Paper chromatography of culture media in which different strains of this organism had been grown showed that they produced many colored substances and others which are visible under UV light. Three substances which were formed early by cultures were designated Y (bright yellow in visible light, brownish-yellow in ultraviolet), R (red in visible light, fluorescing orange in ultraviolet), and M)orange in visible light, fluorescing mauve in ultraviolet). They were formed in greatest abundance. These three pigments develop in sequence, first yellow, then red and later mauve. The suggestion has been made previously that the yellow pigment is a metabolic precursor of the red pigment, and evidence for this relationship is discussed.Ultraviolet absorption spectra of all three pigments were determined. The spectrum of the yellow pigment contained an absorption maximum at 278 mµ, that of the red pigment two maxima at 278 mµ, and 525 ...Read More
