Abstract

Using a syntrophic pigmentation assay, strains of Serratia were supplied with the uncolored bipyrrole component of the red pigment, prodigiosin. When these assays were performed at 40 C, where red strains are white, it was found that 7 of 10 normally red strains and five of eight clinical white strains formed pigment. This indicates that temperatures which prevent pigmentation in Serratia somehow interfere with synthesis of the bipyrrole component of red pigment in a majority of the strains. Also, bipyrrole has an antibiotic range of activity similar to whole pigment.
