CAROTENOID PIGMENTS OF STIGMATELLA AURANTIACA (MYXOBACTERALES) .I. MINOR CAROTENOIDS

In this first article on the carotenoids of Myxobacterales we report on the minor carotenoids of Stigmatella aurantiaca: phytoene, phytofluene, lycopene, γ-carotene, 4-keto-γ-carotene, 1′,2′-dihydro-1′-hydroxy-γ-carotene, 4-keto-1′,2′-dihydro-1′-hydroxy-γ-carotene, 4-keto-1′,2′-dihydro-1′-hydroxy-torulene, and 1,2,1′,2′-tetrahydro-1,1′-dihydroxy-lycopene. These pigments account for about 10% of total carotenoids. © 1969 Springer-Verlag.
