Electron microscope study of the multiplication of the actinophage affecting Streptomyces griseus.

Electron Microscope Study of the Multiplication of the Actinophage Affecting

Although fundamental problems relating to phage multiplication have been attacked with various genetic, biochemical, and morphologic methods, important questions still remain to be solved especially concerning gene and chromosome replications and DNA synthesis in phages. Recently phages which attack species of Streptomyces have become the subject of study by many workers because of the industri...

جداسازی و تأیید مولکولی سریع استرپتومایسس های تولید کننده آنتی بیوتیک استرپتومایسین

Introduction: Streptomyces species are mycelial, aerobic gram-positive bacteria that are isolated from soil and produce a diverse range of antibiotics. Streptomyces griseus produces the antibiotic, streptomycin and forms spores even in a liquid culture. The gene cluster for the production of Streptomycin antibiotic contains strR gene that encodes StrR, a pathway-specific regulator. Then, this p...

Oxidation of Meloxicam by Streptomyces griseus

The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...

Enopeptin A, a novel depsipeptide antibiotic with anti-bacteriophage activity.

Using actinophage Bl and Streptomyces griseus as a convenient prescreening1* for antiviral substances, a new antibiotic, enopeptin A was isolated from a culture broth of Streptomyces sp. RK-1051. Strain RK-1051 was isolated from a soil sample collected in Tsuruoka city, Yamagata Prefecture, Japan, and deposited at the Fermentation Research Institute, Agency of Industrial Science and Technology,...
