prodigiosin
Prodigiosin is a red dye produced by many strains of the bacterium Serratia marcescens, as well as other Gram-negative, gamma proteobacteria such as Vibrio psychroerythrus and Hahella chejuensis. It is responsible for the pink tint occasionally found in grime that accumulates on porcelain surfaces such as bathtubs, sinks, tiles and toilet bowls. It is in the prodiginine family of compounds 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 m

Prodigiosin is a red dye produced by many strains of the bacterium Serratia marcescens, as well as other Gram-negative, gamma proteobacteria such as Vibrio psychroerythrus and Hahella chejuensis.

It is in the prodiginine family of compounds 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.
