Cycloheximide is a naturally occurring fungicide produced by the bacterium "Streptomyces griseus". Streptomycin is produced by "Streptomyces griseus". Streptomycin was discovered in 1943 from "Streptomyces griseus". Endoglycosidase H is isolated from "Streptomyces plicatus" or "Streptomyces griseus". Those genes are found in eubacteria, in algae, and are cryptic in "Streptomyces griseus". Bafilomycin A1, B1 and C1 were first isolated from "Streptomyces griseus" in 1983. It is derived from "Streptomyces griseus" and is the earliest modern agent used against tuberculosis. The name was changed in 1948 by Waksman and Henrici to "Streptomyces griseus". Streptomyces griseus is a species of bacteria in the genus "Streptomyces" commonly found in soil. "Streptomyces griseus", and "Saccharopolyspora erythraea", are capable of secondary metabolite production. "Streptomyces griseus", "Streptomyces chrysomallus" and "Streptomyces werraensis".
