Polsinelli, M. (University of Pavia, Pavia, Italy), and Maria Beretta. Genetic recombination in crosses between Streptomyces aureofaciens and Streptomyces rimosus. J. Bacteriol. 91:63-68. 1966.-Biochemical mutants were obtained from Streptomyces rimosus and S. aureofaciens by ultraviolet irradiation. Crosses were performed between auxotrophic strains of S. rimosus and S. aureofaciens with posit...

Streptomyces aureofaciens is a Gram-positive actinomycete that produces the antibiotics tetracycline and chlortetracycline. Here, we report the assembly and initial annotation of the draft genome sequence of S. aureofaciens ATCC strain 10762.

Tetracyclines are broad spectrum antibiotic, belong to the family of polyketide antibiotic ,produced by Streptomyces aureofaciens of actinobacteria. The organism Streptomyces aureofaciens 325 was obtained MTCC and cultured on the starch casein media. Screening the organism for the production was confirmed by antibiogram test. The production media was optimized by using carbon sources, and nitro...

A polyphasic study was undertaken to establish the taxonomic position of a rhizosphere isolate that had been assigned provisionally to the genus Kitasatospora. The organism, isolate F18-98(T), was found to have chemical and morphological properties that were consistent with its classification as a Kitasatospora strain. Direct 16S rDNA sequence data confirmed the taxonomic position of the strain...

some kinetic properties of nad+- and nadp+- dependent glucose 6-phosphatedehydrogenase (g6pd) purified from streptomyces aureofaciens were studied. both nadh andnadph inhibited the enzyme competitively and noncompetitively, with respect to the correspondingcoenzymes and glucose 6-phosphate, respectively. atp inhibited the nad+ - linked reaction but not thatof the nadp+- linked activity. the inh...

Streptomyces lavendulae subsp. lavendulae CCM 3239 produces the angucycline antibiotic auricin and was thought to be the type strain of Streptomyces aureofaciens We report the complete genome sequence of this strain, which consists of a linear chromosome and the linear plasmid pSA3239, and demonstrate it to be S. lavendulae subsp. lavendulae.

A number of nitriles and cyano compounds inhibited chlorination by Streptomyces aureofaciens. In most cases, this inhibition was enhanced by bromide. Methylene blue and p-amino-propiophenone reversed the inhibition to some extent.

Glucose 6-phosphate dehydrogenase (G6PD) was purified from Streptomyces aureofaciens and inactivated with butanedione and diethylpyrocarbonate. Incubation of the enzyme with butanedione resulted in a rapid activity loss (80%) within 5 min, followed by a slow phase using a molar ratio to enzyme concentration of 100. Fluorescence studies showed a conformational change in the butanedione-modified ...

Streptomyces aureofaciens growth in chemically defined medium is actively associated with the secretion of low-molecular-weight nucleic acid-related substances and is linked to low availability of phosphate. Thirteen pure compounds were isolated, of which seven were identified.

We previously identified a polyketide synthase gene cluster, aur1, responsible for the production of the angucycline antibiotic auricin in Streptomyces aureofaciens CCM 3239. A sequence analysis of the aur1 flanking regions revealed the presence of several genes encoding proteins homologous to those for Streptomyces linear plasmid replication, partitioning and telomere-binding. Pulse-field gel ...
