title: Investigations of the pigments from Cytophaga johnsonae Cy jl. New flexirubin-type pigments.
abstract: Besides carotenoids a complex of flexirubin-type pigments was isolated from the gliding bacterium Cytophaga johnsonae Cy jl and separated into 6 components, which partly containe chlorine. In spite of the fact that these components still consist of pigment mixtures, the gross structures of 18 new flexirubin-type pigments could be deduced by spectroscopic and chemical investigations. The results open insights into biosynthesis and structural variety of the flexirubins, the novel non-isoprenoid pigments recently found in Flexibacter elegans.
