Streptomycetaceae

A family of aerobic Gram-positive bacteria (order Actinomycetales) that produce a vegetative mycelium which does not fragment into bacillary or coccoid forms; they produce conidia which are borne on sporophores. These organisms occur primarily in the soil; some are thermophiles found in rotting manure, a few are parasitic, and many produce antibiotics. The type genus is Streptomyces.
