Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. [3] Over 700 species of Streptomyces bacteria have been described. [ 4 ] [ 5 ] [ 6 ] As with the other Actinomycetota, streptomycetes are gram-positive , and have very large genomes with high GC content .
Streptomyces scabiei (also wrongly named Streptomyces scabies) [1] is a streptomycete bacterium species found in soils around the world. [2] Unlike most of the 500 or so Streptomyces species it is a plant pathogen causing corky lesions to form on tuber and root crops as well as decreasing the growth of seedlings.
Streptomyces griseus is a species of bacteria in the genus Streptomyces commonly found in soil. A few strains have been also reported from deep-sea sediments. It is a Gram-positive bacterium with high GC content .
Actinomycetota, especially Streptomyces spp., are recognized as the producers of many bioactive metabolites that are useful to humans in medicine, such as antibacterials, [18] antifungals, [19] antivirals, antithrombotics, immunomodifiers, antitumor drugs, and enzyme inhibitors; and in agriculture, including insecticides, herbicides, fungicides ...
The enzyme PBGD contains a four-amino-acid insertion which is present in all Streptomyces species and Kitasatospora setae, but not any other Actinomycetota. Similarly, a one- amino-acid insertion is present in a conserved region of adenylate kinase and is found in all Streptomyces species and K. setae, but is
Streptomyces antibioticus (previously known as Actinomyces antibioticus) is a gram-positive bacterium discovered in 1941 by Nobel-prize-winner Selman Waksman and H. Boyd Woodruff. [ 1 ] [ 2 ] Its name is derived from the Greek "strepto-" meaning "twisted", alluding to this genus ' chain-like spore production, [ 3 ] and " antibioticus ...
Actinomycetes are Gram-positive bacteria that resemble fungi in structure with a complex branched network of cells called a mycelium.Isolates of Streptomyces lavendulae from different soils around the world vary morphologically and physiologically, with some strains producing straight aerial mycelium, while other isolates form spiral mycelium. [6]
Streptomyces platensis is a bacterium species from the genus of Streptomyces which has been isolated from soil. [ 1 ] [ 3 ] [ 4 ] Streptomyces platensis produces oxytetracycline , platensimycin , migrastatin , isomigrastatin , platencin , dorrigocin A , dorrigocin B and terramycine .
