Flexirubin-type pigments in Flavobacterium

Abstract

In an organism (strain C 1/2 from Dr. P. R. Hayes, Leeds) regarded as a typical representative of the genus Flavobacterium, flexirubin-type pigments have been identified. The Flavobacterium pigments contain structural elements of both, the pigments of the genus Flexibacter and the pigments of the genus Cytophaga. As flexirubin-type pigments seem to have a rather restricted distribution among bacteria, and have formerly proved to be useful chemosystematic markers for the flexibacteria, this new observation may indicate that there is a relatively close phylogenetic relationship between this type of flavobacteria and the Cytophaga-Flexibacter group. © 1980 Springer-Verlag.
