPPH radical scavenging efficiency of the pigment was found to be increased with increasing concentration.
