Optimization of prodigiosin production by using crude glycerol and enhancing production using gamma radiation.

Prodigiosin is a red pigment produced by . Prodigiosin is regarded as a promising drug owing to its reported characteristics of possessing anti-microbial, anti-cancer, and immunosuppressive activity. A factorial design was applied to generate a set of 32 experimental combinations to study the optimal conditions for pigment production using crude glycerol obtained from local biodiesel facility as carbon source for the growth of .
