Genetics of Streptomyces rimosus, the oxytetracycline producer.
From a genetic standpoint, Streptomyces rimosus is arguably the best-characterized industrial streptomycete as the producer of oxytetracycline and other tetracycline antibiotics. Although resistance to these antibiotics has reduced their clinical use in recent years, tetracyclines have an increasing role in the treatment of emerging infections and noninfective diseases. Procedures for in vivo a...
متن کاملPRODUCTION OF OXYTETRACYCLINE BY ISOLATED WILD TYPE IRANIAN STREPTOMYCES RIMOSUS
Production of oxytetracycline by an isolated strain of Streptomyces rimosus from Iranian soil was investigated using a special fermentation medium. A comparative study was performed with standard strain PTCC 1144 using the following parameters optimum growth conditions with respect to time, pH, and different amounts of corn steep liquor. Surprisingly, the production yield of the wild strai...
متن کاملGenetic 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...
متن کاملThe temperate phages RP2 and RP3 of Streptomyces rimosus.
The oxytetracycline-producing Streptomyces rimosus strains R6-65 and R7 (ATCC 10970) are lysogenic for the two narrow-host-range phages RP2 and RP3. Both phages are released at low frequency from the lysogenic strains and form plaques on 'cured' S. rimosus strains. RP2 and RP3 are of similar shape with flexible tails and contain double-stranded DNA of about 70% G+C with cohesive ends (group B1 ...
متن کاملInfluence of Inorganic Phosphorus on Oxytetracycline Formation by Streptomyces Rimosus.
Production of oxytetracycline by Streptomyces rimosus in several chemically defined media containing graded concentrations of inorganic phosphorus was studied in shake flasks. Although high levels of inorganic phosphate have been reported to inhibit oxytetracycline formation, this study indicated that composition of the medium is an important factor in determining whether antibiotic production ...
