Prodigiosin, a tripyrrole red pigment biosynthesized by serratia marcescens and other bacteria, exhibits antibacterial, anticancer, cytotoxic, immunosuppressive, and antiproliferative activities. Prodigiosin is a heterocyclic bacterial secondary metabolite belonging to the class of tripyrrole compounds, synthesized by various types of bacteria including serratia species.

The biological activities of this pigment have therapeutic potential.
Antibacterial the objectives of present study are to extract the antibiotic compound from marine isolate and to determine its in vitro antimicrobial activity against bacteria.
87% glycerol gave a better yield of pigment. Here, we report the production of prodigiosin by an endofungal bacterium serratia marcescens d1. Prodigiosin has been the subject of intense research over the last decade for its ability to induce apoptosis in several cancer cell lines. Serratia odorifera, serratia ficaria, serratia liquifaciens, serratia rubidaea, and serratia fonticola [8].
Previous reports have suggested a positive regulatory role for camp in serratia prodigiosin production.
Besides these phenotypes, biofilm formation and. Marcescens and that this inhibition could be reduced by theophylline [4], which is a potent inhibitor of purified camp phosphodiesterase activity in vitro [26]. A marine bacterial isolate serratia marcescens ibrl usm 84 was isolated from the surface of a marine sponge xestospongia testudinaria. The growth characteristics and pigment.
Serratia marcescens is a facultatively anaerobic bacterium and the most recognized producer of the hydrophobic pigment prodigiosin.
We employed both batch culture and chemostat growth methods to investigate prodigiosin function in the producing organism. For over half a century it has been known that biosynthesis of prodi giosin is inhibited when bacteria are grown at elevated temperatures, yet the fundamental. Previous work has shown that prodigiosin both increases atp production during population lag phase and approximately doubles the. Serratia species secrete several virulence factors, such as dnase, lipase, gelatinase, hemolysin, proteases, chitinase, chloroperoxidase, and multiple isozymes of alkaline phosphatase, and also produce carbapenem antibiotics, a red pigment named prodigiosin (figure 29), and biosurfactants.
Prodigiosin induces apoptosis in hematopoietic cancer cells and cells derived from other human cancers, including gastric and colon with no marked toxicity in nonmalignant cell lines.
1.1 prodigiosin structure secondary metabolites of bacterial origin include various enzymes, pigments, antibiotics etc which could be of importance to mankind in many ways. One report showed that glucose severely repressed prodigiosin production in s. The optimum conditions for pigment production in peptone glycerol broth found to be at 300c and ph 7. We employed both batch culture and chemostat growth methods to investigate prodigiosin function in the producing organism.
Prodigiosin, a red linear tripyrrole pigment, is normally secreted as a secondary metabolite of microbial origin.its native producer is the opportunistically pathogenic bacterium serratia marcescens.many researchers have focused their attention on the prodigiosin synthesis due to its antimicrobial (lapenda et al., 2015), antimalarial (papireddy et al., 2011), and anticancer (li.
A red pigment produced and identified as prodigiosin from serratia sp. Serratia marcescens produce a pigment known as prodigiosin, is
