|Section2= |Section3= }} Prodigiosin is the red pigment produced by many strains of the bacterium ''Serratia marcescens'', other Gram-negative, gamma proteobacteria such as ''Vibrio psychroerythrus'' and ''Hahella chejuensis'' It is in a family of compounds termed "prodiginines", which are produced in some Gram-negative gamma proteobacteria, as well as select Gram-positive Actinobacteria (e.g. ''Streptomyces coelicolor'').〔 The name "prodigiosin" is derived from "prodigious" (''i.e.'' something marvelous). == Secondary metabolite == Prodigiosin is a secondary metabolite of ''Serratia marcescens''. Because it is easy to detect, it has been used as a model system to study secondary metabolism. Prodigiosin production has long been known to be enhanced by phosphate limitation. In low phosphate conditions, pigmented strains have been shown to grow to a higher density than unpigmented strains.〔M. Todd-Guay and P.H. Demchick. 1995.
