Abstract: | Besides carotenoids a complex of flexirubin-type pigments was isolated from the gliding bacteriumCytophaga johnsonae Cy j1 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 inFlexibacter elegans.Non-Standard Abbreviations FT Fourier transformation - HPLC high pressure liquid chromatography - M+ molecular ion - M/M resolution of mass spectrometer - mu mass units - tR retention time - TLC thin layer chromatographyPart 16: Investigations on metabolites of microorganisms.
