Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. Over 700 species of Streptomyces bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have very large genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct "earthy" odor that results from production of a volatile metabolite, geosmin. Different strains of the same species may colonize very diverse environments.
Streptomyces spectabilis is a bacterium species from the genus of Streptomyces. Streptomyces spectabilis produces hangtaimycin, gentamicin, kanamycin, neomycin B, sisomycin, tobramycin, paromomycin, spectinabilin, spectinomycin, aminocyclitol, actinospectacin, prodigiosine and the streptovaricin complex.
Ribostamycin is an aminoglycoside-aminocyclitol antibiotic isolated from a streptomycete, Streptomyces ribosidificus, originally identified in a soil sample from Tsu City of Mie Prefecture in Japan. It is made up of 3 ring subunits: 2-deoxystreptamine (DOS), neosamine C, and ribose. Ribostamycin, along with other aminoglycosides with the DOS subunit, is an important broad-spectrum antibiotic with important use against human immunodeficiency virus and is considered a critically important antimicrobial by the World Health Organization., Resistance against aminoglycoside antibiotics, such as ribostamycin, is a growing concern. The resistant bacteria contain enzymes that modify the structure through phosphorylation, adenylation, and acetylation and prevent the antibiotic from being able to interact with the bacterial ribosomal RNAs.
Clavams are a class of antibiotics. This antibiotic is derived from Streptomyces clavuligerus NRRL 3585. Clavam is produced to form a new β-lactam antibiotic. This class is divided into the clavulanic acid class and the 5S clavams class. Clavulanic acid is a broad-spectrum antibiotic and 5S clavams may have anti-fungal properties. They are similar to penams, but with an oxygen substituted for the sulfur. Thus, they are also known as oxapenams.
The aminocyclitols are compounds related to cyclitols. They possess features of relative and absolute configuration that are characteristic of their class and have been extensively studied; but these features are not clearly displayed by general methods of stereochemical nomenclature, so that special methods of specifying their configuration are justified and have long been used. In other than stereochemical respects, their nomenclature should follow the general rules of organic chemistry.
Streptomyces nodosus is a bacterial species in the genus Streptomyces.
Naphthomycins are a group of closely related antimicrobial chemical compounds isolated from Streptomyces. They are considered a subclass of ansamycins.
Streptomyces isolates have yielded the majority of human, animal, and agricultural antibiotics, as well as a number of fundamental chemotherapy medicines. Streptomyces is the largest antibiotic-producing genus of Actinomycetota, producing chemotherapy, antibacterial, antifungal, antiparasitic drugs, and immunosuppressants. Streptomyces isolates are typically initiated with the aerial hyphal formation from the mycelium.
Streptomyces arenae is a bacterium species from the genus Streptomyces which has been isolated from soil from Illinois in the United States. Streptomyces arenae produces pentalenolactone, 2,5-dihydrophenylalanine, naphthocyclinone and arenaemycine.
Streptomyces aurantiogriseus is a bacterium species from the genus Streptomyces which has been isolated from soil in Russia. Streptomyces aurantiogriseus produces differolide and acetamidobenzoic acid.
Streptomyces azureus is a bacterium species from the genus of Streptomyces which has isolated from soil. Streptomyces azureus produces the antibiotic thiostrepton.
Streptomyces coeruleorubidus is a bacterium species from the genus of Streptomyces which has been isolated from marine sediment. Streptomyces coeruleorubidus produces the following medications: pacidamycin 1, baumycin B1, baumycin B2, baumycin C1, feudomycin A, feudomycin B, feudomycin C, ficellomycin, feudomycinone A, and rubomycin.
Streptomyces diastatochromogenes is a bacterium species from the genus of Streptomyces. Streptomyces diastatochromogenes produces polyketomycin, concanamycin A, concanamycin B, concanamycin C, momofulvenone A, azdimycin, toyocamycin and oligomycins.

Streptomyces halstedii produces magnamycin B, vicenistatin deltamycin A2, deltamycin A3, bafilomycin B1 and bafilomycin C1. Streptomyces halstedii also produces complex antifungal antibiotics like oligomycins and the antibiotics anisomycin and sinefungin.
Streptomyces sanglieri is a bacterium species from the genus of Streptomyces which has been isolated from soil from a hay meadow. Streptomyces sanglieri produces the antibiotic lactonamycin Z.
Streptomyces violaceusniger is a bacterium species from the genus of Streptomyces. Streptomyces violaceusniger has antifungal activity. Streptomyces violaceusniger produces isoafricanol and spirofungin.
