Biosynthesis of prodigiosin, a secondary metabolite of Serratia marcescens.
Prodigiosenes (prodigiosin and prodigiosin-like pigments) are known to be synthesized by only one genus of Eubacteriales and by two genera of Actinomycetales. Biosynthesis by Serratia marcescens occurs over a relatively narrow range of temperatures, although the bacteria grow over a broad range. When cultures of S. marcescens were incubated at 27 C in 1.0% casein hydrolysate, viable count and p...
متن کاملFactors influencing pigment production in a mutant strain of Serratia marcescens.
A high frequency of mutations affecting color production is characteristic of the HY strain of Serratia marcescens. After ultraviolet irradiation, mutants ranging from white, through pink and orange, to deep red shades darker than the wild type can be obtained (Labrum and Bunting, 1953). Many of the white and pink mutants emit diffusible substances which can be utilized by other color mutants g...
متن کاملEvidence for a tricarboxylic acid cycle in Serratia marcescens.
Wrede and Rothhaas (1934) proposed a tripyrrylmethene structure for the red pigment extracted from Serratia marcescens. This structure was supported by Hubbard and Rimington (1950) because of the similarity in spectral properties between extracted pigment and a synthetic tripyrrylmethene compound. Recent investigations (Williams et al., 1956) have demonstrated that pigment identical in spectral...
متن کاملStudies on pigmentation of serratia marcescens. III. The characteristics of an orange variant.
The production of color variants of Serratia marcescens by means of ultraviolet light irradiation has been reported by Labrum and Bunting (1953). These variants exhibited several shades of pink, orange, or white pigmentation, and differed markedly from the natural or wild-type red color. Rizki (1954a) demonstrated that several of these pink, orange, and white variants were capable of inducing r...
