INTERACTION OF TETRACYCLINE WITH PROTEIN SYNTHESIZING SYSTEM OF STREPTOMYCES AUREOFACIENS

Production of tetracycline by Streptomyces aureofaciens in synthetic media.

Characterization of restriction endonuclease activities in tetracycline producing strains of Streptomyces aureofaciens.

We have tested several strains of Streptomyces aureofaciens from different sources for restriction endonuclease. In all tested tetracycline producing strains (B-96, NMU, 16, R8/26) restriction endonuclease was isolated and characterized (SauLPl, SauNl, SauSl, SauHPl respectively). Previously described restriction endonuclease from strain S. aureofaciens R8/26I (1) was renamed for SauHPl in this...

Effect of temperature on the coproduction of chlortetracycline and tetracycline by Streptomyces aureofaciens.

Five strains of Streptomyces aureofaciens of diverse origin and ability to incorporate chloride into chlortetracycline (CTC) were grown at five temperatures of incubation ranging from 20 to 31 C in media of high and low chloride content. Maximal accumulation of CTC and tetracycline (TC) occurred in the 23 to 25 C range. Departure from this range affected the different strains to various degrees...

study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...

Genetic Recombination in Crosses Between Streptomyces aureofaciens and Streptomyces rimosus.

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...
