Prodiginine (Prodigiosin-Like) Pigments from <i>Streptoverticillium rubrireticuli</i> , an Organism That Causes Pink Staining of Polyvinyl Chloride

Abstract

Red pigments were extracted from Streptoverticillium rubrireticuli strain 100-19, an organism frequently incriminated in pink staining of polyvinyl chloride. These pigments were identified as undecylprodiginine and butylcycloheptylprodiginine.
