Prodigiosin is a natural pigment produced by Serratia marcescens. The pigment was grown in MacConkey
agar and Luria Bertani agar. Growth of the pigment was higher in Luria Bertani agar when compared with
MacConkey agar. Antibacterial activity was evaluated using test organisms such as E.coli, Pseudomonas
sp. by well diffusion method. The pigment was impregnated on the surface of the test organism in different
concentrations and incubated. The clear inhibition zones that formed around the well indicates antibacterial
activity.
Keywords: Ecoli. Prodigiosin. Pseudomonas sp. Serratia marcescens.
