摘要：

Biosynthesis of flexirubin by F. elegans (Cytophagaceae) is closely linked to growth. Out of a number of experimental conditions tested, only lowering of the pH of the medium to slightly acid conditions led to a reduced specific pigment content. The latter returned very slowly to normal when the pH was increased again. Under no conditions was a stimulation of pigment synthesis observed. The following 14C-labeled compounds were incorporated into flexirubin with sufficiently high efficiency to accept them as precursors:acetate, malonate, tyrosine and methionine.
