IDENTIFICATION OF THE STREPTOMYCES STRAIN KS3-5

An actinomycete, designated strain KS3-5, was isolated from a soil sam ple collected from Kaohsiung, Taiwan, ROC. This organism is capable of producing a series of antibiotics that strongly inhibit the growth of Gram-positive and Gram-negative bacteria and yeast-like fungi. The sp ore morphology and cell wall chemotype suggest that strain KS3-5 is a streptomycete. Further cultural and physiological characterization and the DNA homology suggest that strain KS3-5 is identical to Streptomyc es toxytricini.
