Streptomyces venezuelae

Streptomyces venezuelae is a species of soil-dwelling Gram-positive bacterium of the genus Streptomyces. S. venezuelae is filamentous. In its spore-bearing stage, hyphae perfuse both above ground as aerial hyphae and in the soil substrate. Chloramphenicol, the first antibiotic to be manufactured synthetically on a large scale, was originally derived from S. venezuelae.
