Prodigiosin

Prodigiosin is the 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, 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 marvelous).
