Definition: A genus of nonmotile, aerobic, gram-positive bacteria (family Streptomycetaceae) that grow in the form of a many-branched mycelium; conidia are produced in chains on aerial hyphae. These organisms (several hundred species in the genus) are predominantly saprophytic soil forms; some are parasitic on plants or animals; many produce antibiotics. The type species is Streptomyces albus.
