Isolation And Characterization of Cranomycin, A New Antibiotic

Abstract

A new crystalline antibiotic named cranomycin has been isolated from culture broth of Streptomyces SE-801, new species.¹⁾

Cranomycin is a basic antibiotic and active principally against Gram-positive bacteria and some phytopathogenic microorganisms, such as Xanthomonas oryzae, and toxic to mice. Cranomycin is effective in the curative test against the bacterial blight leaf of rice-plants.

In the present publication, production process and characterization of cranomycin are described.
