Abstract
Pigment from micro-organism is one of the emerging areas of research and many pigments have been extensively studied for their therapeutic potential.

Our aim was to analyze the anticancer property of a red pigment extracted from Serratia marcescens JGI 27against HepG2 and Jurkat cell lines. The cel l viability was evaluated by MTT assay. As the red pigment extracte d from S. marcescens exhibited high cytotoxicity to the tested cancer cell lines, the pigment production was optimized under various culture conditions like, temperature shock, incubation time, carbon sources, nitrogen sources and metal ions. Pigment yield was analyzed spectrophotometrically at 487 nm.

Keywords
