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 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 .
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 antibioticus was discovered by Selman Waksman and H. Boyd Woodruff, who named the bacterium Actinomyces antibioticus. [2] In their 1941 publication, Waksman and Woodruff describe their use of the "bacterial-agar plate method", in which they mixed a suspension of E. coli with washed agar containing 1.5% NaCl and 0.5% K 3 PO 4.

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

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 olivaceus is a bacterium species from the genus of Streptomyces which has been isolated from soil. [1] [3] [4] Streptomyces olivaceus produces granaticin, elloramycin, tetroazolemycin A and tetroazolemycin B. [5] [6] [7] Streptomyces olivaceus can be used to produce vitamin B12. [8] [9]
