Concept
Streptomyces
Summary
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.
Streptomycetes are characterised by a complex secondary metabolism. Between 5-23% (average: 12%) of the protein-coding genes of each Streptomyces species are implicated in secondary metabolism. Streptomycetes produce over two-thirds of the clinically useful antibiotics of natural origin (e.g., neomycin, streptomycin, cypemycin, grisemycin, bottromycins and chloramphenicol). The antibiotic streptomycin takes its name directly from Streptomyces. Streptomycetes are infrequent pathogens, though infections in humans, such as mycetoma, can be caused by S. somaliensis and S. sudanensis, and in plants can be caused by S. caviscabies, S. acidiscabies, S. turgidiscabies and S. scabies.
List of Streptomyces species
Streptomyces is the type genus of the family Streptomycetaceae and currently covers more than 700 species with the number increasing every year. It is estimated that the total number of Streptomyces species is close to 1600. Acidophilic and acid-tolerant strains that were initially classified under this genus have later been moved to Kitasatospora (1997) and Streptacidiphilus (2003). Species nomenclature are usually based on their color of hyphae and spores.
Saccharopolyspora erythraea was formerly placed in this genus (as Streptomyces erythraeus).
The genus Streptomyces includes aerobic, Gram-positive, multicellular, filamentous bacteria that produce well-developed vegetative hyphae (between 0.5-2.0 μm in diameter) with branches.
