Streptomyces rimosus is a Gram-positive, aerobic, filamentous, rod-shaped bacterium, that belongs to the Actinomycetes group.  The chains of S. rimosus cells often branch to form a network of mycelium in soil and are responsible for the musty odor of soil. Streptomyces rimosus produces the antibiotic tetracycline, and is the industrial producer of oxytetracyclin.
