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.
Additionally, 11 conserved signature proteins have been identified which are found in all sequenced Streptomyces species and K. setae. These proteins are believed to be unique to the Streptomycetales order, thus provide molecular markers which can be used to distinguish this group from the rest of the Actinomycetota.
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 .
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.

Streptomyces peucetius is a bacterium species in the genus Streptomyces. S. peucetius produces the anthracycline antitumor antibiotics daunorubicin and doxorubicin (also known as adriamycin). [3] Recent work has identified an antibacterial macrolide, peucemycin, with activity against growth of S. aureus, P. hauseri, and S. enterica. [4]
Streptomyces is the largest genus of the Actinomycetota and is the type genus of the family Streptomycetaceae. [5] These are Gram-positive bacteria with high GC content [5] and are characterised by a complex secondary metabolism. [6]
Streptomyces verticillus is a species of Gram-positive bacteria in the genus Streptomyces.Whilst screening fermentation broths of this species for bioactivity in the early 1960s, Hamao Umezawa and colleagues at the Institute of Microbial Chemistry in Tokyo identified a family of glycopeptide antitumor antibiotics called the bleomycins. [1]
Streptomyces spectabilis is a bacterium species from the genus of Streptomyces. [ 1 ] [ 3 ] [ 4 ] Streptomyces spectabilis produces hangtaimycin , gentamicin , kanamycin , neomycin B , sisomycin , tobramycin , paromomycin , spectinabilin , spectinomycin , aminocyclitol , actinospectacin , prodigiosine and the streptovaricin complex.
