Streptomyces is the largest genus of Actinobacteria and the type genus of the family Streptomycetaceae. Over 500 species of Streptomyces bacteria have been described. As with the other Actinobacteria, streptomycetes are gram-positive, and have 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.
Natamycin, also known as pimaricin, is an antifungal medication used to treat fungal infections around the eye. This includes infections of the eyelids, conjunctiva, and cornea. It is used as eyedrops. Natamycin is also used in the food industry as a preservative.
The Streptomycetaceae are a family of Actinobacteria, making up the monotypic order Streptomycetales. It includes the important genus Streptomyces. This was the original source of many antibiotics, namely streptomycin, the first antibiotic against tuberculosis.
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. Along with most other streptomycetes, S. griseus strains are well known producers of antibiotics and other such commercially significant secondary metabolites. These strains are known to be producers of 32 different structural types of bioactive compounds. Streptomycin, the first antibiotic ever reported from a bacterium, comes from strains of S. griseus. Recently, the whole genome sequence of one of its strains had been completed.
Streptomyces hygroscopicus is a bacterial species in the genus Streptomyces. It was first described by Hans Laurits Jensen in 1931.
Streptomyces alboniger is a bacterium species in the genus Streptomyces.
Streptomyces lincolnensis is a bacterium species in the type genus Streptomyces.
Streptomyces avermitilis is a species of bacteria in the genus Streptomyces. This bacterium was discovered by Satoshi Ōmura in Shizuoka Prefecture, Japan.
Streptomyces viridochromogenes is a bacterium species in the genus Streptomyces.
Common scab is a plant disease of root and tuber crops caused by a small number of Streptomyces species, specifically S. scabies, S. acidiscabies, S. turgidiscabies and others. Common scab mainly affects potato, but can also cause disease on radish, parsnip, beet, and carrot. This plant disease is found wherever these vegetables are grown.
Streptomyces abikoensis is a bacterium species from the genus Streptomyces which produces the antibiotic abikoviromycin. Streptomyces abikoensis has been isolated from Abiko in Japan.
Streptomyces albidoflavus is a bacterium species from the genus of Streptomyces which has been isolated from soil from Poland. Streptomyces albidoflavus produces dibutyl phthalate and streptothricins.
Streptomyces castelarensis is a bacterium species from the genus of Streptomyces which has been isolated from dust in Castelar in Argentina. Streptomyces castelarensis produces camphomycin.
Streptomyces cinnamoneus is a bacterium species from the genus of Streptomyces which has been isolated from soil in Japan. Streptomyces cinnamoneus produces duramycin A, duramycin B, duramycin C, carbomycin, cinnomycin and fungichromin.
Streptomyces filamentosus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces filamentosus produces caryomycin. Streptomyces filamentosus also produces the novel cyclic lipopeptide antibiotic daptomycin.
Streptomyces hiroshimensis is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces hiroshimensis produces the red pigment prodigiosin.
Streptomyces microflavus is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces microflavus produces nemadectin, fattiviracin A1, milbemycin and deoxyuridines. Streptomyces microflavus also produces the ionophore valinomycin. Streptomyces microflavus is also known to cause potato common scab disease in Korea.
Streptomyces violaceochromogenes is a bacterium species from the genus of Streptomyces which has been isolated from soil. Streptomyces violaceochromogenes produces cinerubin x, cinerubin y, arugomycin and viriplanin D.
Cytochrome P450, family 107, also known as CYP107, is a cytochrome P450 monooxygenase family in bacteria, found to be conserved and highly populated in Streptomyces and Bacillus species. The first gene identified in this family is Cytochrome P450 eryF (CYP107A1) from Saccharopolyspora erythraea. Many enzymes of this family are involved in the synthesis of macrolide antibiotics. The members of this family are widely distributed in Alphaproteobacteria, cyanobacterial, Mycobacterium, Firmicutes and Streptomyces species, which may be due to horizontal gene transfer driven by selection pressure.
